“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. The Flottweg centrifuges also produce cleaner and more consistent centrate.”

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.

attendees. Due to the Canada/U.S. land border being closed at the time, and COVID-19 testing protocols adding substantially to the cost of air travel, the number of Canadians attending was very low.This year, attendance and the number of exhibitors are expected to be higher and hopefully, we will see more fellow Canadians.AsIfound out back in 1987, these events truly reveal the scale and importance of the wastewater sector, especially to young professionals. Come and visit our booth at the Ontario Government Pavilion. For more information on WEFTEC, visit: www.weftec.org Steve Davey is the editor and publisher of ES&E Magazine.

Shama Hyder, an award-winning brand strategist, global speaker and bestselling author, will provide the keynote address. She will share her insights on how modern communications, marketing and branding are more important than ever for the water sector. As the water sector seeks to keep ratepayers updated on new developments, maintain a positive reputation in the public eye, and engage with a complex digital information ecosystem, Hyder’s keynote address will provide insights from an outsider’s perspective. From cybersecurity threats to ever-changing regulations, the water sector faces issues that can be difficult to explain to others in their field — let alone to the public. “The water sector is grappling with issues that are challenging to communicate about, such as rate increases, PFAS, and biosolids,” Eichenberger says. “Shama will discuss the need for water utilities and companies to use branding and marketing to engage with stakeholders.”
One highlight of attending was the first annual Great Canadian Icebreaker, which went on to be held annually, until 2020 when the COVID-19 pandemic forced the cancellation of everything. After a three-year hiatus, the Great Canadian Icebreaker is scheduled to be held at WEFTEC 2022 at the Crescent City Brew house in New Orleans on October 9. www.weao.org for more details. WEF President Jamie Eichenberger will welcome the audience to the opening general session of WEFTEC 2022. He will also discuss the direction of the water sector and WEF’s role in its advancement, and why this year’s keynote is focusing on communications and“Itmarketing.isessential that the water industry provide information and tell its story,” Eichenberger says. “It is encouraging to see many water utilities and companies working to connect with customers and communities more proactively.”
Participating teams, including several from Canada, will compete to earn the highest score in five different events. Each team includes four members and often a coach as well. Each event is designed to test the diverse skills required for the operation and maintenance of water resource recovery facilities, collection systems, and laboratories. The five events are collections systems, laboratory, process control, maintenance and safety. Last year I attended WEFTEC in Chicago, which had a total of 9,250

Direct potable reuse provides only an engineered barrier between wastewater and potable water. This utilizes treatment technologies, primarily membrane-based, to act as a barrier between the potential for pathogens in a wastewater outlet, and the distributed product of engineered water treatment.
Treatment technology is equally as essential. Effective, userfriendly, and accessible treatment techniques are crucial to provide clean water resources to those without (over 2 billion people).There are two primary methods of supplying recycled water from wastewater treatment outlet to drinking water inlet. These are indirect potable reuse (IPR) and direct potable reuse (DPR).Indirect potable reuse provides a natural boundary between wastewater and potable water, such as a river, lake or natural water body where the treated wastewater can be diluted with naturally occurring water. Alternatively, treated wastewater can be pumped underground where it can be environmentally degraded by passage through soil, before mingling with natu rally occurring groundwater, and is then pumped to the sur face and reused as potable water.
Environmental Science & Engineering Magazine8 | August 2022 WATER REUSE
In either mode of wastewater recycling, the generally accepted treatment train is the same. For a host of reasons, water recycled via IPR is more generally accepted over DPR. Including a buffer of the natural environment between waste water and potable water is seen as a more palatable solution to the end consumer, even if the water quality in either mode is the same. However, water scarcity is driving communities to now consider DPR as a treatment methodology. To ensure maximum pathogen removal between wastewater and potable water, regardless of delivery route, the treatment train is likely to employ ultra-filtration (UF), reverse osmosis
Water should not be judged by its history, but by its quality
A mong the many hot topics related to our global envi ronmental zeitgeist, access to safe and clean drinking water is potentially the least divisive and most agreed upon topic. According to the United Nations, water is a basic human right, which “entitles everyone to have access to sufficient, safe, acceptable, physically accessible and afford ableThewater.”challenge of accessing safe drinking water is not simply limited to countries with drought or water scarcity, but is in fact a global issue. With water as a finite resource, reusing and recycling is con sidered a valuable and efficient strategy to reduce the intake of fresh water, provide alternative water resources, and extend the usability of our limited water sources. Population growth and global warming are constantly increasing the need for safe water, necessitating better public education regarding water scarcity and recycling water for reuse, including for drinking purposes.Reusing and recycling of water resources are natural parts of the water life cycle. You might have heard that “there’s a very high chance the water in your glass is what thirsty dino saurs were gulping ~65 million years ago” but neglected to think about that water becoming dinosaur waste. This waste/ resource cycle continues on and on. Water should therefore not be judged by its history, but by its quality. While raw water has a history, clean water does not. Building capacity through innovative and comprehensive cultural training is an essential step towards cultivating strong belief in the safety and purity of recycled water to drink. Sin gapore is a successful example of the planning and implemen tation of such cultural support and training programs in a socially diverse and multicultural population.
While it is common knowledge that water is a critical resource and too precious to waste, it is wasted none-the-less. A strong water infrastructure for all requires investment in modern treatment technologies, both large-scale and smallscale, and a smart, educated populace behind them. If we are smart about our water use, there is certainly enough for all.

There is no widespread, accepted credit requirement that is applicable across all jurisdictions. But, based on development in California, along with other regions in the U.S., consensus is trending towards a requirement to show 10-12 log removal of pathogens through the engineered barrier. This is techno logically achievable with the treatment train of UF-RO-AO. These technologies are definitively “space age”. As water on the International Space Station (ISS) is mission critical, wash water and urine on one day can easily become your coffee on the next. In a video produced by the Canadian Space Agency, ISS Commander Chris Hadfield stated: “Before you cringe at the thought of drinking your leftover wash water and urine, keep in mind that the water that we end up with is purer than most of the water that you drink at home.”
(RO), and advanced oxidation (AO). It is expected that a wastewater stream that is to be reclaimed for potable reuse will undergo a minimum of primary and sec ondary treatment. In many cases, it will also undergo tertiary treatment. This means that the wastewater being sent for pota ble reuse treatment will already be of high quality. Neverthe less, there is an understanding that all the barriers in treatment must be supplemented before the water will be acceptable as potable.UFis employed first. The primary goal of the UF step is to remove suspended material and provide a quantifiable bar rier to pathogens. Because UF treatment has been advanced to include a verification step to its pathogen removal, UF is included secondarily to guarantee credit for pathogen removal. RO is applied second. The RO step is the chief purification step of the entire treatment train. By employing high rejection RO membranes, nearly all the dissolved components in water can be largely removed or reduced to inconsequential levels. RO is also an absolute barrier to pathogens, as the transport of water from one side of the membrane to the other is not based on a quantifiable pore size. Barring an integrity breach of the RO membranes, pathogens can’t pass. The last step is AO. This is the application of high inten sity UV rays through the water, with a chemical supplement (usually hydrogen peroxide) meant to form hydroxyl radicals. These are highly effective at oxidizing any remaining constitu ents, including any pathogens should they get through UF and RO, along with trace contaminants such as residual pharma ceutical products. UV irradiation also is assigned a pathogen removal credit meant to indicate effectiveness. Regulations are emerging worldwide for how much patho gen credit needs to be verified to use wastewater as a potable source. One of the leaders in this development is the state of California, as they have been widely affected by drought and multiple communities have had to look for non-traditional sources of water to make up their potable supply.

