ES&E NEWS MB INTRODUCES INTERIM PHOSPHOROUS REDUCTION AND NUTRIENT REMOVAL PLAN

Recently, the province of Manitoba and City of Winnipeg released the Interim Phosphorous Reduction and Nutrient Removal Implementation Plan. The Project Technical Committee has reached consensus on the scope of work for 2020, which also includes testing for interim phosphorous removal to determine how much additional phosphorous can be removed from the city’s wastewater.

The report was a collaborative work between the province and the city of Winnipeg, along with advisory input from stakeholder groups Lake Winnipeg Foundation, International Institute of Sustainable Development, Lake Winnipeg Indigenous Collective and South Basin Mayors and Reeves, It includes an overview of all three phases of Winnipeg’s plan for the North End Winnipeg Pollution Control Centre (NEWPCC) project, including cost estimates and preliminary time frame for completion of upgrades. Both the province and the city are committed to expediting the schedule whenever possible and will continue to identify opportunities to implement nutrient removal as soon as possible.

Winnipeg’s existing nutrient removal plan has been in progress since the NEWPCC Master Plan was approved in 2014.

Phase 1 will see the power supply upgrade completed in 2020 and a request for proposals on a design-build contract for

the headworks facility will be issued in 2020. Phase 2 will see design work initiated in 2020, following city council’s approval of 2020-23 sewer rates. www.gov.mb.ca

NEW REPORT ON FUTURE OF PLASTIC RECYCLING

The economics of plastic waste recycling are rapidly changing, pointing to a future where both incumbent and advanced technologies will be used, but decisive advantages for certain technologies will emerge in particular regions depending on waste streams and legislation, according to a recent Lux Research report.

The Future of Plastic Recycling looks at mechanical recycling, depolymerization, pyrolysis and solvent-based recycling , and analyzes the factors impacting the economic viability of each.

Lux points to a near-term future where no one technology takes a commanding market lead and where market conditions and global public policy will significantly impact each technology. The report aims to provide recyclers, chemical and material companies, government entities, investors, and consumer-facing brands the insight they need to make critical business and public policy decisions.

“The economics of plastic waste recycling are in continuous flux, with political and economic winds impacting the direction of the four main recycling technologies,” said Charles Willard, Lux Senior Research Associate and author of the report. www.luxresearchinc.com

Don’t you wish all partners were this easy…?

Ontario’s Region of Peel has initiated an update of its water and wastewater master plan. Lake Ontario is the Region’s source of drinking water and the discharge point for its treated wastewater. As such, the plan update primarily aims to identify a preferred lake-based water and wastewater servicing strategy to support existing servicing needs and projected growth for the region.

“The study will incorporate the latest planning information, modelling tools, historical flow/demand data and servicing studies to complete a full review and update of the servicing strategies,” officials said in a recent notice about the Master Plan update. It will also review the Region’s capital plan to meet the current servicing agreements with York Region and the City of Toronto.

Region officials are predicting a 40% increase in population by 2041, resulting in 2.94 million residents. The new Master Plan must determine how the Region’s water and wastewater infrastructure will support growth in a sustainable and financially responsible manner.

OPTIMIZING BIOSOLIDS DEWATERING TO MAXIMIZE SAVINGS

Sewage sludge dewatering offers a wide range of potential savings for operators of wastewater treatment plants. The cost of transport and disposal of dewatered solids can amount to as much as 80% of the operating costs of mechanical dewatering.

Since dryer solids result in less volume for disposal, the decision to invest in an efficient, reliable and, above all, peakperforming dewatering system is critically important to reducing operating costs.

Flottweg.com

Randy Bartholomew Supervisor of Operations at Greenway WWTP, Ontario “The Flottweg centrifuges and the dryer biosolids they produce have saved us about $900,000 annually. Our plant was able to incinerate the dryer sludge without the aid of natural gas, which equated to our high savings.

Councilor Syd Gardiner introduced the resolution to Cornwall City Council with the hope of taking it to the Association of Municipalities of Ontario for broader support. “We can be sued; we can go to jail, because it’s our responsibility,” Gardiner told fellow councilors at a December 2019 meeting.

The motion acts as a preemptive measure against Ontario’s proposed omnibus Bill 132, Better for People, Smarter for Business Act, 2019, which aims to simplify and modernize regulations to lower the costs of doing business and make it easier to interact with government. Gardiner explained that the Safe Drinking Water Act and the Aggregate Resources Act would be directly impacted by the province’s proposal and that drinking water sources could become contaminated due to a provincial decision such as an aggregate extraction permit, for instance.

“We’re responsible for anything that happens to our water, and we don’t have any say in how it’s going to be done,” Gardiner added. Proposed amendments to the Aggregate Resources Act raise the bar by requiring an application process where below water table level extraction is proposed, explained Gardiner, who expressed concern about water contamination. “This still leaves municipal council members vulnerable,” he warned in his written motion.

Among major nutrients, annual global wastewater production contains 16.6 Tg (Tg = 1 million metric tons) of nitrogen; 3.0 Tg of phosphorus; and 6.3 Tg of potassium. The full nutrient recovery from wastewater would offset 13.4% of the global demand for these nutrients in agriculture, the study found.

Based on reasonable global demand, the recovery of these nutrients from wastewater could result in revenue generation of $13.6 billion globally, with $9 billion from the recovery of nitrogen, $2.3 billion from phosphorus and $2.3 billion from potassium.

The study was funded by the Government of Canada and the UN University Institute for Water, Environment and Health.

‘DO NOT FLUSH’ WIPES LABELLING BILL MAKING HEADWAY IN CALIFORNIA

The Bill is expected to face heavy opposition from industry lobbyists as it heads to the California Assembly and Senate. In its debates at the Assembly Appropriations Committee, where companies had some input on language, many references in the Bill to wipe products containing microplastics were removed.

The Bill originally required that wipes labeled “flushable” meet the flushability specifications of the International Water Services Flushability Group. This requirement was removed from the current version of the Bill, resulting in the wipes industry lessening opposition to the legislation.

2017, essentially turning air pollution into marine pollution. Remarkably, the 35 million tonnes of effluent came from just 30 cruise ships, the study found.

The washwater effluent (a mix of water and contaminants from the heavy fuel oil) comes from “open-loop” scrubbers that immediately dispose of acidic washwater tainted with carcinogens and heavy metals into the ocean, as well as “hybrid” systems that allow ship operators to control when discharge is released into the ocean after storing it.

The study, “A whale of a problem?

California legislators have shown early support for a critical environmental Bill to rebrand hygienic wet wipes marked “flushable” with written warnings about potential clogs.

Bill AB 1672, which covers all disposable wet wipes and flushable wipes frequently used for infant care, and by adults wanting a hygienic alternative to toilet paper, has passed a critical committee vote and is headed to the California State Assembly for further debate.

The Bill was approved by a vote of 58-18 on the Assembly floor on January 30, after its introduction in February 2019.

The Bill calls for the labelling change on January 1, 2021, at which time “certain non-woven disposal products” would need “to be labeled clearly and conspicuously to communicate that they should not be flushed, as specified.”

This could potentially result in manufacturers adding a clearly visible “Do Not Flush” logo on their packaging. The logo would have to be in high contrast to other package artwork and easily visible to consumers, as with a similar Bill making headway in Washington, heading towards a vote on the House floor. www.esemag.com @ESEMAG

Report looks to create clear standard for reducing excess I/I for new sewers

A

recent report compiles methods that can be applied when sewers are first constructed to limit the risk of leakage, highlighting the need for resilient infrastructure in an age of climate change where extreme rainfall has risen sharply.

According to the multi-stakeholder report, “Reducing the Risk of Inflow and Infiltration (I/I) in New Sewer Construction”, every year across Canada, billions of litres of clean rain and groundwater leak or flow into sanitary sewers and on to sewage treatment plants.

“This entry of excess water into sewers – referred to as Inflow/Infiltration (I/I) – shortens the lifespan of pipes, takes up capacity in the sewage network, and drives up costs for Left images: Reducing the Risk of Inflow and Infiltration (I/I) in New Sewer Construction is a new report from Norton Engineering, the Institute for Catastrophic Loss Reduction, Engineers Canada, and the Standards Council of Canada.

governments and taxpayers,” states the report from Norton Engineering, the Institute for Catastrophic Loss Reduction, Engineers Canada, and the Standards Council of Canada. “Recent research in Ontario suggests that excessive I/I occurs even in new sewer systems which, if built properly, should be essentially leak-free,” adds the report, which is intended to form the basis for a new National Standard of Canada.

An initial review of flow monitoring data for 35 new subdivisions in southern Ontario indicated that 34 of them demonstrated excessive I/I rates, the report found. Addressing I/I in existing systems is a long, costly and frequently frustrating process, and the return on investment of this type of work is not often favourable, the report states. The solution, suggests the national stakeholder input incorporated into the foundational document, is to address root causes of I/I during construction of new infrastructure.

“Mitigating I/I in new construction will require concerted action on both the private and municipal sides of the property line by everyone involved in the development of new subdivisions, from conception to final acceptance,” the report’s authors state.

To highlight just a couple of the many examples on the private property side of the equation, the report refers to a pilot study in London, Ontario, which indicated that disconnecting foundation drainage systems had a substantial impact on managing I/I in a subdivision previously affected by basement flood hazards.

Additionally, the report warns that private residents can connect or reconnect sump pumps, weeping tiles and sometimes roof drainage (in older homes where former connections existed) into the sanitary sewer. These types of connections are illegal in most jurisdictions in Canada as they directly contribute to the I/I problem.

When it comes to mitigating the public side of the I/I issue, the report has a long list of suggestions, including: municipalities maintaining, updating and regularly calibrating sanitary sewer system models; enforcement of sewer use bylaw provisions; as well as consideration for having the mainline sewer www.esemag.com @ESEMAG

contractor construct the private lateral in order to reduce I/I risk. It also stresses that sewers and maintenance holes that must be located in high water conditions should be designed to water system standards for watertightness.

“Sewers overburdened by excess water limit the potential for new and expanded development in Canada’s urban areas and increases the risk of flooding and

environmental damage,” says Chantal Guay, CEO of the Standards Council of Canada. “This report is an important step toward establishing a clear national standard for preventing unacceptable I/I. Put into practice, this knowledge will save public money, reduce the risk of basement sewer backups, and contribute to more resilient urban infrastructure in Canada,” she added.

INFRASTRUCTURE Most of the AC pipes in North America were installed after the transition to the Type II steam autoclaved AC pipe, which occurred in the 1940s. Type II pipes manufactured in North America were made using 15% – 20% of asbestos, 45% – 51% of Portland cement, 32% – 34% of quartz (which contains mainly silicon oxide) and contained less than 1% of free lime (Nebesar and Riley 1983).

Echologics' ePulse is an external correlator concept that inspects pipe while it is still in service.

It is important to monitor the condition of aging asbestos cement watermains

By Rabia Mady

T

he use of asbestos cement (AC) material to manufacture pipes began in the early nineteenth century in Genoa, Italy. Dr. A. Mazza, the president of Eternit Pietra Atrificiale S.P.A of Genoa, established a factory in 1907 to produce AC roofing material under the process invented by L.Hatschek. In 1911, Dr. Mazza started experimenting with the manufacturing of AC pipes and in 1916 production began on a commercial basis.

AC pipes were first introduced in North America in 1929 when Johns-Manville Corporation installed an AC pipe manufacturing machine (Hu et al. 2013). Problems with rust formation in galvanized steel led to the exploration of other pipe material, including AC pipes, for use in potable watermains during the 1940s, ’50s and ’60s.

However, due to health concerns asso14 | February 2020

ciated with their manufacturing process, and the possible resale of asbestos fibres from deteriorated pipes, AC pipes were largely discontinued in North America and their use was stopped in the 1980s.

Although they were discontinued in North America, a significant portion (an estimated 16% – 18%) of the water distribution system in North America is still made of them.

AC pipes can be classified into two categories, Type I and Type II. Type I contains 20% asbestos fibre and 80% Portland cement, cured under moist conditions. Type II steam autoclaved AC pipes differ from Type I pipes, in that 40% of the cement is replaced with silica that bonds with the free lime, producing a more stable product since it permits various hydrothermal reactions, in addition to the hydrolysis of cement (Bracken 2012; Hu et al. 2013).

AC PIPE FAILURE The failure of AC water mains is influenced by a number of factors that can be grouped into three categories (Hu and Hubble, 2007): • Physical characteristics of the pipes (e.g., pipe age, pipe size, manufacturing process); • The pipe location environment (e.g., climate, soil type and groundwater properties); and, • Operational characteristics (e.g., conveyed water quality and procedures for operation, maintenance, repair and replacement).

The interaction of these factors determines the deterioration processes and modes of failure for AC watermains.

Soft water with very low ion content (low carbonate and bicarbonate content) is aggressive to calcium hydroxide and results in the leaching of calcium hydroxide from AC pipe materials and a consequent reduction in mechanical strength. Key parameters for identifying aggressive water include low pH, low alkalinity, calcium hardness, and negative Langelier index.

Factors affecting external chemical attack are similar to those influencing internal attack (i.e., pH, alkalinity and sulphates contained in the soils or groundwater can damage AC pipe materials (Jarvis, 1998)). These chemical processes either leach out components of the cement material or penetrate the pipe wall to form products that weaken the cement matrix, reducing the structural integrity of the pipe, as well as affecting water quality.

In order to understand in-service failures, it is necessary to have knowledge of the pipe stresses and any degradation of mechanical performance with time.

Regardless of the source of the loading, for failure to occur, the stress level must

exceed the strength of the pipe material.

The relationship between the failure load of AC pipes and their in-service condition is defined in the combined load theory adopted by the ANSI/AWWA C401.

relies on a set of criteria that each pipe owner can develop to assess their AC pipe inventory.

As for the AC pipe scanner (ACPS) and ePulse inspection tools, the main difference is that the ACPS tool is an invasive AC PIPE ASSESSMENT METHODS inspection tool that requires the pipe to While the techniques available for be out of service. The ePulse is an extermetal pipe have advanced with the nal correlator concept that inspects the requirements of the oil and gas indus- pipe while it is still in service. Both tools tries, cementitious pipes used in the water and wastewater industries have not benefited from similar advancements. Currently, two well-established non-destructive technologies (NDT) are used for assessing AC pipes: ground penetrating radar or pipe penetrating radar, and acoustic measurements.

In addition to the NDT, there are assessment methods for assessing AC pipelines. These include hardness, phenolphthalein, pipe crushing/ bursting, and petrographic tests.

Tests are recommended on pipes extracted from a failed pipe segment.

However, a planned coupon sampling program may be utilized to provide a better understanding of the system condition at a selected location that represents the entire sounding environment for the water system (e.g., similar soil conditions, and/or similar surface load conditions).

NDT methods may be a preferable option, but none of the available assessment technologies can work in all conditions. Each has unique capabilities and advantages when compared to other condition assessment methods. Therefore, selecting technology for assessing watermains becomes an optimal process that INSTALLS UP

manage their assets and select suitable intervention actions that aim at maintaining, rehabilitating or replacing them.

The condition grading system is a valuable method used by asset management specialists to assign a numerical number from 1 to 5, based on a predefined program rating system.

While the standard practice of condition grading for the gravity pipelines industry is based on the National Association of Sewer Services Companies (NASSCO) methodology, the pressurized pipeline grading system does not have a similar standardized approach.

Rajani and Makar (2000) developed a methodology to estimate the remaining service life of grey cast iron mains. It considered the residual resistance capacity of grey cast iron pipelines, anticipated corrosion rates, and the measurement of corrosion pits to predict the remaining factor of safety (FoS). Despite this significant contribution, the present research is dedicated to evaluating grey cast iron only.

The methodology to use residual FoS was presented as a method that can be used by decision makers to describe pressurized pipe conditions using a numerical number (residual FoS). When calculating the residual FoS of AC watermain pipelines, imposed loads as per the ANSI/AWWA C401, along with the measured wall thickness information obtained via NDT assessment methods, must be considered.

The analysis is presented via a nondimensional condition grading curve generated for AC watermains that uses a condition rating system from 1 to 5, based on the residual FoS methodology. Since the rating is based on the residual FoS, each score from 1 to 5 is associated with a recommended intervention action based on the Guidance Manual for Managing Long Term Performance of AC Pipe (2013).

and imposed loads showed an acceptable condition (grade 2).

Relying only on thickness measurement may mean condemning pipe prematurely when it still has substantial strength that will allow additional service life. As long as there are no additional and/or new loads imposed on the pipe, periodic inspections using NDT assessment technology can be determined via estimating the time for the pipe stress status to reach condition grade 3 via linear deterioration estimation.

WASTEWATER

The right equipment helps WWTPs cope with the unknowns of septage receiving

By Christa Renouard

eptage systems that are appropriately designed and maintained provide an excellent form of localized wastewater treatment. If a system gets overloaded or is not on a regular schedule of service, then issues with contamination of surface or groundwater begin to emerge.

A critical component of the proper maintenance of a functioning septic system is to regularly clean and extract settled solids from the tank. However, disposal options for collected septic waste are narrowing to facilities that can handle and pretreat the wastes. Strict regulations and guidelines restrict landfill or land application without the material first undergoing some form of pretreatment.

Wastewater treatment plants provide a viable option to accept and process the collected septage. However, the sheer concentration of the transported sludge can potentially cause plant upsets in smaller facilities. Early strategies where septage was simply dumped in at the headworks, often overwhelmed the screen and caused problems downstream. The end result was many small plants choosing not to accept septage waste.

By creating a receiving area for hauler trucks to offload septage waste, it becomes practical to employ forms of pretreatment, monitoring and storage. This then allows the plant operations staff to control and meter extra loading to the plant. Systems like this can be automated, reducing the need for excessive operator attention. An accurate billing system can be employed through a keypad/card kiosk that combines the measured flow and monitored water quality parameters in the billing.

The advantage of this approach is that it opens up an opportunity to generate revenue, which offsets the investment and contributes to reducing overall operating expenses.

Grease collected from restaurants and food processes is a potential source of energy for digesters.

Grease traps also keep fats, oils and grease from clogging collection systems.

WHAT WAS ONCE A PROBLEM Similar to the evolution of handling septic wastes with the creation of septage receiving stations, this same receiving station technique can be modified to accept energy-rich waste grease from restaurants and processers. With early adoption of processes like co-generation, organics such as fats, oils and grease, were sought out to add to the digesters used in generating energy to offset operational costs.

This new approach instituted programs of point source collection techniques for early capture of the grease in localized traps. This also greatly aided in minimizing maintenance issues with grease clogging a municipality’s collection lines and lift stations as the wastes are transported to the wastewater treatment facility.

However, much like the early attempts with the acceptance of septage, grease has its own factors that affect the ease and practicality of accepting these wastes at the facility. One wastewater treatment plant experienced initial difficulty with the handling and processing of received

brown grease waste. The grease collection process was susceptible to people treating the collection bins as trash disposal.

The initial design of the receiving station utilized a bucket strainer, which required frequent manual cleaning that diverted operations personnel from essential plant duties. This manpower issue was easily resolved by incorporating a self-cleaning inline sludge screen. This configuration provided a robust technology that fits well into the automated system.

NOT WITHOUT CHALLENGES As a greater diversity of hauled wastes are being accepted into septage receiving stations, so too are the occurrences of unplanned material entering the system.

The industry has been served well by standardized septage receiving stations.

Many of these systems were designed to accommodate domestic septic tank waste from households, apartment complexes, resorts, etc.

Chemical toilets, or Porta-Potties, present a new challenge. Whereas the nature

of a conventional septic system’s waste characteristics minimizes exotic debris in hauled waste, Porta-Potties are a potential wild card. This type of portable chemical toilet provides a sanitary solution for almost any outdoor event. However, this also provides a portal for disposal of just about anything imaginable.

One wastewater treatment plant discovered firsthand what could be encountered with the introduction of waste from portable units. The first system was designed for traditional septage as well as grit.

After a series of large public events, there was a sizable influx of wastes brought in from the portable toilets. The receiving machines at the septage receiving station were quickly overwhelmed and disabled.

In troubleshooting, what had come in from several portable units around the area was examined. Everything was found in the septage, from knives, ammunition and power tools to clothing, syringes and electronic devices.

With a clear understanding of the nature of debris being encountered at the

facility, it was then possible to provide an addition at the station that could handle that type of waste without causing problems with the machinery. The solution was a centre feed drum type of machine that could handle the severe and unusual material brought in with the portable toilet wastes.

into a centralized complete grit treatment facility. This type of system handles, washes and classifies the raw material. As a result, the classified inorganic material (sand and gravel) can be recycled for clean fill or roadbed material. The organics can be retrieved for co-digestion purposes.

WATER While it is still early in this multi-year project (expected to conclude in 2021), initial successes have proven the mobile DMA testing concept and substantial value has already been realized.

Mobile unit deployment occurred over four nights at both full and reduced pressures.

Mobile district metered area testing helps cut watermain leak losses

By Bradley Jenks and Fabian Papa

T

he April 2019 issue of ES&E magazine featured an article titled “Municipalities wanted for new water loss testing project”, which introduced an Ontario-wide water loss testing project. In recognition of the synergy between water loss reduction and energy conservation, the cross-sectoral project, led by HydraTek & Associates, is supported primarily by the Independent Electricity System Operator (IESO) through its Grid Innovation Fund.

The study involves the development and deployment of a mobile testing unit designed to accurately and reliably measure minimum night flow (MNF) into specific sectors of water distribution systems, often referred to as district metered areas (DMAs). In addition to flow monitoring, the effectiveness of pressure reduction on flow (and leakage) reduction is 20 | February 2020

directly measured through the activation of a pressure reducing valve (PRV) within the mobile unit. The mobile unit has been assembled, tested and deployed at several locations in York Region and the City of Ottawa.

The project involves testing at 20 DMA sites across Ontario. Results are used in the development and application of evidence-based benchmarking metrics that can assess the performance of DMAs in municipalities across North America.

One of the key project objectives is to increase awareness surrounding water loss reduction practices. Reducing water losses also reduces needless energy consumption associated with water lifted to overcome elevation differences, moved through piping networks which offer frictional resistance, and pressurized to provide an adequate level of service to users.