The City of Calgary engaged AE and Green Analytics to conduct a final valuation that demonstrates the value of the services provided by natural assets. The objective of the proj ect is to support the city in communicating the value of their natural assets that will be used to inform decision making on land-use planning, asset management, and operations. Green Analytics conducted the financial valuation compo nent of the project. AE’s team developed a unique data set to identify storage capacity in natural depression areas, which was compared to the cost of providing storage through engi neered stormwater infrastructure. It initially developed this data set to support Calgary’s stormwater team in quantifying the impacts of localized flooding, primarily focused on low points along the roadway network.Nature supports climate mitigation initiatives by storing carbon, as well as managing climate risks. Increased rain fall intensity, extreme temperatures and heat days, increasing runoff, and shifting eco-regions are all moderated through a healthy, resilient natural environment. The project provides a strong foundation for more robust management of Calgary’s natural assets and demonstrates that natural infrastructure is providing quantifiable financial value. Further analysis will make an even stronger case for advancing work on natural asset management and conservation efforts. Twyla Kowalczyk and Owen James are with Associated Engineering.

Connected approach helps City of Calgary improve natural asset management
Calgary’s plan for managing natural assets will improve the city’s resilience to the changing climate. By Twyla Kowalczyk and Owen James I n recent years, the City of Calgary has been focusing on pro cesses to improve the management of their natural assets.
Nature provides numerous social, economic and environ mental benefits. However, these benefits are usually underval ued in municipal financial planning and reporting. Determin ing the value of natural assets is an emerging field for munic ipalities.Withexpertise in asset management, municipal processes, and environmental management, Associated Engineering (AE) supports and assists organizations in developing and integrating natural asset management plans into their plan ning and processes.

biggest, Nice-Pak. Many, but not all, of these manufacturers belong to INDA, the Association of the Nonwoven Fab rics Industry, or its European counter part EDANA. Membership is voluntary, and even for members, adherence to association guidelines and recommen dations is voluntary. So, to address some of the growing concerns about “flushability” claims, INDA created their own guidance docu ment, but without any consultation with the North American wastewater sector. They even revised it a few times to get to their own Guidance Document GD-3. Our question was, who should decide what is “flushable”? The manufacturers, or the people that own and maintain sewer systems? So, together with our U.S. partners at the Water Environment Federation (WEF) and the National Association of Clean Water Agencies (NACWA), we reached out to INDA to support a revised Guidance Document or SeveralGD-4. times we thought we were cooperating and could reach a standard that was acceptable to our utility sec tor, but this standard would fail almost all of their products. So, there was no way INDA members would ever pass it. Instead, they would water down a stan dard until everyone’s products would pass again. Eventually we had to give up on this Meanwhile,effort. there was work done with wipes management and marketing teams in Washington on developing a Code of Practice. This effort was actu ally progressing really well and an agree ment was reached on a “flushable” logo that would go on products that passed the new GD-4. There was also a “Do Not Flush” logo that should appear on any product that could reasonably be used in a bathroom setting, such as body wipes, surface wipes, etc. We agreed on how big the logo should be and where it should be placed so it was clear to the purchaser (point of purchase) and also clear to each user (point of use). But sadly, we could not sign off on this Code of Prac tice as we couldn’t accept their weak ened GD-4 and definition of what was flushable. Again, this was all voluntary for the manufacturers and there was no enforcement.Ourfocus then shifted to developing an international standard through the ISO process. Wastewater profession als from around the world gathered in London, Ontario, for the very first meet ing to create an acceptable definition
What’s up with wipes? By Robert Haller and Barry Orr M unicipal wastewater utilities have always dealt with grease and feminine hygiene products, and tried their best to educate cus tomers to only flush the 3Ps – pee, poop and paper (toilet paper). We would get the odd clog, but we were doing “fairly” well, until the introduction of wipes. Initially, these baby wipes were intended for babies and when soiled, were wrapped up inside the diaper and placed in the garbage. But they were never clearly labeled as “Not Appropriate for Flushing”. Then came an onslaught of wipes for cleaning surfaces and for cleaning adults. They were called dis posable, all-natural, biodegradable, but they didn’t say “Do Not Flush”. And, if they did, it was in small print on the back and usually under the flap or fold. Then, some brilliant mind in a market ing department invented the word “flush able”. Did they immediately create a defi nition of “flushable”, or really think about what that meant, or if it was truly safe to flush? Did they consult with wastewater professionals or any utilities? No! Competition in the baby wipe sec tor exploded. Then quickly expanded to many more products. Soon, there was a special flushable wipe for everyone, plus ostomy products and even flushable toi letThisscrubbers.resulted in clogged sewer lines, damaged pumps, covered screens, and in many cases, the creation of “fatbergs”. This may seem humorous to the media, but we knew that it meant the shutdown of sewer systems, tremendous costs in staffing to clear lines, and to repair or replace equipment. We put our work ers at risk to climb into this stuff, we saw sewage back up into homes and busi nesses, and we saw raw sewage over flows into public spaces and waterways. There are many manufacturers around the world, but we mostly know the bigger companies like Kimberly-Clark, Proctor & Gamble, Albaad, Rockline, and the
of flushability and develop appropriate product tests. But, rightly so, the ISO process demands the involvement of all stake holders, including the manufacturers. We soon realized that our budget-strapped utilities and wastewater associations were up against a multi-billion-dollar indus try. Eventually, after tens of thousands of dollars were spent to meet in locations around the world, we had to abandon this process. A formal complaint was launched by the wipes manufacturers to ISO that the TC 224 Work Group 10 was out of scope. ISO agreed and our work was turned into a technical report (TR 24524). We had genuinely tried to work with the industry through INDA, then ISO, but now we had to go it alone. From the ashes of that failed ISO effort came the IWSFG – International Water Services Flushabil ity Group. The group included Barry Orr, Robert Haller and Tony VanRossum for Canada, WEF and NACWA for the U.S., plus representatives from wastewater associations in Australia, New Zealand, Japan, Spain and Turkey. The IWSFG soon developed a publicly available specification (PAS) and revised it twice. The PAS document addressed the concepts of “dispersibility” and developed the testing requirements for a product to be approved as “flushable”. The test includes toilet tests, pipe tests and slosh boxes. The PAS document also addresses logos and labelling and it has been adopted and endorsed by many waste water associations and municipal utilities. Meanwhile, on the legal front, there were a number of lawsuits launched in cities across the U.S. and one formal complaint submitted to the Canadian government. Here in Canada, CWWA was a co-signer with Friends of the Earth and a few other environmental organi zations, to make a formal complaint to the Competitions Bureau, a branch of Industry Canada.
The complaint named 12 products which we strongly believed had “falsely” or “inappropriately” been labeled as “flushable”. We even asked for a signifi cant fine of $1 million against each prod uct manufacturer. After a few months, we received confirmation that the complaint had been accepted for investigation. Two years passed before we received another letter, but this one said that they had decided not to investigate this complaint. While citing some concerns about cost and internal resources, their main argument was that, from what they determined, “there are a number of com peting guidelines”, and that “at this time, enforcement action of the Act does not appear to be the most effective means of addressing the issue of what can be safely disposed of in sewer systems.” We disagreed with this reply and we have since responded to this letter and asked the Minister of Innovation, Sci ence and Industry to review the decision. We pointed out that there are not a “number” of guidelines, there are only two. The IWSFG PAS that has been continued overleaf…

developed by certified wastewater professionals whose pur pose is to serve their community and protect the environment. The second one is INDA GD-4, which was developed by and for the manufacturers whose sole purpose is to maximize sales in order to maximize profits for shareholders. Again, who should decide what is suitable for disposal in the sewers owned and maintained by the community utility? Sadly, no one from the federal government reached out to CWWA or any of the complainants or to any municipality as part of their cursory review. We believe that enforcement action is the only way to address this issue and get the attention of the multi-bil lion-dollar wipe industry. At the very least, we were expect ing the federal government to investigate and say “we have a problem here” and perhaps show us a road map to get us to that enforceable standard similar to terms like “vegetarian” or “organic” or “Kosher” or “Halal”. Meanwhile, they have advanced with a similar complaint against Keurig, including significant fines, for claims that their coffee pod is “recyclable”. It is actually accepted in many recy cling programs but not in all programs. So why act on this and notAswipes?wesaid earlier, the only way to get the industry’s atten tion and move them toward a reasonable standard is through legal action. Over the last five years or so, there were a number of lawsuits initiated against wipes manufacturers and sellers by IWSFG testing requirements for a product to be approved as “flushable”, include toilet tests, pipe tests and slosh boxes. municipal utilities across the U.S. Some of these included Washington D.C., Washington State, California and one in Charleston, South Carolina. The City of Charleston sued several major wipes manufacturers and retailers to recoup damages to their sewer systems due to the inappropriate flushing of wipes. This case was getting seri ous! Suddenly, there was movement from the manufacturers. It started with Kimberly-Clark that negotiated a settlement with Charleston in which they agreed never to label anything as “flushable” again unless it passed the IWSFG specifications. Shortly after this, we were contacted by some other big manufacturers including Rockline and Nice-Pak (the inven tors of the first KFC wipe), as they expect to come to similar settlement agreements with Charleston. This is an amazing step forward for all of us after over 10 years of effort. The only problem is that IWSFG doesn’t “for mally” exist. It is just a group of wastewater professionals meeting on Zoom calls. We are trying to find a format to incorporate or other wise legitimize the IWSFG, but for now we are proceeding on a trust basis with the industry. No state has fully adopted the IWSFG standard into law, although there are legislation attempts. However, INDA keeps blocking a definition of “flushable” and focuses on “Do Not Flush” labelling. Now that we have some major industry support, we are going to try the ISO route again. The IWSFG is involved and, this time, the process is to be led by our partners in Australia. Here in Canada, we are initiating a standard through the Standards Council of Canada. This effort is being led by former CWWA executive director and Water Hall of Famer, Duncan Ellison. We have great hopes for an enforceable standard here in So,Canada.what role can Canadian utilities play? First, we are going to need everyone to adopt and endorse the new IWSFG stan dard and flushable logo. Then, we will ask everyone to rethink their public education campaigns. Continue with the message that toilets are not garbage cans, but adapt their 3P message to say flush only the 3Ps, unless a product has the IWSFG logo. We have been collecting fun and effective campaign materi als for the Canadian Water and Wastewater Association web site and our national wipes committee is looking at how we will word this and share campaign ideas. The committee also hopes to continue efforts to create an enforceable standard in Canada. However, all of this will cost money. Perhaps we can pool funds to create a more universal campaign that can be easily used in all communities, especially smaller ones. Developing and approving a “standard” costs between $100,000 to $200,000. The Federation of Canadian Municipalities has passed a resolu tion supporting our efforts on wipes and encouraging munici palities to contribute financially when asked as they recognize the return on investment of building such a standard.

Aerial view of the new water reservoir.
AE’s project team undertook a three-year program with six contracts to design and construct the water system expan sion. The system comprises 64 kilometres of 250 mm and 300 mm diameter water pipeline from Smoky Lake, Alberta to the community’s boundaries, and was fully funded by the province.Twonew booster stations along the system ensure flows can be maintained to meet the demands of the community and existing service points. A joint funding split between the prov ince and ISC supported all costs for a new off-reserve water storage reservoir, and ISC funded the on-reserve water distri bution system. Two contractors worked to build a hill-top, gravity-fed water reservoir, as well as a new pipeline into the Whitefish Lake community. AE encouraged the use of local labour for the project. At the peak of construction in the summer of 2020, local labour made up almost 50% of the waterline instal lation crew. In early October 2021, the existing Goodfish Lake Water Treatment Plant suffered a catastrophic failure and could no longer produce water. A public communication and water sys tem changeover strategy was quickly and efficiently organized to complete the transition to the new regional water supply.

By Ryan Krausher I n 2014, Whitefish Lake First Nation #128 approached Associated Engineering (AE) for advice on their drink ing water system.

It was determined that connecting to a nearby regional waterline would provide the most reliable and cost-effective water supply for the community. In collaboration with the Whitefish Lake First Nation, Highway 28/63 Regional Water Services Commission, Indigenous Services Canada (ISC), and the Province of Alberta, AE completed a feasibility study and developed a phased design and construction approach for a new water supply.

The EPA said the new levels were issued “in light of newly available sci ence and in accordance with its respon sibility to protect public health,” and that these new advisories indicate the level of drinking water contamination below which adverse health effects are not expected to occur. The EPA also notes that based on cur rent methods, the health advisory levels for PFOA and PFOS will be below the T he U.S. Environmental Protec tion Agency (EPA) has signifi cantly lowered its health thresh old levels for per- and polyfluoro alkyl substances (PFAS) in a move that could potentially impact thousands of water systems nationwide, but has also announced some $5 billion in grant funding to help communities prepare for and deal with these contaminants.
The decision involves two PFAS chemicals – perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), often noted as “forever chem icals”. PFAS are known for non-stick and stain-resistant capabilities, but are being phased out of production. Still, they include some 5,000 substances that can be used in products like food pack aging, firefighting foam, cosmetics, oil and water repellent chemicals. The manmade chemicals have been linked to liver damage, thyroid disease, decreased fertility, high cholesterol, obesity, hor mone suppression, and cancer.
EPA drastically tightens PFAS advisory levels
The EPA has identified a series of tech nologies that are known to reduce PFAS concentrations. They include activated carbon, anion exchange, and high-pres sure membranes. In Canada, PFAS threshold levels matched the 70 ppt standard previously used by the EPA. However, Health Can ada is currently preparing a state of PFAS report that will be completed within a year or two. Last year, the Ontario City of North Bay signed a deal with the Department of National Defence that provides nearly $20 million over six years to remediate PFAS from Jack Garland Airport. The airport had been used to train firefight ers and often used the chemicals in fire fighting foams. For more information, email: editor@esemag.com

Figure 2. N2O is typically the largest WWTP GHG emission based on current emission factors. Example is for a 5 MLD extended aeration plant including Scopes 1, 2 & 3 (chemicals only).
Over 500 municipalities and related organizations in Canada have declared a climate emergency. Key features of these declarations include committing to action, acting quickly, and establishing net-zero green house gas (GHG) emissions targets for circaGHG2050.emissions due to water and wastewater services are noted to be a rel atively small portion of national inven tories, with the waste sector typically around a few percent of total national emissions. However, from the perspec tive of a municipal corporation, GHG emissions due to water and wastewa ter services are much more significant. For example, the published emissions inventory from one Canadian regional municipality notes water/wastewater as contributing 26% of their GHG emis sions (Figure 1). Further, for water util ities where water and wastewater ser vices are their only business, those GHG emissions will comprise the entirety of their emissions inventory. Using current default emission fac tors from the Intergovernmental Panel on Climate Change (IPCC), most municipal wastewater treatment plants (WWTPs) will find that Scope 1 nitrous oxide (N2O) from liquid treatment will be the largest emission regardless of plant size, whether Scope 3 emissions are included or not. For example, Figure 2 illustrates an Ontario-based extended aeration plant without any natural gas usage. Electric ity is less than 10% of the total emission owing to the low carbon intensity of Ontario’s electricity grid. Although elec trical energy neutrality has been a large focus of our industry for the last decade, electricity tends to be a small proportion of the total GHG emission inventory when considering process emissions like methane and nitrous oxide. N2O FORMATION AND CAUSES N2O is a colourless, non-flammable gas with a slightly sweet scent and taste. It is ubiquitous in society as it has many uses, including most notably as “laugh ing gas”, the anesthetic used for dental work, as well as “nitrous” for racing per formance enhancement, and as an oxi dizer in rocket propellants. Importantly for the climate, the 100year global warming potential of N2O is 298 times that of carbon dioxide. N2O is also an ozone depleting chemical with an atmospheric lifetime of 121 years. Ravishankara et al (2009) argued that N2O has been the dominant ozone-de pleting substance of the 21st century. N2O is emitted by all secondary WWTPs owing to the multiple forma tion pathways as illustrated in Figure 3.