A COMPELLING CASE FOR WATER LOSS REDUCTION PRACTICES Among the test sites thus far, of particular interest was a tested DMA located in a municipality that purchases its water at wholesale from upstream bulk suppliers. Consequently, the marginal cost of water to the municipality is rather high (relative to those municipalities that produce their own water) and at the current rate, which is trending upward. Therefore, any water loss reduction efforts would be justifiable.

From an energy perspective, the test site is situated relatively high in elevation and pressurized to operate at a hydraulic grade line approximately 155 metres above source water elevation. Furthermore, appreciable frictional losses are generated from the over 28 kilometres of transmission mains that connect the site to its supply.

Based on an average wire-to-water pumping energy consumption of 4,000 kWh/Mm3/m1, and accounting for static lift and dynamic frictional losses, the embedded pumping energy for the case study location is determined to be 0.734 kWh/m3. This is nearly double the average of the other tested DMAs. Accordingly, the selected test area is an ideal candidate to exhibit the benefits of possible energy conservation from reducing inefficiencies such as watermain leakage.

Understanding the considerable consequences to leakage in the area, the municipality had initially retained HydraTek to design and implement a permanent pressure management area (PMA). The goal was to curb pressure-dependent background losses in a sector of their watermain system, which consisted of old metallic pipe and suffered from higher-than-average history of breaks.

However, from an evidence-based perspective, no reliable site-specific data was available upon which to justify the appreciable investment of a PMA. All things considered, the characteristics and intervention intentions in the area demoncontinued overleaf…

STORMWATER

Finding the right stormwater management system for a mixed-use development in North Vancouver

By Peter Kumar

W

hen tasked with finding an efficient and compliant stormwater management system for a large multi-family mixed-use development in North Vancouver's Lynn Valley area, the developer enlisted the help of a local civil consulting firm. They, in turn, approached BARR Plastics Inc. for a durable solution that would not only protect the development against flooding, but would also work with the site's unique, tight and hilly profile.

It was also key for the system to meet the District of North Vancouver Hastings Creek Watershed Stormwater Report stringent storage volume requirement of 1,143 m3/Ha. The consultant and BARR Plastics specified, designed and supervised the installation of three stormwater infiltration systems, which were installed in two phases. During the first phase, a 1,180 m3 two-tank system was installed.

It was built using 5,760 heavy-duty EcoBloc Inspect Flex modules in order to meet a burial depth of 5 m, with in-built inspection channels for easy maintenance. During phase two,

a second, 658 m3 system was installed which consisted of 3,210 EcoBloc Inspect Flex modules.

Due to the hilly profile and minimal footprint available on site, the stormwater system needed to be deeper underground, with a 5 m burial depth and provide HS-25 loading. The solution was a three-tank system using Ecobloc Inspect Flex in combination with Vario 800 flex shafts. These were located to provide full access into the tanks for inspection and maintenance. The first tank required a minimum earth covering of just 560 mm, whereas the second and third ones needed a minimum cover of 2,000 mm.

Post-construction, the developer requested the temporary installation of two Liebherr LTM 1095.1 270 Ton and 120 Ton mobile cranes over the buried Ecobloc tanks to be used to dismantle the man hoist. Due to the consultant’s design providing vertical and lateral loading capacity of Ecobloc Inspect Flex, the design factor of the modules met the load requirements.

Personnel from the design consulting firm, BARR Plastics and a local geotechnical consulting firm worked together to approve the crane installations.

This system was built with enough capacity to resist the kind of extreme storm only likely to happen once in a 100-year period. There is also an additional 15% contingency buffer for climate change.

Protecting a northern mine leachate spillway with concrete canvas

By Ron Drewry, Phill Greer, Rebecca Spitzer and Chantal Lambert

oncrete Canvas is a new class of construction material called geosynthetic cementitious composite mats (GCCMs). It consists of a three-dimensional geosynthetic fibre matrix filled with a high early-strength cementitious powder mix that hardens on hydration to form a thin, durable, waterproof and low-carbon concrete layer. Essentially, it is concrete on a roll and allows concrete construction without the need for plant or mixing equipment.

Used for a wide range of erosion control applications, Concrete Canvas (CC) has numerous benefits that make it an attractive product. First, its low mass, low-carbon technology uses up to 95% less material than conventional concrete for many applications. Secondly, CC’s roll format makes it logistically easier to handle and easier to install than conventional concrete – you just unroll, place and add water. Thirdly, it can be installed rapidly at a rate of 200 m2/hour. This is up to 10 times faster than conventional concrete solutions.

Once hydrated, CC typically sets to 80% full-strength within 24 hours. Once at full strength, its climatic resistance and durability should provide in excess of 120 years of performance.

CC was used for two spillway erosion control lining projects recently completed at Eagle Gold Mine. This site is located in the Yukon, approximately 200 km from the Alaska border. It is subject to a seasonal temperature variance of +20° C to –30° C. The spillways are designed to convey any overtopped mine heap leachate in extreme weather conditions. The first is the main spillway that connects a heap leach pad to an events pond.

The second is an emergency spillway for the events pond. The 26 | February 2020

mine site is heavily monitored by Canadian regulators.

Poured concrete with an applied coating was considered as the protective liner, but discounted due to logistical and installation complexities. Concrete Canvas alleviated these concerns and was chosen for the projects. A total of 8,240 m2 of CC8 and CC13 was installed.

The main spillway is approximately 500 m long with profile sections of 5 – 8 m at a 7% – 15% gradient. In this spillway, CC8 (8 mm thickness) was used for fall sections of 7.5% and CC13 (13 mm thickness) was used where the fall of the section increased to 15%. Installation was completed per standard channel lining details: hydrated overlaps, Soudseal 250XF bead, SS screws at 200 mm centres, 100-150 mm overlap with a 1.3 m anchor trench (0.75 x 3) along either crest with ground pins. Intermediate fixings were not required.

The emergency spillway is approximately 140 m long with varying widths at a 50% gradient. It was lined exclusively with CC13 per the engineering specifications. Installation was done a little differently than the main spillway and included gripple rock anchors at fixings not less than 1.8 m centres along its main section. At the 90° corner, anchor centres were not less than 0.5 m apart.

The city retained the services of Chisholm, Fleming and Associates (CFA) to complete the design for replacement of an existing watermain with a new PVC one. The goal of the project was to replace an approximately two-kilometre section of badly deteriorated watermain along a busy arterial roadway in a densely developed, mixed-use urban area, with minimal disruptions to traffic, residents and the natural environment.

The 2,040 m length of 300 – 350 mm cast iron and ductile iron watermain, parts of which were over 70 years old, stretched between Jane Street and Keele Street along Major Mackenzie Drive West. It was experiencing a very high frequency of breaks, that caused severe disruptions to traffic as well as service to businesses and residences.

The $4.2 million project also included replacing 19 valve chambers, as well as hydrants and water-service connections.

The design was completed between April 2017 and March 2018. Construction took place between May and December 2018.

A CHALLENGING PROJECT SITE The project site was inherently challenging. Major Mackenzie Drive West is a four-lane urban arterial road, travelled by an average of over 40,000 vehicles daily. There are particularly high levels of traffic during morning and afternoon rush hours. There are two large shopping plazas on either side of the street at the west end of the project site and commercial development on the north side at the east end.

The majority of the roadway is fully built out, except where the roadway crosses the West Don River, which is one of two major tributaries to the Don River, and in a sensitive, protected natural area.

In addition, above and below ground, the corridor is congested with utilities.

There is overhead and buried electrical and telecommunications infrastructure, as well as buried gas mains on both sides of the street and sanitary and storm sewers.

PROJECT DRIVERS The project was completed as part of the city’s state-of-good-repair program,

but three significant factors contributed to the urgency of the replacement.

One was the increasing service demands created by development. Between 1996 and 2006, Vaughan was the fastest-growing municipality in Canada, with an 80% increase in its population during that period. A larger and more reliable water supply was needed to meet the already heavier domestic and commercial water demand and to allow for further development.

A second factor was reliability of the water supply, in particular for Canada’s Wonderland. It is a premier entertainment attraction and the largest theme park in Canada, with approximately 3.8 million visitors each year. It is the city’s largest customer in terms of annual water consumption.

The final factor was the planned construction of the Mackenzie Vaughan Hospital. This $1.6 billion, 350-bed facility, which is currently on track for completion in 2020, will be the city’s first hospital. A reliable, high-volume water supply to the 1.2 million square foot facility, expandable to 550 beds, is critical.

FINDING A FAST, LOW-IMPACT AND COST-EFFECTIVE SOLUTION The preferred alignment, agreed upon by the city and the Regional Municipality of York (which owns the road), included a new, upsized 400 mm PVC watermain running primarily within the eastbound

curb lane between Jane and Keele Streets.

It was determined that installation within the boulevards was not feasible because of the high degree of utility congestion. Consequently, it was agreed that the watermain would be installed by conventional opencut construction, except for the crossing at Jane Street, which would be installed by horizontal directional drilling (HDD).

Because of concerns about the impact of construction on an already congested traffic route, the city asked that CFA further explore the feasibility and benefits of using HDD across the entire limits of the

project. The only design stipulations were that all entry and exit pits had to be located outside of the roadway and that the pipe for the watermain had to be cast-iron-outside-diameter (CIOD) compliant, for compatibility with waterworks valves, appurtenances, and restraints and so that future repairs and service connections could be made without special fittings.

CIOD compliance eliminated high-density polyethylene (HDPE) pipe, as its diameter is measured as outside diameter, rather than as inside diameter, as continued overleaf…

INFRASTRUCTURE is the case for both cast iron and PVC pipes. Also, the fittings for HDPE pipe are different. As lockable PVC pipe is only available to a maximum diameter of 300 mm, the only pipe material that would meet the city’s requirements was 400 mm fusible PVC pipe (Class 235, DR18), which was supplied by IPEX. The project site was investigated to determine the feasibility of HDD construction through a geotechnical investigation, as well as a review of available laydown areas. The geotechnical investigation found very dense clayey silt till and sandy silt till, which are suitable for HDD and present relatively low risks of inadvertent fluid loss through hydraulic fracture (frac-out).

A review of the laydown areas confirmed that HDD was feasible for approximately half of the proposed watermain length, so the city authorized CFA to proceed with the detailed design.

The preferred alignment primarily within the roadway remained unchanged.

Careful planning identified specific loca-

tions where entry pits and exit shafts could be located within the boulevard, without impact on existing utilities, or within auxiliary turning lanes to minimize traffic disruption.

Open-cut installation was used as originally planned in the eastern half of the site. Here, HDD was not feasible given the number of houses and businesses fronting the street and the difficulties of laying out and fusing the pipe lengths without blocking driveways and entrances.

Location of the entry and exit pits took into consideration the minimum bending radius of 110 m of the 400 mm fusible PVC, so that the pipe could be laid out, fused and pulled within the boulevard. To avoid as much of the utility congestion as possible, the watermain was designed to sweep out into the roadway along the preferred alignment and then sweep back into the boulevard between each successive HDD section.