Based on review of the data used by IPCC for their 2019 refinement, it seems that the 1.6% emission factor is relatively too conservative. De Haas and Andrews (2022) found several errors in the data interpretation by IPCC and, after includ ing additional recent data from longterm monitoring studies, found the aver age factor to be 1.1%. Although this lower factor is reassuring, even at 1.1% the N2O process emissions remain the largest contributor to a WWTP GHG inventory.
Currently, it is extremely difficult to estimate a plant’s N2O emission a priori. Practically, N2O needs to be measured in situ, in order to determine whether it is a significant emission for any individ ual WWTP. Measuring also allows base lining and tracking emissions over time, allowing determination of whether miti gation approaches are effective at decreas ing emission levels. IPCC also recom mends plant-specific measurement as the best (Tier 3) estimating methodology. Interestingly, reviewing published emission factors with respect to moni toring duration and sampling frequency, Vasilaki et al (2022) found that reported emission factors increased with increas ing length of monitoring and frequency of Forsampling.duration, the average emission fac tor was 0.66% for studies of one week or less duration versus 1.74% for studies with greater than six months duration of mon itoring. For sampling frequency, inter mittent sampling studies had an average emission factor of 0.44% versus 1.2% for studies doing continuous monitoring. This makes sense since there are often seasonal variations to emissions and only longer duration and higher sam pling frequency will capture these vari ations. Therefore, measurement best practice for Canada is recommended as one year of continuous monitoring to capture all seasonally-high emissions. N2O can be measured several ways. Most commonly it has been measured using hoods on aeration zones, which capture off gas. N2O is measured by a gas phase analyzer (Duan et al. 2020). This system measures the actual gas phase emission from the process. Gas phase measurement has also been used ing nitrite to N2O (but not any further). The purpose is thought to be related to detoxification as well as maintaining thermodynamic conditions for contin ued ammonia turnover to keep produc ing energy. Pathway 3 is hydroxylamine oxidation; the AOB include enzymes to oxidize hydroxylamine to nitrous oxide (but not any further) under high DO. N2O formation is generally associ ated with environmental conditions that stress the microbiology and/or generally result in non-optimal environments for complete treatment.

MEASURING N2O AND ACTUAL EMISSIONS
N2O EMISSION FACTORS AROUND THE WORLD N2O emissions are typically reported as percent of influent total nitrogen emitted as nitrous oxide (as nitrogen). Reported emissions vary over five orders of magnitude, from nearly zero (0.001%) to over 10% of influent nitrogen. The historical global emission factor established by the IPCC 2006 reporting protocol was 3.2 g-N2O per capita per year based on a single study (Czepiel et al., 1995). Assuming 13 g-N discharged per capita per day, the 2006 factor works out to approximately 0.04% of influent nitrogen assumed emitted as N2O. This is very low and therefore has meant that historically N2O has not received much attention for mitigation. Research conducted since then mea suring N2O emissions at a variety of WWTPs found that the original study was under-representative of the typi cal average emission. The IPCC issued updated guidance in 2019 revising the default emission factor (and approach) Figure 3. Pathways of nitrous oxide formation.
to 1.6% of influent nitrogen. At this default factor, N2O is nearly two orders of magnitude higher when compared to the 2006 approach. As such, it will typ ically be the largest GHG emission in a WWTP’s inventory. Some countries have established their country-specific N2O emission fac tor. Australia’s calculation is based on 0.5% of total nitrogen removed by the WWTP, after subtraction of nitrogen in sludge. Denmark’s default is around 0.8%. Other countries, such as the U.K. and the Netherlands, are currently working on establishing their own fac tors. Canada does not currently have a country-specific emission factor. Due to site-specific variability, the IPCC factor is unlikely to be representa tive of any individual WWTP. However, it has brought to the forefront the impor tance of N2O process emissions and the need to measure and mitigate them.

Example of a typical distribution of costs related to the top four GHG emissions at a large wastewater treatment plant. in situations where the aeration off gas is collected either for odour control (Dael man et al. 2015), or because the plant is enclosed, e.g., in a mountain in Sweden (Baresel et al. 2016). This approach is probably the best in terms of being the most comprehensive and includes all N2O emissions from the process. Dissolved N2O can also be measured using a Clark-type probe. The mass emission rate is then calculated based on the measured aeration rate and assumption of the mass transfer correla tion. The dissolved measurement has been shown to be extremely well cor related with the gas phase measurement (Baresel et al. Measurement2016).of N2O emissions has indicated that some processes often implemented to reduce electricity con sumption may cause significantly higher N2O emission and consequently net additional overall GHG emission. Some examples include: • N2O emissions from deammonifi cation have been found to be in the 5% – 10% range (Ye et al. 2022). Some deam monification vendors are now using dis solved sensors to measure N2O and use the data in feedback machine learning systems to minimize emissions.
Much work is ongoing globally on the measurement and mitigation of N2O from wastewater treatment. An excellent current summary of the state of science is the recently published book “Quanti fication and Modelling of Fugitive Green house Gas Emissions from Urban Water Systems” edited by Liu Ye, Jose Porro, and Ingmar Nopens (Ye et al. 2022).

MITIGATING N2O
• Consider artificial intelligence and machine learning systems to control pro cesses for minimizing N2O emissions.
N2O is not directly related to energy consumption and there is no tax on N2O in Canada for wastewater treatment. Denmark will start taxing it circa 2025.
• Utilizing chemically enhanced pri mary treatment (CEPT) to increase car bon diversion to anaerobic digestion for net-zero energy targets. One utility found their emission factor jumped from 1.5% to 5.5% when implementing CEPT (Mik kel Andersen, Unisense, pers. comm.)
•include:Measure N2O to know your site-spe cific emission and whether it is significant.
Current understanding suggests it is unlikely that the wastewater industry can reach zero N2O emissions. Current best practice recommends firstly mini mizing N2O emission and then export ing renewable natural gas, thermal energy, and other resources that provide a net offset against the unavoidable N2O. For the Canadian wastewater indus try, the “inconvenient truth” of N2O emissions is that N2O is a potent GHG as all secondary WWTPs emit it. Also, N2O will be the largest GHG emission using the current IPCC 2019 emis sion factor. Your organization might be ignoring N2O, not aware that it is a sig nificant GHG, only inventorying ener gy-related emissions, or inventorying N2O based on IPCC 2006 values. In Canada, currently there is no direct cost of N2O, so there is no finan cial incentive to reduce it. At some point, however, you will need to spend money and measure it. It is also important to realize that energy-reduction process changes may make N2O emissions worse. Zero N2O emissions are unlikely, but we know a lot about them and they can be mitigated substantially.
• Manage ammonia loadings. For exam ple, avoid slug loads of high nitrogen con taining dewatering liquors back to the liquid train.
Current thatsuggestsunderstandingitisunlikelythewastewaterindustrycanreachzeroN2Oemissions.
• Provide adequate carbon for com plete denitrification.
Unfortunately, there is little finan cial incentive to reduce N2O emissions, as illustrated in Figure 4. Of the typical top four GHG emissions at an example WWTP, N2O has no direct cost attached to it. However, electricity typically rep resents the highest proportion of cost. But, this is often less than 10% of the GHG emission in Ontario as already noted. This asymmetry between cost and GHG contribution is why most facil ities are focused on electricity reduction instead of true GHG reductions.