Maximum pull length of each HDD section was a function of the available area in the boulevard to fuse and lay-

out the pipe and the typical thrust/pull strengths of HDD drill rigs. The average length of each HDD section was approximately 300 m. This pull length meant smaller equipment could be used. Installation was completed using a Vermeer D 36x50 (II) with 36,000 lbs thrust/pull (16,330 kN).

Use of fusible rather than lockable PVC for the replacement meant a number of field conditions had to be taken into consideration, including the weather. The fusing process needed to be protected from rain, wind and dust and temperatures had to be above 4°C. Connections of the fusible pipe had to be completed by a certified licensee of the pipe manufacturer.

One of the most significant challenges of the design was finding laydown areas for the pipe. Additional effort was made during the design to minimize impacts on traffic, while ensuring constructability. Recommended entry and exit pits were identified on the contract drawings, even though the location of the pits is sometimes left to the contractor to deter-

mine in the field.

A complete subsurface utility engineering investigation was a priority, given the number of underground utilities and the age of the existing watermain. However, despite thorough information about the location of the watermain and other infrastructure, a break in the existing pipe occurred during drilling of a pilot bore, even with 3 m of clearance. An investigation into the break found that the ductile iron pipe was in very poor condition.

A construction schedule with extended working hours and alternating daytime and nighttime shifts shortened construction of the watermain installation by almost three months (a temporary noise by-law amendment allowed for this). The HDD work took place mostly during the day, given its limited impacts on the site. The open-cut sections were generally completed during the night shift, and the following day the watermain trench along the previously installed watermain was restored with asphalt. This meant the roadway could be reopened to traffic to

OUTCOMES By seeking to maximize the use of

trenchless construction throughout the project site, the city and CFA were able to realize significant additional project benefits.

To start, there was a major reduction in the overall impact of the project continued overleaf…

INFRASTRUCTURE on residents, businesses and road-users.

No property-access or service-disruption complaints were logged from any of the commercial or residential properties along sections of the replacement completed through HDD. Because the HDD construction work had no, or only minimal, impacts on traffic, it could take place during the day, eliminating complaints such as those about nighttime construction that arose along the open-cut sections.

As well, the HDD sections of the watermain were installed approximately 1.75 times faster than the open-cut sections. One 244 m section took only eight days to install using HDD, versus 14 days for a similar length through open-cut construction.

In addition, extensive use of HDD allowed the city to protect its investment in its existing infrastructure and preserve valuable natural features. There were no utility impacts or damage within the entire HDD section of the project and only minor disruption to sidewalks, the roadway and streetscaping. Because HDD allowed for

the installation of the new watermain directly over the existing one, space was conserved for additional infrastructure within the corridor. As well, there were no tree removals in either built-up or natural areas.

Since fusible PVC has no joints, the new watermain passed the hydrostatic pressure test with zero leakage on the first round of testing. Leaks that sometimes occur in a newly installed watermain that uses many joints and mechanical bends can be difficult to locate and repair. Also, they can significantly impact the construction schedule and delay the infrastructure being put into service.

Use of HDD also lowered the carbon footprint of the project in several ways.

Keeping construction out of the roadway as much as possible greatly minimized traffic delays, which in turn minimized traffic idling. What’s more, the carbon emissions and nonrenewable resources for the HDD section of the project were insignificant. In addition, by eliminating the need for large amounts of new

material, HDD significantly reduced the embodied-energy costs of the project.

All of these benefits were realized with little extra cost. The HDD sections were completed at a cost of $1,080/m as compared to $960/m through open-cut.

PROJECT LESSONS The project produced valuable benefits for the team, in the form of greater insight into how complex infrastructure-replacement projects with multiple stakeholders in highly developed project sites can be successfully realized.

Some of the takeaways of the project may be valuable for other utility owners and consultants. Extra upfront effort during the design to more accurately define the alignment and to locate entry and exit pits ensured the constructability of the design and reduced traffic impacts to zero for much of the HDD section.

A more-detailed-than-normal geotechnical investigation gave more information to the contractors for bidding, which helped reduce the cost of the construction. The initial plan for nine boreholes at 200 – 300 m spacing was augmented to 17 boreholes to tighten the spacing to 100 m and give a more thorough understanding of soil conditions.

All of the large, 150 – 200 mm service connections to businesses along the roadway were also completed through HDD to avoid the major traffic disruptions that would have resulted if the service crossings were installed by conventional open-cut construction. As a result of proactive and continuous communication with businesses, the contractor was able to use private property as the laydown and equipment area for each connection, with full cooperation from the property owners.

Consultation with HDD contractors during the design phase and with Direct Drilling Ltd., who completed the HDD installation, after construction gave valuable input and feedback to the team for this project and the next one.

WASTEWATER

Demographic reality catching up to WWtps

By James Des Cotes, Valera Saknenko and Stephanie Tran

F

or years, there have been predictions of the Canadian population aging and moving to retirement and the need for succession planning. Back in 2003, researchers from Statistics Canada noted that the rising wave of retirements in Canada’s labour force would reach a peak in the early 2020s (MacKenzie and Dryburgh, 2003). This future is now here.

In recent years, the number of senior water and wastewater operators retiring has increased. This is leaving a gap in knowledge regarding the operation and maintenance of water infrastructure, in particular treatment plants. This is becoming a trend at many wastewater treatment plants (WWTPs) in North America, where the rate of baby boomers retiring is outstripping the rate of recruitment of qualified people to fill their positions (Raney, 2019).

Between 2004 and 2011 the percentage of operators aged 51 and over increased from 29% to 42%. At the same time, the percentage of younger operators has decreased (OMBI, 2013).

Based on this trend, it is expected that this experience gap will continue to grow over the next decade.

Municipalities in Ontario are now encountering not only staff succession challenges, but also the cumulative effect of plant upgrades carried out over the past decades at WWTPs. For many, proper procedures may not have been captured in operating manuals and other documentation. This results in manuals and operating procedures that are not consistent with the current practice which is known to the seasoned operators who are about to retire. This knowledge gap can seriously hinder the ability of newcomers to be able to do their work properly.

To address these issues, one municipality in Ontario recently retained R.V. Anderson Associates Limited (RVA) to assist in

sampling and testing procedures review; process troubleshooting guide; operations training; and final documentation.

During the first phase, RVA conducted a comprehensive review of the existing processes and documentation at the plant, including drawings, plant operating data, process controls and manuals. This was only available in hard copy and some items were found to be outdated, incomplete or missing entirely. RVA acquired the missing documentation from equipment manufacturers and assembled a complete set of plant O&M manuals.

An electronic set of O&M manuals was also prepared for ease of access for all members of the operations group.

The next step in the project was an examination of the existing sampling, testing and operational procedures in place at the plant. An evaluation was conducted to ensure that the plant was recording sufficient information to not only meet regulatory requirements, but also to assist operators in their ability to properly operate and maintain the plant. It was discovered that, while the plant was meeting regulatory obligations, some information necessary to evaluate plant performance was missing.

Recommendations were made to the plant owner to start testing and recording parameters, such as sludge volumes and characteristics, flow measurements between each process train, and waste sludge flow rates. This would allow for a more comprehensive review of plant performance in the future.

Operational procedures for plant upsets were also considered.

A process troubleshooting guide was developed, which acts as a quick reference for operations staff in the event of an upset.

The guide included probable causes for each upset and procedures for addressing the issues. Recommendations were made for preventative measures to reduce the risk of each upset in the future. Topics covered by this manual included loss of flow, high effluent ammonia, cloudy effluent, solids washout and foaming.

Each item in the guide was detailed with probable causes, solutions to address the issue, and preventative methods. (Figure 1) Training of operations staff was the final focus for the project. As the main process system utilized at the plant is a proprietary process, the manufacturer was retained through their local supplier, to provide specialized review and training. RVA provided training for the other processes at the plant, including an overview of sampling and testing procedures and the troubleshooting guide.

Several half-day training sessions were held for operations staff. The operation of each system was discussed, with an emphasis on the purpose of each component and troubleshooting common problems. Training materials, including responses to operator questions, were compiled and provided to operations for future reference.

The end goal of this project was for operations staff to obtain a better understanding of the plant and to ensure continuity in operation. Through the work completed in this project, the treatment plant will continue to be properly operated.

Northern communities could benefit from renewable energy systems

ater and wastewater treatment plants, along with other community utilities, require a steady and reliable power source to provide resilience. Diesel power generation and heating has been the standard in remote and northern communities for many years. Most are off the main electrical power grid, which means that diesel fuel must be freighted to each community at substantial expense by truck, ship or even aircraft.

This form of electrical generation is fairly inefficient, and produces significant greenhouse gases. There is the noisy rumble of generators running continually and it is well known that the burning of diesel produces harmful formaldehyde, sulphur dioxide, mercury and black soot. Also, there are supply, environmental and reliability issues.

THE MOVE TO RENEWABLES Once a geothermal, biofuel, wind or solar power system with battery backup is installed, very little shipping of goods to site is required.

Chris Henderson is Executive Director of the non-profit Indigenous Clean Energy (ICE) Social Enterprise and has started the 20-20 Catalysts Program, which assists Canadian First Nation communities wanting to replace diesel. He says that Canada is on the cusp of a northern energy revolution. New investment is being committed to cleaner energy technologies in remote communities countrywide. However, he states the main problem well.

“The different cost curves of diesel and clean energy stack the cards against change for many small and cash-strapped communities, even if it could mean savings in the long run. Diesel generation requires only a modest up-front outlay of capital. However, 85% of the cost is in ongoing fuel purchases. Clean energy projects like small hydro, by contrast, require big capital expenditures upfront.

But, positive economic returns over the longer term, such as net revenue for decades ahead, often do not influence the short-term decision.”

There are still economic, regulatory and operational challenges with renewable energy systems, For example, the supply and demand of power needs to be balanced 24/7. Battery storage and other new technologies can assist in this task. A remote monitoring and trending system also aids in troubleshooting and operator training.

Many remote communities have started on the journey to replace sooty diesel with alternative energy, but help is needed along the way. Useful resources include The Clean Energy for Rural and Remote Communities program, which supports a suite of diverse projects across Canada to reduce the reliance of rural and remote communities on diesel fuel for heat and power. Another is the Atlas of Canada.

fuel to Paulatuk in the Northwest Territories because of early ice. This meant that more than half a million litres of diesel had to be flown into the community to keep the generators producing power.

The bill was close to $2 million. Air freight of fuel is common for some communities.

Diesel fuel spills happen from time to time and in the past were often unreported. It is estimated that more than 10 million liters of diesel has been spilled north of 55 degrees latitude. These incidents are costly, both environmentally and economically.

Several years ago in April, the diesel generator in Pangnirtung caught on fire.

The search for lower cost water sources in the Arctic

By Ken Johnson

T

he search continues for technology with lower costs for water systems in the far north. One of the primary areas of this search is decentralized (individual water and sewage treatment systems in each house) wastewater technology and water re-use technology. The use of decentralized wastewater treatment is not new, and in fact it has provided a low-cost way of treating wastewater for rural homes in the south since the 1940s.

Technical innovations of the past 25 years have facilitated the expansion of decentralized water and water re-use systems, and even advanced the use of this technology in the urban environment.

In the context of Canada’s far north, climate, ground conditions and community isolation create expensive problems for piped residential servicing. In the City of Yellowknife, development costs, including roads and drainage, are over $120,000 per lot. A study in 2001 suggested that a comparable development 38 | February 2020

cost for a water re-use system could be less than $70,000 per lot.

Considering that approximately 55%, or 10,000 litres, of the water used in a typical Yellowknife household each month is for laundry and flushing toilets, there is an opportunity to save money by treating and recycling it for these uses.

The Yellowknife study compared the cost over a 20-year period for a typical residential piped water and sewer system and for a water re-use system. It concluded that water re-use could save approximately 40% of the overall cost, with the most significant part of this cost reduction associated with the elimination of putting pipes in the ground.

Typical unit processes of a water re-use system considered for Yellowknife included a septic tank for primary treatment, a biofilter followed by a slow sand filter for secondary treatment, and ozonation for disinfection of the water before it is re-used. Implementing a water re-use system in a house would

incorporate changes to the plumbing and electrical systems, and the building structure. The most important part of the system was the plumbing, which had to ensure a separation of the drinking and non-drinking water supply systems.

Unfortunately, the Yellowknife initiative was not advanced beyond the conceptual design phase.

In the State of Alaska, more than 2,600 rural homes lack running water and sewage collection systems. Existing water and sanitation systems include centralized laundry locations called washeterias, central water points, individual wells and in-ground systems, water and sewer truck or trailer haul systems, and piped water and sewer systems.

All of these operate on a user-pay principle with no operating subsidies, which is contrary to the considerable operating subsidies provided to water and sanitation systems in the Canadian north.

Decentralized systems with individual wells and septic systems are already in use in certain regions of Alaska. These are helped by the favourable in situ soil conditions. Trailer haul systems are also used; these are a scaled down version of northern Canadian truck-haul systems.

Four-wheel all-terrain vehicles in the summer and snowmobiles in the winter pull specially designed trailer-mounted water or sewage containers.

Conventional, community-wide piped systems in Alaska are increasingly expensive to construct, maintain and replace.

The available capital funding cannot meet the demand for new systems and the rehabilitation of aging systems, which is estimated to cost close to $1.4 billion USD. As well, many communities cannot afford the high operation and maintenance costs associated with piped or haul systems.

These emerging realities prompted Alaska to embark on the Alaska Water and Sewer Challenge in 2013 to hire groups of specialists to develop and implement decentralized water and water re-use systems.

The process of selecting companies to do this work was unusual, because it did not include the typical “requests for proposal”. Instead, it asked for “expressions of interest”. The project also included

seed funding of approximately $1.5 million to pay the selected companies to research and develop a useable technology. Six companies, out of an initial 18 that applied in the initial phase, advanced to the competition’s second phase, which ended with the presentation of proposals in late 2015.

Phase three of the project was completed in 2017, with the development and testing of prototypes of the top three proposals from the second phase. The results of phase three were presented to the project’s steering committee. All three of the prototypes were tested, and the steering committee settled on the process technology that separates greywater from urine and feces with a dry toilet system. The only technology advancing is the prototype developed by the University of Alaska Anchorage.

Greywater from the kitchen sink, laundry, shower, and bathroom sink will be recycled and made available at these locations as wash water for uses other than drinking and cooking. Separating the waste sources into a wash water system and a dry toilet was judged to be a means of eliminating the addition of “black water” into the treatment process.

Work is underway to rollout the system with a number of pilot projects. One of the projects is a pilot test of dry separating toilets to evaluate how well it may be accepted by home owners. Another rollout for the pilot projects is the installation of a system in a student residential building at the University of Alaska in Anchorage, which will be a first step before rolling out into unserved communities.

The program’s current goal is a secure, safe source of at least 55 litres of running water per person, per day in a four-person household. Wastewater management is an integral part of the Alaska system design, along with its introduction into existing housing units.

In Canada, there is cautious optimism about the successful outcome of the Alaska Water and Sewer Challenge. Certainly, any successful technology may also have applications in northern and remote regions of Canada.

Cold water nitrification and cyanides removal for mining wastewaters

By Myriam De Ladurantaye-Noël, Caroline Dale and Marc Laliberté.

R

egulations in Canada are such that mines are generally not allowed to discharge water acutely toxic to specific species of fish such as the rainbow trout (Oncorhynchus mykiss), the fathead minnow (Pimephales promelas) or invertebrates such as Daphnia magna.

In addition, discharge limits are slowly being tightened due to increasing environmental concerns.

Treatment for the removal of metals, nitrogen such as ammonia, nitrate and nitrite, as well as cyanide compounds such as cyanide, cyanate and thiocyanate, is often required prior to discharge to meet regulatory standards. In addition, most mining sites possess waste rock stacks and tailings ponds, which contain contaminated water due to surface run-off.

This contaminated water can be stored in ponds in the cold for extended periods, thus requiring a robust water treatment plant capable of handling seasonal water temperature variations down to <5°C. Biological treatment has been used for

temperatures (<5 °C). Long-term results are now becoming available from fullscale installations.

THE MBBR PROCESS The moving bed biofilm reactor (MBBR) is a fixed-film biological treatment process, which utilizes a high-density polyethylene

carrier as biomass support. These carriers provide a highly protected surface area for biofilm development. They have a density slightly lower than water, and are continually moved using air in aerobic systems and mechanical mixing in anoxic systems.

Extensive studies were undertaken on municipal and industrial (mining) wastewater to demonstrate prolonged operation at low temperature (0.5 °C – 5 °C for three months) for nitrogen removal. Additional tests have been conducted for various mining sites to validate such efficiency, not only on nitrification, but also on biological cyanide compounds degradation and its impact on the mine effluent toxicity.

Nitrogen removal rates in a biofilm system have been shown during these studies to be highly dependent on temperature. Typically, the design of a biological treatment will be done on the lowest water temperature, to ensure that there is sufficient capacity to achieve treatment under the worst conditions. In Canadian mine operations, the minimum tem-

perature at which nitrogen removal is required will frequently be below 5°C. The chemical composition of a mining effluent will vary depending on the mining operations and the ore being processed. A full effluent characterization is therefore required prior to the design of the treatment plant. The main contaminants of concern to be addressed using a biological treatment are: Ammonium and nitrate – These are usually found in mining effluent when explosives such as ammonium nitrate fuel oil (ANFO) are used for blasting.

Cyanate (OCN-) – Cyanate comes from the detoxification process of the gold leaching process. This cyanide compound is not toxic to mammals and birds but is lethal to Daphnia magna. In a biological treatment, it is hydrolyzed to ammonium and bicarbonate.

Thiocyanate (SCN-) – Thiocyanate is the product of the reaction between cyanide and pyrite. It is not toxic at the concentration usually found in gold mine

effluent. It is easily biodegradable and results in the production of ammonium.

The biomass yield of the bacteria responsible for thiocyanate is low, but once the biomass is fully developed, it is very resistant and will dominate the biomass in the biological treatment. These bacteria are in strong competition with the nitrifying bacteria. Therefore, oxidation of thiocyanate becomes a priority upstream of any nitrification process as it will inhibit ammonium and nitrite removal.

In all cases, metal concentration must be addressed upstream as copper will inhibit biological treatment if present at a high enough concentration. If present, copper is usually removed using a physico-chemical process.

During the laboratory and pilot studies, it was demonstrated that the removal rates are controlled by regulating the concentration of dissolved oxygen, pH (by alkali dosage) and carbon dosage for the denitrification stage. The control of these three operating parameters led to higher removal rates in a well-established system. This allowed process performance to be maintained under a higher load or at a lower temperature.

Automation helps maintain water tank levels and prevent freezing in colder climates

By Alejandro Duque

T

here are many ways to store water in a distribution system and the control system is the key component to ensuring it is done right.

Common practice is to use different forms of hydraulic altitude water control valves which use different control pilots, depending on application, to measure the tank levels and maintain or adjust water storage levels.

The two key factors for water storage are to ensure the tank maintains the correct level and that there is water turnover to protect water quality. In colder climates, low tank turnover can lead to water freezing within it. Water in motion due to tank turnover is far less likely to freeze.

Freezing can cause the altitude water control valve to lose the capability to sense a full tank and therefore can cause overflows. Freezing can also cause structural concerns internally, as well as externally, with ice pressure expansion on rivets, and bolted or welded seams. The additional pressure of freezing can also lead to pipe breaks and cause leaks where corrosion has occurred.

In an ideal case, the altitude water control valve would control tank water level to the set maximum of a hydraulic control pilot. Following this, the altitude water control valve closes and then the distribution line is opened. This allows the tank to drain down to a satisfactory level, where enough water turnover has been accomplished, before the altitude water control valve opens again to fill the tank to the set maximum.

In a two-way altitude water control valve situation, the same is true, except distribution is through the same valve as the filling cycle. In this case, the altitude water control valve would still close when the maximum of hydraulic control pilot is met. However, it would then re-open when the differential pressure in the line is reversed, allowing water to 46â&#x20AC;&#x201A; |â&#x20AC;&#x201A; February 2020

Tank application example.

distribute in the opposite direction.

Ideal operation is not always easily achievable, as system characteristics can change continuously and affect the system. As system demand changes, so does the pressure in the system. It is not uncommon for the incoming pressure to an altitude water control valve to drop off.

Altitude water control valves operate off the differential pressure of the inlet of the valve to the tank level head pressure. Consideration needs to be taken to ensure that the inlet pressure of the altitude water control valve is always greater than the tank level head pressure.

If the system fails to have a greater inlet pressure, it essentially equalizes the inlet pressure of the altitude water control valve and tank level head pressure.

With zero differential pressure, the altitude water control valve will essentially sit floating open, trying to fill the tank but never reaching the maximum level setpoint. With zero differential pressure, the system is essentially sitting at a static flow and pressure. Therefore, no water will flow in or out of the tank which means there would be no tank turnover.

To fix this situation, the set maximum

of the hydraulic control pilot needs to be adjusted and set to the correct tank level.

Or, the system inlet pressure needs to be increased above the desired tank level maximum setpoint. Adjusting the hydraulic control pilot entails a site visit to adjust the set screw of the altitude water control valve. This can be quite cumbersome in remote sites when many adjustments are needed to facilitate system changes.

Increasing system inlet pressure entails either ramping up pumps in the system, or adjusting the feeder zone pressures higher.

Both situations add time and cost, and can also increase water loss and add strain on the system due to extra pressure. This could result in additional pipe breakages.

Many systems are moving towards full remote autonomy and control. Hydraulic altitude water control valves have controlled tank levels for many years, but now the same control can be done with control panels and instrumentation.

By switching out the hydraulic control pilots traditionally used to sense level, and instead using electronic tank level/ pressure switches, or sensors paired with a control panel, the level control process can be achieved electronically.

Environmental Science &â&#x20AC;&#x2C6;Engineering Magazine

The hydraulic water control valve still remains. However, there is no longer the need for a complex hydraulic pilot system as mentioned above. Just a simple single solenoid is needed.

Once automation control is installed, one of two operational sequences can be used to achieve the level control process. The first sequence entails using one level/pressure switch located at the maximum level setpoint and a secondary at the tank drawdown setpoint. If the water level is located below the tank drawdown switch, the panel will open the control valve via the solenoid and allow the tank to fill until the maximum level switch is contacted. The panel will then close the control valve using the solenoid.