T here are more than 10,000 closed and inactive landfills across the U.S. alone that could be given new lives as solar power hubs, accord ing to RMI, an independent non-profit focused on energy.
Landfills typically have good sun exposure, due to a lack of vegetation. Reinvesting in them as solar farms, often called brightfields, could help revital ize local host communities, suggests a report from RMI. “While some closed landfills have been repurposed as open space or golf courses, most do not have any planned future use,” states the RMI report, The Future of Landfills is Bright. “Thus, installing solar on landfills avoids land-use con flicts with other economic, agricultural, housing, or recreational activities.”
Another advantage listed in the RMI report for using solar at landfills is the extent of existing infrastructure already available, often including connections to electric distribution and access roads nec essary for construction and operations. Additionally, landfills can often be located in lower-income areas of a municipality, so the report’s authors note that “reuse of these sites not only pro vides a sustainable, non-hazardous reuse, but also an opportunity for community solar, education, and non-hazardous reinvestment.”TheU.S.Environmental Protection Agency determined in 2016 that closed and capped municipal solid waste land fills “often offer an ideal location for solar installations.” Through 2019, the EPA identified 205 completed solar projects on or adjacent to landfills that, collec tively, are capable of generating approxi mately 500 MW of electricity.
While solar farms are not booming on capped landfills, there has been a 10-fold increase in energy capacity com pared with recent years, and it includes the three largest projects in the U.S. to date. One solar landfill farm in Ohio, announced last September, will gener ate 50 MW of energy. Another project announced last year is being developed on 240 acres of landfill in Houston. But, there are some challenges with landfills compared to a standard parcel of undeveloped land, the report sug gests. Project designs must account for landfill cap characteristics, site grading, and land settlement as waste decays over time. For more information, email: editor@esemag.com
Closed landfills, which take up a tre mendous amount of land, could host an estimated 63 gigawatts (GW) of solar capacity in the near future. But to date, just 500 megawatts (MW) have been installed on landfills in the U.S.
A solar project is also located at Saska toon’s Landfill Gas Collection and Power Generation System as part of the city's

The practice is also catching on in Canada, where the Shepard Landfill in Calgary provides some 1,080 kW of power directly to the city’s composting facility. Officials say that the combined project will produce some 4,392 kW, enough electricity to power almost 750 average Calgary homes every year, while helping to avoid the generation of over 3,600 tonnes of greenhouse gas emis sions per year. And, last year, Yukon’s Dawson City announced it would be transforming the municipality’s former landfill into a solar farm capable of generating 280 MWh of energy annually, reducing the city’s dependency on backup diesel gen eration, and displacing 91.6 tonnes of annual GHG emissions.

This equates to $1.38$1.48 per month for the typical residen Department. “Wipes that claim to be flushable aren’t. Flushable wipes retain their shape and strength, and don’t break down in pipes.” Wet wipe clogs can cause “stop points” in city pipes, officials explained. That means sewage may have to be lifted to make its way to wastewater treatment plants. Wipes can also snag on pumps

Digital technology helps new employees by documenting the knowledge and experience of longtime workers.
Dealing with old technologies, unsup ported infrastructure, and monolithic architecture is an unfortunate reality for many cities and agencies. These out dated systems not only leave organiza tions vulnerable to cybersecurity threats, they also create a management night mare for IT teams. They require a lot of time and resources just to keep the lights on and are not appealing to the new gen eration of workers that are very much needed in the municipal water industry. Advances in digital technology have created an explosion in data in all aspects of our lives, and water is no exception. According to recent statis tics, almost 52% of workers in the water industry are over 45 years old, and 30% are due to retire in the next 10 years. An aging workforce makes succession plan ning urgent, and attracting and retain ing employees is crucial. Utilities are competing with other industries for the same talent. Convinc ing new graduates and young profes sionals, Generation Z and Millennials, that exciting opportunities exist within a utility company or monitoring agency, will require the industry to make funda mental changes.
G overnments, environmental agen cies, and utilities are in various stages of maturity in collecting all types of water data. Much of this data is still gathered in silos across dif ferent departments at the organization level and across state and local govern ment as well as industry organizations. Too often, data resides in on-prem ise hardware and interacts with legacy software that doesn’t have the analytical capabilities to demonstrate real insights. Without proper analysis, water profes sionals miss out on information that could be critical to completing essential tasks such as maintaining aging water infrastructure or managing stormwater flows. Organizations need to find a way to break down silos, consolidate data, and make sense of that data to achieve better, more sustainable water management.

The new workforce is equipped to modernize water data management
By Erik Larsen
The new generation of talent has expectations that challenge previously established norms of employee experi ence. By creatively addressing a common key challenge, digitization, utilities can position themselves to compete in the battle for talent. The workforce is also changing. Gone are the days of the 9-to-5 workday, where people sit at their desks in the same office and share information by the water cooler. The pandemic accel erated a shift that had already begun, proving to employers and employees alike that remote work, well, works. Organizations that had lagged behind in the adoption of digital tools and pro cesses were spurred into action, with one in three companies deciding to pursue digital transformation due to COVID19. As a result, utilities have been thrust into digital collaboration and commu nication applications and processes to support remote workers, and, there fore, many of the business silos are fall ing to the wayside in support of remote cross-functional collaboration. Millennials and Generation Z are well-adapted to help their teams through digital transformation. These cohorts are digital natives, and they expect to be challenged and to perform work that interests them. This aligns well with a sector looking to implement and encourage the use of new technologies. By combining the best of all generations, it is possible to move towards collabora tive and interdisciplinary ways of work ing and speed up the change that has already begun.

WHERE TO START Bluefield Research forecasts that the annual capital expenditures for dig ital water solutions will double from 2019 to 2030, setting the stage for more advanced monitoring and management of critical infrastructure. Getting started on a project of this magnitude can be daunting so it’s best to start with a clear vision and strategy and then organize the four key pillars of data, people, pro cess, and technology. Below are some questions to help you get started: Vision – What is the desired future state? Data – What data do I have? Where is it stored? How do I turn it into insights? Do I need to connect to other data sources (internal or external)? People – What skills are in-house now? What skills will we need in the future? Is leadership on board? Do I have an executive sponsor? Is the team structured the right way? How do I plan for change management? Process – What are my core processes today? What should they look like in the future? What can be automated? Technology – Do I have the right tools for the right jobs? Will my current tech stack scale with my vision? What modern technologies can we use? As organizations progress on their digital transformation journey, one of the main challenges they face is resis tance to change. Cultural change within a water utility requires C-level execu tives to have a clear vision, and internal advocates with a strong conviction to change the Incomingsystem.Millennials and Genera tion Z workers are technology natives and are great assets for digital transfor mation. Getting people on board with your mission will be the most critical success factor. Technology partners can help organizations guide their change management strategies to ensure the success of any new technology projects. While every water organization is unique, many of the challenges are sim ilar: legacy systems, data silos, lack of resources, etc. Experienced technology partners like Aquatic Informatics have seen it all before and can help you over come any issues that arise as you plot your journey.