This control valve will remain closed until the tank level is drawn again below the drawdown switch. Although this is an effective technique and provides more flexibility than the basic hydraulic altitude water control valve, the maximum level and drawdown switches are still sitting at a constant level. They would need to be adjusted accordingly on site to allow for variations of the setpoint, which is sometimes needed to adjust to system changing pressures.

A more versatile option is to use a level/ pressure transmitter. These are available in all shapes and forms to fit specific tanks and offer a 4-20mA feedback signal to the control panel that gives exact tank level. Having a live feedback signal allows the panel to offer up a lot more options in the way the tank level setpoints are set.

The level control panel can then offer a variable setpoint for both the maximum level and drawdown that can easily be changed via a user interface on the panel.

This eliminates the need for site visits to change any setpoints and allows the system’s setpoints to be changed as needed to ensure optimum operations.

The level control panel with touch panel (LCP-TP) interface designed by Singer Valve was created to accomplish optimum level control feasibility and flexibility. It is designed to complement a single solenoid operated/override control valve and 4-20mA level sensor or high/low level switches. This combination package works well for filling any kind of tank that requires filling to a level www.esemag.com @ESEMAG

setpoint and then drawing down the level of the tank to a secondary setpoint. It then activates the fill cycle again, ensuring water turnover.

The LCP-TP is quick and easy to configure to read and compare the level 4-20 mA signal to the desired setpoint. Setpoints can be set locally via an interactive button display screen or remotely via either SCADA Modbus or hardwired 4-20 mA remote setpoint signals. If a high/low level switch system is preferred, the LCP-TP can switch configuration to allow for level switch inputs and regulate the control valve accordingly. Data logging is also a useful feature to log sensor feedback and setpoint data with a time stamp, allowing for system analysis.

For the user who wants to set up a full communication network that has access to all storage tanks and controls them remotely, it is easy to do with Modbus and remote 4-20mA communication options.

For the user that has a remote site, but wants to be able to data log and analyze

the tank turnover, the LCP-TP offers the data logging feature.

Either option offers lots of feedback and traceability of the system operation.

Based on this information, the tank level setpoints can be adjusted to match the needs/demands of the system with simple interaction to ensure it can function optimally. The ability to take all the information and then easily adjust the tank setpoints is a huge benefit.

The LCP-TP itself does not eliminate tank turnover issues. Systems still need to be operated correctly. But having access to all the feedback information should allow insight into doing so. Alarm/notification means operators instantly know if something goes wrong with the system.

Procedures can then be set in motion right away to rectify the problem.

Addressing Iqaluit’s water emergency with innovative engineering, ecosystem protection

By Erica Bonhomme, Matt Follett and Arlen Foster

T

he City of Iqaluit is the capital of Nunavut and a thriving and growing Arctic community of approximately 8,000 residents, government offices and small to medium-sized businesses. Iqaluit obtains and distributes potable water to its residents and businesses from Lake Geraldine, an engineered reservoir located approximately one kilometre north of the city centre.

The reservoir is currently designed to provide water to a population of up to approximately 8,300 people.

Lake Geraldine is refilled annually during the open water season (spring to fall) by natural inflows from snowmelt and precipitation. Summer capacity of the reservoir is about 1.8 million m3. However,

or firefighting. The reservoir must be at full capacity at the onset of winter, to reduce the risk of potential water shortages during the cold months.

In the summer of 2018, after a dry winter and meagre spring runoff (freshet), it was predicted that the reservoir would not fill to full capacity naturally prior to the next winter. The Chief Medical Officer of Health identified the potential shortage of potable water as a public health emergency.

A short 2019 freshet and sealift delay began indicating that Iqaluit would be dealing with another emergency situation.

As the population of Iqaluit grows and as a result of aging infrastructure losses, water demand has been increasing. Each year, the city is at risk of an over-winter water shortage. As such, it has begun to study the feasibility of additional sources and storage of water, with the aim of implementing a permanent additional supply to Lake Geraldine by 2026.

consecutive year. Compounding the 2019 water shortage, flows in regional watersheds were at historic lows throughout summer, limiting what may have been a re-implementation of the 2018 solution.

THE SOLUTION Over a period of just several weeks in both 2018 and 2019, Nunami Stantec designed systems to supplement water from the Apex River watershed to Lake Geraldine. Despite the urgency of the situations, the design of water supplementation was carefully planned to protect the Arctic char of the Apex River and their habitat.

The designs directly used the geomorphology and hydrology of the local watersheds to optimize the use of equipment and water conveyance. In September 2018, just under 200,000 m3 of water was transferred from the Apex River to Lake Geraldine. This filled the reservoir to spillway elevation.

In 2019, approximately 460,000 m3 of water was transferred from Unnamed Lake to the Apex River, and 570,000 m3 were transferred from Apex River to Lake Geraldine in just over one month.

This filled the reservoir to within 15 cm of spillway elevation.

The dual sources used in the 2019 program required careful planning, consideration of complex logistics, specialized design, and close monitoring over the duration of the project.

2018 EMERGENCY RESUPPLY In 2018, while the environmental aspects of the challenge were being managed, the municipal engineering team of Nunami Stantec was active designing a pumping and piping system that would transfer the nominated volume of water to Lake Geraldine in the short remaining season.

The exercise required Nunami Stantec to complete the following tasks: • Evaluate route options from Apex River to Lake Geraldine and from Apex to an adjacent lake in the Geraldine watershed; • Prepare profiles of each route; • Evaluate the hydraulics of the most favourable routes to Lake Geraldine with a multiple set of 100 mm diameter hoses, which were available in Iqaluit (Government of Nunavut owned), with two possible submersible pumps; • Complete design for the pumping and piping schematic including Fisheries and Oceans Canada intake screen require-

ments, metering requirements, distribution manifold design, and options for arrangement of the available hoses to optimize transfer volumes.

The system design needed to ensure the transfer of up to 400,000 m3 of water in 60 days, pumping 20 hours per day.

The project team completed a pumping analysis and determined that it was possible to meet these requirements utilizing the available 100 mm firehose. They also determined that transfer of the required volume of water could be completed with Top: Hose distribution two Flygt BS-2201 submersible pumps. manifold at Unnamed Lake.

2019 EMERGENCY RESUPPLY The 2019 water supply project was based on sourcing from the Apex River, but there were some significant differences to the 2018 design. This water supply emergency was more complicated to resolve than in 2018 in several ways.

Firstly, water levels in Lake Geraldine were lower than in 2018. In fact, they were at historic lows due to the previously

noted low runoff in the spring of 2019.

This required doubling of the desired pump rate from 95 litres per second (2018) to 200 litres per second.

Secondly, as noted previously, the historic low flow levels in the Apex River prevented pumping at the required rate as it exceeded the DFO required minimum

river flows and maximum withdrawal rates. Otherwise the pumping rate would have taken all the water from the river.

Therefore, maintaining these minimum river flows to prevent harmful effects to fish, required transferring water from another source to increase the flow in the

Apex River. This was the Unnamed Lake.

In the early spring of 2019, before the status of the emergency was fully clear, Nunami Stantec had completed the design of the 300 mm HDPE piping and pumps system from Apex River to Lake Geraldine as a semi-permanent installation.

The new Sulzer J604 pumps were optimized for the final route and piping type.

Piping and pumps were sourced and shipped on the first sea lift to Iqaluit and were installed in the selected route from Apex to Geraldine in August 2019. By the time the 2019 water emergency was present, this new piping configuration was available for use. Due to the higher flow capacity of the 300 mm piping, the higher pump rate from Apex to Lake Geraldine was able to be accommodated.

To address the water transfer from Unnamed Lake, Nunami Stantec evaluated aerial photography and available digital terrain mapping, and selected a functional route from Unnamed Lake to the Apex River. This routing was longer than the Apex to Lake Geraldine route which would normally require additional pumping energy, but with a much lower head requirement due to differing elevations.

Numami Stantec repurposed the flexible hoses and manifolds used in 2018 and determined that it would be possible to pump water from Unnamed Lake directly into the Apex River. This would require different pumps and a secondary generator site. Both the Apex River and Unnamed Lake pumping systems were put into operation at the same time. Both functioned as designed, continuously pumping at rates of between 150 and 200 litres per second, for up to 24 hour per day, until Lake Geraldine was filled.

The final outcome of pumping from Unnamed Lake into the Apex River, and from the Apex River to Lake Geraldine, allowed Lake Geraldine to be brought up to the maximum full level prior to freeze up in September. Apex River maximum withdrawal and minimum thresholds were also met.

Scientific assessments of climate change in northern regions

By Ric Horobin and Xin Qiu

O

ften, the scientific assessment of climate change scenarios seems to be carried out separately from an assessment of the local impact that will be felt, and in many places is already being felt, as a result of a warming world.

This is particularly true in large parts of northern Canada that are warming faster than other parts of the planet.

The question around climate change is most often that of what we need to do to reduce emissions of greenhouse gases. That is an important question to ask. Less often is the question posed as to what we can do to try to solve some of the problems that already exist.

While this may be less of an existential question, it is still a question that needs addressing, because the impacts at a local level are sometimes several stages removed from the direct effect of a warming climate.

As an example of this, melting permafrost has the potential to release methane, a powerful greenhouse gas, into the atmosphere, further enhancing man-made climate change. However, the impact of melting permafrost is already being seen on ground engineering where foundations are no longer able to support build54â&#x20AC;&#x201A; |â&#x20AC;&#x201A; February 2020

ings and roads are damaged as a result of the changing ground conditions.

SLR Consulting have been working on this problem for several years now.

Dr. Xin Qiu has been modelling the likely impact of a warming climate on a variety of different issues, from mine tailings dam stability to the development of a new building code for Ontario. Dr. Ric Horobin has been developing engineering strategies to deal with the effects of a changing climate on ground stability and groundwater movement.

Climate models are based on well-documented physical processes to simulate the transfer of energy and materials through the atmospheric system. Climate models, also called general circulation models (GCMs), use mathematical equations to describe how energy and matter interact in different parts of the ocean, atmosphere and land. Establishing and running a climate model is a complex process of discovering and quantifying Earth system processes, representing them with mathematical equations, setting variables to represent initial conditions and subsequent changes in climate forcing, and repeatedly solving the equations using powerful supercomputers.

Once a climate model can perform well in hind-casting tests, its results for sim-

ulating future climate are also assumed to be valid. To project climate into the future, the climate forcing is set to change according to a possible future scenario.

Scenarios are possible stories about how quickly human populations will grow, how land will be used, how economies will evolve, and the atmospheric conditions (and, therefore, climate forcing) that would result for each storyline.

In 2013, climate scientists under the Intergovernmental Panel on Climate Change agreed upon a new set of climate forcing scenarios that focused on the level of greenhouse gases in the atmosphere in 2100. Collectively, these scenarios are known as representative concentration pathways or RCPs. Each RCP indicates the amount of climate forcing, expressed in Watts per square metre that would result from greenhouse gases in the atmosphere in 2100.

Around the world, different groups of scientists have built and run models to project future climate conditions under various scenarios for the next century.

The model results demonstrate that global temperatures will continue to increase, but show that human decisions and the behaviour we choose today will determine how dramatically climate will change in the future. The latest, internationally contributed GCMs and their output are organized by CMIP 5 and 6 (Coupled Model Intercomparison Project Phase 5 and 6 (ongoing)), under the World Climate Research Programme.

GCMs are the best tools for computing future temperature, wind and precipitation (or other climatological variables), but their limitations do not let them calculate local details for these quantities.

Teams of scientists around the world develop various climate downscaling to address the issues from GCMs. Based on these, downscaling makes use of systematic dependencies between local conditions and large-scale ambient phenomena, in addition to including information about the effect of the local geography on the local climate.

For example, the Pacific Climate Impacts Consortium and the Ontario Climate Data Portal provide practical information on the physical impacts of climate variability and change in Ontario, the

Environmental Science &â&#x20AC;&#x2C6;Engineering Magazine

Yukon, and the Pacific regions of Canada.

One of the primary effects of climate change is the disruption of the water cycle. Since so much of everyday life and planning is determined by hydrological systems, it is important to understand the impact that climate change is having (and will have) on water supplies, infrastructure, food and energy production.

Increased variability in precipitation and more extreme weather events caused by climate change can lead to longer periods of droughts and floods, which directly affect the availability of, and dependency on, surface and groundwater. In northern regions, climate change impact is much more significant.

Permafrost covers about 24% of the exposed landmass of the Northern Hemisphere – about 9 million square miles. It is found at high latitudes and high altitudes, mainly in Siberia, the Tibetan Plateau, Alaska, Northern Canada, Greenland, and parts of Scandinavia and Russia. The continental shelves below the Arctic Ocean, which were exposed during the last ice age, also contain permafrost.

However, polar and high-altitude regions are some of the most climate-sensitive places on the planet. The Arctic is warming twice as fast as the rest of the planet, at a rate of temperature change that has not been observed in at least the last 2,000 years, according to the National Oceanic and Atmospheric Administration. In 2016, annual average surface temperatures were 3.5°C warmer than they were at the start of the 20th century. Permafrost temperatures in the Arctic were the warmest ever recorded.

A good example of the real-world practicalities of a changing climate is the impact on ground engineering. A reduction in the effectiveness of building foundations has been seen in the northern cities, particularly in Russia. Buildings once considered stable are starting to subside as a result of melting permafrost.

This is not a new problem as can be seen from subsidence of historic buildings constructed in Dawson City, Yukon Territory.

Many new engineering projects are required to be designed to withstand the impact of climate change. Without a clear assessment of the link between the GCM outputs at a global level and the www.esemag.com @ESEMAG

impacts observed at a local level, designers often take a precautionary approach and over-design and hence over-engineer, with the resultant increase in cost and use of resources.

Another example that requires additional research is the field of water resources. In many parts of the world, glacial ice provides a slow release of long-term water storage during dry summer months. Without this store of water, river flows are reliant on annual snow melt and rainfall, both of which cannot necessarily be relied upon throughout the year. This results in rivers that are more prone to rapid rises and falls in their flow rate and, therefore, they are less reliable as a source of water for communities, towns and cities downstream.

This has been well documented in the Himalayas in northern India and Nepal, but there is also risk in parts of Canada where groundwater resources, which are used for water supply, are fed partly by river flow, which in turn relies on glacial

meltwater for its regular supply throughout the year. Recent research has shown that the depth to the water table can have a significant impact on heat fluxes across the land surface, which in turn suggests a strong linkage between the climate system and groundwater.

Physically-based, fully-integrated surface/subsurface models have only recently emerged and more research is needed in order to be able to adequately address the real and potential impacts.

Our role as scientists and engineers must be to advance not only understanding of the climate system at a global level, but to bring together experts from different areas in order to address the impacts, real and predicted, at a local level.

BIOSOLIDS

New Monitoring technologies enable biogas plants to optimize Their efficiency

By Antti Heikkila

W

aste management presents a significant challenge to communities, with wastes increasingly being viewed as resources.

Organic wastes are a particular concern because of their potential to produce methane, a powerful greenhouse gas. However, the gases from the anaerobic digestion of organic wastes can be contained and utilized as a source of renewable energy.

Combustion of the gas produces renewable heat, or, in a combined heat and power (CHP) engine, it produces both electricity and heat. Biogas can also be upgraded to biomethane (>99% methane) for compression and injection into the natural gas grid or for use as a transport fuel. Anaerobic digestion plant operators can also generate income by exporting electricity to the grid, by selling heat or biogas to local businesses or communities, and by charging a gate fee for incoming waste materials. The digestate produced by such plants is rich in nutrients and can be used as a soil fertilizer and conditioner.

Regardless of the process, all plants need to optimize biogas production, while minimizing costs, waste and down time.

However, biogas is corrosive and potentially explosive, so in the past it has not been possible to conduct in-line monitoring. Until recently, the only solution has been to extract samples for analysis outside of the process.

Seeking to enable effective process optimization, Vaisala developed the MGP261, an in situ biogas monitoring instrument, for the simultaneous measurement of methane, carbon dioxide and humidity.

It is Ex certified up to Zone 0/1, which enables in-line installation in pipes and ducts where explosive atmospheres exist, with the area surrounding the pipes classified as Zone 1.

Installing a MGP261, an in situ biogas monitoring instrument.

ent groups of bacteria, and a key feature of effective biogas process optimization is the maintenance of a healthy balance of these microorganisms. The four main processes are: Hydrolysis – Complex organic matter such as proteins, carbohydrates and fats are broken down by bacterial enzymes into sugars, fatty acids and amino acids.

Acidogenesis – Various fermentation reactions convert larger molecules into organic acids, alcohols, ammonia, carbon dioxide, hydrogen and hydrogen sulfide.

Acetogenesis – Fermented products are oxidized into simpler forms such as acetate and carbon dioxide.

Methanogenesis – Archaea (single cell organisms) convert hydrogen and acetic acid into methane and carbon dioxide.

Any disruption to the last two processes will result in a lowering of biogas yield and can be detected by changes in the methane to carbon dioxide ratio. Hence, the requirement for continuous monitoring.

PROCESS MONITORING FOR IMPROVED EFFICIENCY ANAEROBIC DIGESTION Four main processes take place inside Biogas is typically 50% – 75% methane, the digester to produce biogas. All of with the majority of the remainder being these processes are mediated by differ- carbon dioxide and water vapour, with

small amounts of other gases. By monitoring methane it is possible to measure the successful operation of the plant. By monitoring the methane to carbon dioxide ratio, the plant operator is provided with a continuous real-time indicator of digester behaviour and the status of the digester’s microorganisms.

Data on methane and carbon dioxide can be used in a number of ways. It can be used by the operator to adjust loading rate and feedstock type if possible, in order to improve the status of the bacteria. Where the biogas is being used by an engine, the measurements can be used to optimize engine performance. Where it is being refined for injection into the grid, the data can be used to inform the biomethane upgrading process.

Of course, it is also possible to extract samples from the reactor for subsequent laboratory analysis. This can provide an accurate indication of process conditions, but the delay (and cost) of doing so means that timely or automatic action to optimize the process is not possible.

In-line monitoring of biogas methane and carbon dioxide helps to reduce the requirement for laboratory analysis. continued overleaf…

REINVENTING THE CHEMICAL DOSING SYSTEM The DICE Dosing Module, by Meunier Technologies, integrates all the necessary discharge components required for a typical chemical dosing system.

The block type design allows for a rigid, compact and reliable product, and the significantly reduced number of connections greatly decreases leakage potential.

The module allows for better precision and protection in the dosing system, and also features great quality due to its machined fabrication.

The Dosing Module overcomes the many fundamental problems of the current piping system design: • Poor quality of the piping connections; • Many potential leakage points; and • Excessive vibration caused by the pump pulsation – which leads to mechanical fatigue on connections and components.

Other features include: • Integrated: ° Ball valves for outlet, calibration column, and drainage; ° Auxiliary ports: pulsation dampener, washing port, transport/dilution water and secondary pumps; ° Adjustable back pressure valve; ° Adjustable pressure relief valve; ° Pressure gauge with isolator; and ° Standard design that fits all your essential needs.

• Extensive reliability and durability; • No threaded or glued connections; • Extremely compact design resulting in minimal footprint; • With only 3 supporting bolts and 4 connections, the module can easily be installed on new and existing systems (retrofit); • Possibility of having only 1 Dosing module for 3 pumps (1 injection point, 3 pumps); and • Capability of calibrating the pump with the correct suction head and discharge pressure.

BIOSOLIDS WHY MONITOR BIOGAS HUMIDITY? Humidity in biogas represents a potential problem for a number of reasons.

Humidity in gas may condense with changing pressure or temperature, in the pressure regulator or in transfer pipes, for example. Such condensation can cause serious damage and must be avoided.

Similarly, excessive humidity in biogas fed to the CHP engine increases moisture in engine oil and results in a need to replace engine oil more frequently.

Obviously, engine downtime for service maintenance or repairs should be minimized because this may result in flaring which can reduce revenue.

Humidity is also a serious consideration in the operation of activated carbon filters, because they are designed to work within specific humidity ranges.

Carbon filters are commonplace because biogas impurities such as hydrogen sulfide, siloxanes and a range of other organic gases need to be removed to prevent damage to the engine, or to generate biomethane of sufficient purity to

be suitable for gas-to-grid applications.

Excessive humidity causes carbon filters to wear out prematurely, resulting in a costly requirement for refilling. Some plants need to change them several times a year. However, too little humidity can also be a problem for some filters, resulting in the inefficient operation of the carbon filter.

WHY MEASURE IN SITU? In the past, the only option was to employ biogas analyzers which extract a sample for subsequent measurement by electrochemical or fixed wavelength infrared instruments. These technologies require frequent recalibration, which can be costly, labour-intensive, and potentially harm the plant’s capability to monitor continuously. Pumps and gas tubing are required and it is necessary to dry the sample to prevent the errors and potential damage incurred by condensation. These instruments are therefore unable to measure sample humidity.

This also means that the measure-

ments from extractive instruments are given on a dry basis. Such readings, by definition, will be higher than those from an in situ probe measuring on a wet basis. Vaisala’s MGP261 can provide measurements on either basis.

Sample extraction in cold climates also risks freezing of the sample line, which inhibits flow and leads to erroneous data. This problem could be rectified by trace heated lines, but they are expensive.

SUMMARY Effective biogas process optimization requires in situ monitoring of the key parameters, methane, carbon dioxide and humidity. Monitoring technology can help derive more value from waste, improve the profitability of biogas plants, help reduce waste, lower greenhouse gas emissions and recycle agricultural nutrients.

Cloud-based alarm and monitoring systems cut costs, while improving productivity

F

acing tremendous growth, one town’s water and wastewater system had to prepare to support new residents and businesses, while keeping costs in check. Its current system serves 1,670 sewer-use customers across approximately 47 square kilometres, providing 2.08 – 2.3 million litres per day (MLD) of wastewater treatment through its network of eight lift stations, and another 0.83 MLD at a water booster station.