By ES&E Staff Y ukon University has agreed to deliver the classroom and certifi cation portions of Indigenous Ser vices Canada’s (ISC) Circuit Rider Training Program (CRTP) for First Nations water and wastewater systems operators.Under the CRTP, experts rotate through a circuit of First Nations com munities, training the people responsi ble for operating, monitoring and main taining drinking water and wastewater systems. Now, ISC states that centraliz ing delivery of the CRTP and the Yukon Water and Wastewater Operator Pro gram (YWWOP) within Yukon Univer sity, will “enhance the delivery of both programs, benefiting water and wastewa ter operators and the communities they serve,” said a university announcement.

Yukon University, formerly Yukon College, received university status in the spring of 2020, becoming Canada's first university located north of the 60th parallel. It is now a hybrid institution that offers trades programming, aca demic upgrading, certificates, diplomas, degrees and applied research. Earlier this year, the university added a mobile water treatment lab to provide hands-on training experience to opera tors and Understudents.thenew delivery model, ISC states that there will be greater levels of participation by First Nations in both programs, as well as more opportuni ties to promote water and wastewater operator collaboration, recruitment and retention. ISC officials also said that a centralized delivery model will improve support for First Nations leadership and managers who oversee community water and wastewater systems management. “There has always been a fair amount of cross-over between the two pro grams,” Vernon said. “For example, the experts contracted through CRTP pro vide guidance on the frequency and course options delivered by YWWOP and also provide instruction for some of the courses. Bringing the two pro grams together at YukonU will allow for greater synergy. We believe this will lead to increased opportunities for col laboration between operators and com munities, for promotion of the water and wastewater operator career path, and retention of existing operators. It will also offer greater opportunity for applied research on northern commu nity water and wastewater systems.”
CRTP experts also give advice to chiefs and councils on how to develop safe water systems. In some regions, they also provide 24/7 emergency support to communities.YukonUniversity said it will continue to run YWWOP for other operators in the region. It has been delivering the program since 2009, helping current and prospec tive water operators gain and enhance the skills and certifications needed to work and succeed in the drinking water and water sanitation sectors. The program is funded by ISC in partnership with the Government of Yukon. ISC invests some $12 million per year in the CRTP.
“The Circuit Rider Training Program provides on-site training, troubleshoot ing and mentorship directly in First Nations communities. However, the program does not deliver the classroom instruction required for all operators in the region to gain and maintain the cer tifications necessary to operate commu nity water systems,” explained Michael Vernon, senior communications coordi nator for Yukon University, in an email to ES&E Magazine. Until 2023, the federal department is investing more than $411,000 for water and wastewater initiatives at the univer sity, including some $331,000 for delivery of the CRTP’s new delivery model. This builds on the approximately $168,000 provided over 2021-2022 for Yukon Uni versity to recruit a CRTP coordinator to deliver the program this fiscal year. “We look forward to the opportu nities for educational outreach, water and wastewater management and infra structure support, and the training and research that can flow from this consol idated delivery model,” announced Dr. Lesley Brown, Yukon University presi

“When there is only ruthenium, the water gets in the way,” Muhich said in a statement. “When there is only copper, there isn’t enough water to provide hydro gen atoms. But, on the single ruthenium sites water doesn’t compete as well, provid ing just enough hydrogen without taking up spots for nitrate to react,” he added. For more information, email: editor@esemag.com
Researchers see sustainable alternative in converting wastewater into ammonia
The research team used density func tional theory calculations to explain why ruthenium atoms make the chemical path that connects nitrate and ammonia easier to cross, according to Christopher Muhich, an assistant professor of chemi cal engineering at Arizona State.
These are not insignificant, amounting to 1.4% of the world’s annual emissions, the researchers noted. Some 175 mil lion tonnes of ammonia are produced at plants every year through intensive industrial processes. China, for instance, produces more ammonia than any other country, and produces the majority of its ammonia from coal.

The remaining nitrogen contents after these wastewater treatments can be brought down to “drinkable” levels as defined by the World Health Organiza tion, said the researchers. A prime benefit of the conversion pro cess is the reduction of carbon dioxide emissions from traditional industrial production of ammonia, one of the most highly-produced inorganic chemicals.

S ome 50% of the world’s food pro duction relies on ammonia fertil izer. A new study, led by Rice Uni versity researchers, has taken steps toward producing fertilizer in a more sustainable way through the electro chemical conversion of nitrate ions to ammonia in wastewater. The process converts wastewater nitrate levels of 2,000 parts per mil lion into ammonia, followed by an effi cient gas stripping process for ammonia product collection, explains chemical and biomolecular engineer, and study co-lead, Haotian Wang. Wang designed a catalyst of ruthe nium atoms in a copper mesh to extract ammonia from nitrate-rich industrial wastewater and polluted groundwater, the study states. The copper suppresses the hydrogen evolution reaction, the researchers found. “While we understood that convert ing nitrate wastes to ammonia may not be able to fully replace the existing ammonia industry in the short term, we believe this process could make sig nificant contributions to decentralized

By ES&E staff A new partnership between the Council of the Great Lakes Region (CGLR) and The Water Council (TWC) pro vides a framework to advance corporate sustainability performance and water stewardship across the region, the groups announced. The pair views corporate water stewardship as a growing necessity in the face of climate change and its increased risks of droughts, floods, deteriorating infrastructure, and poor water quality. In response, the groups will run a new regional effort called the Great Lakes Water Innovation and Steward ship Exchange, or Great Lakes WISE.
Fisher noted that it’s important for companies to realize that just 1% of the Great Lakes are renewed annually by precipita tion, runoff and groundwater, and water systems above and below ground are constantly at risk of pollution and depletion, with a rapidly changing climate worsening water stress.
Mark Fisher, president and CEO of the CGLR, says that his group will work to help TWC grow its WAVE: Water Steward ship Verified program. It’s an initiative that helps companies follow a strategic process to understand their water uses and impacts, assess associated risks across the enterprise and pri oritize the highest risks.
It is a business-led forum for deepening peer-to-peer conver sations, policy research, and advocacy about water resources protection, best practices and challenges requiring leadership and action by corporations and government in the region.

Canadians agree on range of environmental issues, U of T study finds
An analysis of Statistics Canada data by researchers in the University of Toronto Scarborough’s Department of Phys ical and Environmental Sciences has found that most Canadians aren’t too far apart when it comes to views on the environment, except when it comes to climate change.
“We found that political conservatism influenced some cli mate change-related behaviours, but overall, we don’t find a significant ‘conservative-versus-liberal’ divide about the broad er-spectrum of environmental issues,” said Arhonditsis. “It’s not like conservatives recycle a lot less, are more wasteful with water or don’t care about green spaces compared to liberals,” he added.

The study found few differences when it came to comparing urban to rural behaviors around the environment.
The study showed that the majority of Canadians revealed a “tendency for environmentally aligned practices concerning their recycling and hazardous waste disposal practices”, with a trend in British Columbia and the Prairies to recycle primarily for reducing waste in landfill sites or the demand for raw mate rials, and social responsibility.
A notable difference with younger people who took the sur vey was that they are more likely to be involved in environ mental activism. This includes dedicating time and resources to volunteer activities aimed at conservation, cleanup projects and protection or restoration of wildlife and habitats.
In terms of anomalies, the study found that a higher median age is slightly more likely to equate with making environmen tally-friendly product purchases, and greener waste manage mentThepractices.studyalso revealed that communities with an older median age are more likely to use fewer chemical fertilizers and pesticides, purchase more locally grown food, and own water meters and water-saving showerheads.
One interesting observation from the study may be the impact of politics in relation to the environment, researchers found. For instance, the study noted that conservative-leaning respondents often tend to be more reluctant to take actions aimed at climate change, such as purchasing electric vehicles or adopting renewable forms of energy.
For the study, researchers examined a set of 59 questions from StatCan’s Household and the Environment Survey. The subjects covered issues such as air quality, energy use, waste disposal, and household water.
“A real positive finding is that Canadians, regardless of their age, income, location, politics or income, are not deeply divided on many very important environmental issues,” said Professor George Arhonditsis, study co-author, in a statement. Arhon ditsis co-authored the study with PhD student Cindy Yang.

Using a phosphorus coagulant can improve wastewater UV disinfection performance
H ow much can a phosphorus coagulant influence the per formance of a wastewater plant’s UV disinfection sys tem? A lot more than you might think. After switching to ClariPhos™ rare earth coagulant to evaluate its ability to improve phosphorus removal, operators at an Ontario WWTP noticed that UV disinfection also expe rienced a big boost. It turns out that better settling in the clar ifier led to higher UV transmittance in the effluent, and a sig nificant improvement in UV disinfection. UV transmittance, or UVT, is a measurement of the UV energy that passes through a water column relative to the energy emitted by a UV lamp. Low UVT means that sus pended or dissolved contaminants are blocking or absorbing UV light and preventing the UV energy from reaching target pathogens. High UVT means the opposite. In this case, UV light can easily pass through the water column and effectively inactivate pathogens. Prior to switching to ClariPhos, the plant was using ferric chloride to precipitate phosphorus. With this chemical, the plant typically achieved UVT in clarified effluent of about 55 – 60%. With ClariPhos, the plant was able to consistently achieve UVT above 60%. This coagulant improves clarifier performance because it is made with the rare earth elements cerium and lantha num, which have a very high affinity for phosphorus. These elements form a tight ionic bond with phosphorus to create rhabdophane (Ce/LaPO4), a dense and insoluble precipitate. ClariPhos precipitate is also more stable and heavier than that produced by some other coagulants, so it settles up to two times faster. The results are improved clarifier performance and reduced risk of carryover of suspended solids. In most cases, plant operators can simply replace conven tional alum or ferric coagulants with ClariPhos. It doesn’t require special chemical feed equipment and will often work with existing feed pumps. For more information, visit: www.bishopwater.ca

Environmental Science & Engineering Magazine38 | August 2022 DISINFECTION
Higher cost, lower supply – For now, PAA is more expen sive than chlorine-based disinfectants, and the number of manufacturers and distributors is far fewer. However, as acceptance of the substance increases, these factors are likely to change.
THE PROS AND CONS OF PAA
In addition, PAA is beginning to make inroads in drink ing water treatment. Its main use is to treat influent to remove bacteria and oxidize other microorganic matter. Used in this manner, it is not a substitute for chlorine, but rather a way of mitigating total organic matter that can react with chlorine to form DBPs downstream.
APPLICATIONS FOR PAA
What you need to know about peracetic acid for water treatment disinfection
At present, the two most common applications of PAA are in healthcare and food sanitation, due to its ability to break down into predominantly neutral components (oxygen and water).PAA has been finding increased usage in industrial waste water treatment. Manufacturers that produce organic waste, such as food processors and breweries, are increasingly apply ing PAA as a pretreatment before further treating and dis charging effluent. A number of studies have also been conducted regarding the effectiveness of PAA in municipal wastewater treatment to reduce biofouling. So far, it is finding adoption among munici palities with high levels of industrial waste for which UV treat ment has been ineffective. It is also popular in areas that are struggling to meet maximums for chlorine-derived DBPs.
By Amparo Burke C hlorine and chlorine compounds, like sodium hypochlo rite, continue to be the go-to chemicals for disinfection in both pretreatment and post-treatment applications. But, chlorine has many drawbacks. For example, chlo rine reacts with organic matter to form disinfection byprod ucts (DBPs), many of which are known to have long-term carcinogenic properties. Chlorine also breaks down quickly, making long-term storage difficult. Chlorinated water that enters the environment can be harmful to plants, insects and animals alike. This has led to a growing interest in peracetic acid (PAA) as an alternative to chlorine for disinfection in some appli cations. PAA has a unique chemistry that is highly effective against bacteria and other contaminants. It does not form any known DBPs and has less environmental impact. Before substituting chlorine with PAA, it is critical to under stand the chemistry, its applications, and methods of handling and dosing.
PAA is an organic chemical made from combining acetic acid with hydrogen peroxide using a catalyst. It has a vine gar-like odour and is typically sold in a solution of acetic acid, peroxide and water. PAA was first used as a disinfectant in the early 1900s and was registered as a disinfectant with the U.S. EPA in 1985. Benefits of PAA include: Environmentally friendly – When it oxidizes, PAA breaks down into acetic acid, water and oxygen. This makes it safer to use on effluent that is discharged into source water or other bodies with high levels of organic content. PAA oxidizes almost instantly, so there is rarely any residual chemical after discharge. Regulation agnostic – For now, there are few regulations that affect the use of PAA, as it breaks down quickly and does not form any known DBPs. Long shelf life – PAA has an estimated shelf life of six months to two years. By comparison, sodium hypochlorite has a shelf life of about 90 days. Of course, PAA is not without its drawbacks. Some things to note about the substance include: Highly corrosive – PAA can cause severe damage to the skin, eyes and lungs. Those handling the chemical should do so in a well-ventilated room, wearing appropriate protective gear. It can also corrode metal and some polymers. Limited effectiveness on viruses – While PAA instantly kills bacteria and fungi, it has been proven less effective on protozoa and viruses, including Giardia and Cryptosporidium. (It will kill SARS-CoV-2 on hard surfaces.)
HOW TO ADMINISTER PAA TO A TREATMENT SYSTEM
Multi-diaphragm pumps overcome this problem, as they have two chambers. As one enters the suction position, the other enters the discharge position, and vice versa. This ensures a steady, smooth flow in and out of the pump, allow ing it to run at high speeds and avoid vapour locking.
A multi-diaphragm pump with a chemical-resistant mem brane is an ideal solution for metering PAA, which might be too off-gassing and caustic for other diaphragm or peristaltic pumps.However, not every multi-diaphragm pump can handle caustic chemicals like peracetic acid. It is important to check with the pump manufacturer to ensure a multi-diaphragm pump comes with a chemical-resistant membrane. Amparo Burke is with Blue-White Industries. For more information, visit: www.bluewhite.com Multi-diaphragm pumps like Blue-White Industries’ MD1 overcome the problem of vapour locking, as they have two chambers.
Dosing PAA into a water treatment system requires the right equipment. The caustic properties make it difficult to run through some kinds of pumps. For high-flow applications, a peristaltic pump could work, although it is important to ensure that the pump tube has good chemical resistance. Lowflow applications usually call for a diaphragm pump. However, PAA off-gases, which can cause vapour locking.