The town recently approved building 890 new homes within town limits, plus the possibility of an additional 1,200 homes in adjacent areas, all of which are to be served by its water/wastewater department. To support this growth, the community plans to build an additional four pump stations in the coming years.

Analyzing heating requirements for mesophilic and thermophilic biosolids digestion

By Ivan Drako

S Primary digesters at Toronto’s Ashbridges Bay Treatment Plant, which were used for comparative analysis of heating energy demand for mesophilic and thermophilic anaerobic digestion.

60 | February 2020

tabilization of organic materials and biosolids, primary clarifier raw sludge and waste activated sludge that are generated at wastewater treatment plants, is achieved mainly in anaerobic digesters that use suspended-growth treatment processes.

The main objective of stabilization is to reduce the volume of solids for disposal, make the digested sludge less odorous and putrescible and reduce the content of pathogenic organisms and helminths (parasitic worms).

Anaerobic digestion (AD) occurs through several sequential biochemical reactions, including hydrolysis, acidogenesis, acetogeneses and methanogenesis.

The product of each reaction depends on the previous biochemical reaction prod-

ucts and process conditions, including substrate composition, temperature and pH. Based on the temperature range maintained during organic material stabilization and the present biological community (groups of anaerobic microorganisms involved in the process), anaerobic digestion may operate under mesophilic (30°C – 38°C) or thermophilic (49°C – 57°C) temperatures.

For referenced anaerobic digestion operation temperatures and established opinion on the process energy demand for AD reactor heating, the mesophilic AD is widely used, in most cases because of its supposedly lower demand for anaerobic digestion heating and better stabilization. This opinion is inconclusive and is qualitative, rather than quantitative, due to lack of comprehensive data or explicit analysis.

The objective of this article is to compare the heating requirements of both mesophilic and thermophilic anaerobic digestion operating modes and provide some analysis and conclusions based on the results.

Key features of both anaerobic digestion modes are provided in Table 1. This data will be used for the analysis and discussion that follows.

MESOPHILIC AND THERMOPHILIC ANAEROBIC DIGESTION REACTORS For the comparative analysis of mesophilic and thermophilic anaerobic digestion, we will use a reactor with a fixed concrete roof and conical floor slab, 33.5 m diameter, 10.8 m operating water depth, and 12.2 m side wall height. The above grade wall height and below grade wall depth of the digester structure is approximately equal. The above grade structure is a thermally insulated structure. Its below grade structure has thermal insulation between the structure and the soil installed to the frost line depth only. There is no insulation in the deeper digester wall section, or beneath the base slab. Total operation volume is 9,840 m3.

Biochemical reaction rates increase with increased temperatures. This is in accordance with the Arrhenius relationship whereby the process rate is increased 1.5 times for each 10°C temperature rise.

Therefore, thermophilic anaerobic digeswww.esemag.com @ESEMAG

tion is faster than mesophilic AD for the same or greater volatile solids (VS) reduction. As the operating temperature is increased, the minimum mean cell residence time is reduced significantly. This means that, at a higher temperature, the system can be operated at lower mean cell residence and hydraulic retention times.

Also, a smaller reactor volume can be used.

Based on this precondition, for the

comparative analysis, a reactor having a smaller reactor volume, two-time smaller operation volume of 4,920 m3, is also reviewed as a thermophilic anaerobic digester (called further as “50% Volume”).

The reactor has a similar operational characteristic (digested sludge volume by process time combination effect) as the mesophilic AD reactor of the 9,840 continued overleaf…

m3 volume. It has the following physical dimensions: 26.6 m diameter, 8.6 m operating water depth, and 10.1 m side wall height. The roof and floor construction, thermal insulation and installation conditions are the same as the digester reactor described previously.

For the comparative analysis, some applied assumptions are summarized in Table 2.

ANALYTICAL RESULTS Thermodynamic analyses conducted on the digester structure to calculate heat losses for each season’s temperature, anaerobic digestion mode and reactor size are presented as sludge temperature rises that should be provided in the heat exchanger to compensate for the outward heat dissipation through the digester structure and piping over time as shown in Figure 1.

Hourly heat requirements to support digestion for each season’s temperature, anaerobic digestion mode and reactor size are presented in Figure 2. Heat energy demand required to digest one m3 of sludge within the respective digestion period (HRT) for each season’s temperature, anaerobic digestion mode and reactor size are presented in Figure 3.

The heat loss balance of a digester is affected also by the addition of raw primary sludge and total waste activated sludge (TWAS) that may take place one or two times per day. The added “fresh” sludge quantity is usually limited to some pre-assigned volume in order not to upset the digestion process.

Figure 4 shows the estimated digester sludge temperature drop when the quantity of the added sludge varies from 1% to 6 % of the total digester operation volume. As a conservative approach, it was assumed that the average temperature of raw primary sludge is +15°C and that the sludge is added as one slug to the digester and instantaneously mixed.

For our case, the volume of the added sludge would be 1.5% and 3% and the temperature drop would be around 0.30°C and 0.65°C for mesophilic and thermophilic AD, respectively. These temperature drops appear to be less than the tolerated temperature ranges referenced in Table 1. Therefore, the digestion process would not be compromised.

Analytical Results Thermodynamic analyses conducted on the digester structure to calculate heat losses for each season’s temperature, anaerobic digestion mode and reactor size are presented as sludge temperature rises that should be provided in the heat exchanger to compensate for the outward heat dissipation through the digester structure and piping over time, Fig 1.

DISCUSSIONS AND CONCLUSIONS Desktop analyses to review the heating energy demand associated with mesophilic and thermophilic anaerobic digestion modes have led to several conclusions and recommendations.

Thermodynamic analyses conducted on the digester structure to estimate heat losses associated with the two reviewed digestion modes have shown that instantaneous sludge temperature rises maintained in the heat exchanger (Figure 1) and hourly heat requirements (Figure 2) are greater for a thermophilic digester rather than for a mesophilic digester, while both have equal physical dimensions and volume.

Thermophilic anaerobic digestion carried out in a two-time smaller reactor than a mesophilic digester has comparable temperature rises and hourly heat losses as in the mesophilic digester.

Heat demand required to digest one m3 of primary sludge within the respective digestion period (HRT) is greater for mesophilic anaerobic digestion due to a longer HRT than the thermophilic anaerobic digestion HRT. The average heat requirement difference is around 25% for equal volume reactors and around 100% for a two-time smaller reactor, “50% Volume” (Figure 3).

Addition of raw primary sludge and TWAS to an operating digester and the following temperature drops are below the tolerable temperature fluctuation for each anaerobic digestion mode.

Organic material reduction and methane gas production is greater for the thermophilic anaerobic digestion mode than for the mesophilic anaerobic digestion mode at 25% and 50%, respectively. As a result, the calorific value of

Temperature Drop in Digester, degrees C

The heat loss balance of a digester is affected also by the addition of raw primary sludge and total 1.50 waste activated sludge (TWAS) that may take place 1 or 2 times per day. The added “fresh” sludge quantity is usually limited to some pre-assigned volume in order not to upset the digestion process.

Fig.4 shows the estimated digester sludge temperature drop when the quantity of the added sludge 1.25 varies from 1 to 6 % of the total digester operation volume. As a conservative approach, it was assumed that the average temperature of raw primary sludge is +15 deg. C and the sludge is added as one slug 1.00to the digester and instantaneously mixed. For our case the volume of the added sludge would be 1.5% and 3% and the temperature drop would be around 0.30 and 0.65 deg. C for Mesophilic and Thermophilic AD, respectively. These temperature drops appear to be less than 0.75 temperature ranges referenced in Table 1 and, therefore, the digestion process would the tolerated not be compromised.

the organic material reduction yield is greater for the thermophilic anaerobic digestion rather than for its mesophilic counterpart at approximately 50% per 1 kg of reduced volatile solids.

Conducted comparative analysis has demonstrated that the overall heating requirement of thermophilic digestion, mostly due to the shorter HRT, is lower in the long run as compared with the heating requirement associated with mesophilic digestion. Greater reduction of organic material in the thermophilic digestion results in greater methane yield (calorific value surplus as compared with the mesophilic anaerobic digestion). This calorific surplus is a benefit in favour of the thermophilic digestion application.

SPECIAL FOCUS: COLD CLIMATES AND REMOTE LOCATIONS

The treatment process uses cartridge filters, followed by UV and chlorine gas disinfection.

Dawson City’s new water plant designed with resilience in mind

By Matthew Lozie

H

ome of the Yukon Gold Rush, Dawson City is a community of less than 2,000 people, However, this nearly doubles in population during the summer tourist season. The city offers a look into the past as it continually tries to maintain the original look and feel of its Klondike era.

The city provides residents with drinking water from four wells located near the adjacent Yukon River. Its existing water treatment plant was dated, cramped and did not meet the Canadian Drinking Water Quality Guidelines for well water.

During the conceptual design stage, it was determined that a new treatment plant was required. Several locations were identified for a new facility.

The Yukon Government retained Associated Engineering to provide design and construction services for the new Greenfield water treatment plant. Together with Yukon-based Kobayashi + Zedda Architects, Associated Engineering provided a preliminary design for the plant, to be situated on two adjacent city lots along the prominent 5th Avenue.

66 | February 2020

timber panels for the roof structure were selected due to constructability restraints in this remote community.

Design of all the facility’s components considered the cold climate environment.

Insulated high density polyethylene (HDPE) material was used for the extensive civil piping outside the water treatment plant, and heat tracing was used for aboveground piping.

Four different forms of energy provide power and heat to the plant. Treated water for distribution requires heating and the pipes are looped back into the plant from the distribution system to provide constant movement through the system to prevent freezing. Water is heated by a set of oil-fired boilers, as well as a heat exchanger that draws heat from the local biomass plant through an underground heating loop.

A solar photovoltaic system was added to the roof of the plant which will be used mainly in the spring and summer, making use of the extended daylight hours to supplement the building power requirements provided by Yukon Energy service.

A variable speed fire pump was selected to reduce the building and backup generator sizes and maintain even water service pressure in case of a fire.

Water treatment technology consists of cartridge filters followed by ultraviolet (UV) and chlorine gas disinfection.

Alternative filtration was considered, but cartridge filters were selected due to the high quality of the well water and the simplicity in operation of the system. Particle distribution analysis and total suspended solids analysis of treated water showed that cartridge filters provide appropriate treatment.

Associated Engineering created a building information modeling (BIM) model of the plant using Revit and AutoPlant that helped operations staff to visualize the plant and provide feedback.

Construction of the 6 million litres per day plant started in May 2018 and was completed in December 2019 at a cost of $13 million.

In keeping with the city’s historic setting, the design of the facility had to remain authentic to the gold rush theme. The Heritage Advisory Committee conducts a rigorous review of all new buildings in Dawson City. Initially, several building representations were proposed, including a boomtown store front. Through the consultation phase, it was decided that the building exterior would be a replica of an early 1900s cold storage building. The facade features a board and batten siding with a prominent front peak, narrow windows and a spiral staircase.

During design, several unique challenges were encountered. Due to the location of the city in a valley next to a river that is prone to ice damming and flooding, flood damage prevention was an important consideration, as well as the impact of climate change. To improve the facility’s flood and climate resilience, major electrical and controls equipment were placed on the second story of the building.