There are 21 proposed water projects in the new plan for the region, which proposes to spend $2 billion over the next three decades, and address a population that will require more water byLocated2045. at the Sooke Reservoir, a key component of the new plan would be the proposed Goldstream water filtration plant, a single direct filtration plant located upstream of the Gold stream disinfection facility, according to Capital Regional District (CRD) officials. With a tentative completion date of 2037, the filtration plant would protect the regional water supply from potential raw water quality fluctuations from cli mate change, forest fires, and the integration of water from the Leech and Goldstream water supply areas.
“The addition of filtration in combination with existing dis infection processes (ultraviolet disinfection followed by the addition of chlorine and ammonia) would provide a robust multi-barrier system able to better mitigate potential adverse raw water quality due to climate change impacts, reduce the vulnerability of the current treatment system, and protect pub lic health,” states an overview of the plan.
To make the filtration plant a reality, CRD officials are also recommending a $77-million east-west transmission main to connect the proposed filtration plant with the Juan de Fuca Water Distribution Service.

The impact of Ontario’s new blue box regulation
By George Jaikaran
Ancillary elements are parts integrated into the primary packaging and will be disposed of along with the primary pack aging, such as milk carton spouts. This regulation is also looking to expand and include some industrial, commercial, and institutional (IC&I) sources of product packaging, specifically from the government and institutional sectors, such as the packaging of products, like paper supplied to schools and hospitals.
Producers will now be responsible for the end-of-life han dling of their products and product packaging. The regulation also sets mandatory blue box collection system requirements and gives the affected producers choices for resource recovery services.Thecornerstone of the new regulation, of course, is what it defines as blue box materials. Under it, blue box materials are products and packaging made of materials that will be dis posed in the residential waste stream. It further breaks down blue box materials into three major types, which are paper products, packaging-like products, and product packaging. Perhaps the most significant category is product packaging, of which there are several sub-categories: Primary packaging is the main packaging used for prod ucts and includes all components, except those explicitly defined as transportation or convenience packaging. Transportation packaging is used to help transport prod ucts to retail locations. Specific examples include wraps, pal lets, and boxes.
U nder Ontario’s new blue box regulation 391/21, producers will soon be paying twice as much in blue box fees. The regulation, which outlines the rules for blue box mate rials, recently underwent updates that clearly demon strate Ontario’s commitment to integrating extended producer responsibility into its major waste diversion programs. It was released under the Resource Recovery and Circular Economy Act, 2016.

Ontario’s new blue box regulation makes producers fully responsible, including financially, for collecting their blue box materials and recycling them. Producers must also maintain the existing services across Ontario, and expand to additional locations, including remote Northern communities. This will happen during a transition period spanning July 1, 2023 to December 31, 2025. However, these are not the only ways in which the new reg ulation affects producers. Producers need to register with the Resource Productivity & Recovery Authority (RPRA), pay the

They can be for profit, or not for profit and act as rep resentation for the producer. Their ser vices include:
Producers need to meet the collec tion and resource recovery require ments attached to these materials as well. Reporting is also necessary for certified compostable products and their packag ing, though they have no requirements for resource recovery or collection. The blue box fees are based on these reports and the weight of blue box materials minus deductions noted in the regulation. The effects of the new regulation on producers makes it clear there is a signifi cant amount of work to achieve and main tain compliance. This is why producers have the option of turning to a producer responsibility organization (PRO) for assistance.

CONCLUSION Ontario’s Blue Box Regulation is a significant change in the way produc ers must handle the recyclable materials they produce as part of the product sold to their consumers. Producers are facing enhanced extended producer responsi bility throughout the life cycles of their products, which, under the regulation, means additional blue box fees, reporting categories, as well as reporting deadlines.

Grinder pumps like the two horsepower RAZOR (pictured) are designed for light commercial and residential solids handling applications. trending towards premium efficiency motors. To solve challenges in today’s waste stream, the pump and motor combination has to evolve into a premium efficiency solid handling solution with installation flexibility and easier repair and maintenance.
There are three main pump/motor technologies in waste water pumping: submersible, true dry pit, and dry pit sub mersible. Submersible and dry pit pumps have both had their respective corners of the market for quite some time, but the dry run submersible pumps are a newer style that merges the two technologies. These pumps have become more popular as environments change and a greater need grows for flood proof pumps and versatility in installations. Dry pit pumps are typically end suction style pumps with T he modern waste stream is continuously increasing in solids content. In recent years, wastewater professionals have witnessed unprecedented growth in flushable wipes being deposited and accumulating in the waste stream. Non-clog pumps that once were able to perform non-stop for years are clogging more often due to high solids content, requiring frequent maintenance. The evolving waste stream is increasing the need for robust solids handling pump technologies that will not clog fre quently and are able to withstand higher solids in the media. Additionally, with increasing focus on energy efficiency, cus tomers are looking for high efficiency pumps and motors.
Non-clog pumps are commonly found in applications involving sewage, effluent, wastewater processing and solids laden media. Non-clog pumps cover a large head range from three to 125 metres and have a flow range from 190 to 95,000 litres per minute, with some manufacturers offering hydrau lics that can reach even higher heads and greater flows. Chopper pumps are a great choice for highly demanding wastewater applications in the collection systems market. They feature superior solid size reduction, high reliability, ease of servicing, ability to upgrade and low life cycle cost. Chop per pumps are engineered to perform in some of the tough est applications, including: municipal wastewater, RAS/WAS sludge, agriculture, dairy & food processing, marine, commer cial wastewater and industrial wastewater.

SELECTING THE RIGHT TYPE OF SOLIDS HANDLING PUMPS
There are a variety of pump solutions available to effectively handle and reduce solids in the modern waste stream. Pump selection is dependent on application and required perfor mance parameters. Grinders, non-clog and chopper pumps are the best equipped pump solutions to handle the high sol ids content of todays’ waste stream, each applicable in different environments and High-horsepowerapplications.grinderpumps are a solution for solids handing applications that require high head and low flow. Both large and small grinders are most typically found in private residential or light industrial/commercial lift stations. Grinder pumps have a common head range between 10 and 100 metres, with flow ranges between 75 and 590 litres per minute.
SELECTING THE RIGHT TYPE OF INSTALLATION
While there have not been any higher efficiency regulatory requirements in the wastewater industry, many customers are

that do not clog with high efficiency motors that can be used in a variety of installations and applications. To address the non-clogging pump requirement, a few pump manufactur ers have developed a chopper pump solution, which is able to handle higher solids content media. A chopper pump relies on the blade design to reduce sol ids size. It can pass even the toughest of solids in waste stream like greasy hair balls, stringy ropes, pillows, glass, bot tles, nylon hose, wood dowels and other solids greater than 75mm in size. Some solutions in the market, like the Barnes SITHE chopper pump, have an open centre cutter design and hydrau lics to prevent solids build-up around the pump and in the volute and impel ler passageways, and pass the chopped solids without any clogging. The slicing blade and striker plate, made from heat treated 440C stainless steel, maintain their sharpness over time, thus retaining excellent solid size reduction capability. The slicing mechanism is designed to reduce solids to a size small enough to a NEMA AC induction motor, and they are meant to operate in a completely dry environment. If they are installed below ground, they are often accompanied by a small sump pump to collect and remove any water that does make its way into theTheseinstallation.motors cannot be submerged without damage. If the pump sta tion floods, the motors must be either repaired or replaced, which can be time consuming and costly. There is a type of motor called “immersible”, but these can only be submerged for a short period of time without damage, and typically can not operate while submerged. Submersible pumps, on the other hand, are meant to operate in a sub merged environment. They are typically rated up to 20 metres of submergence, and often feature an oil-filled or air-filled motor. The pumps utilize the surround ing fluid for cooling and thus have a min imum submergence requirement. With out the minimum submergence require ment, the motor may not cool properly and may be susceptible to damage. Dry run submersible pumps are simi lar to the submersible ones, with all inter nal components sealed from the external environment. The motors are typically air filled, but they can be oil filled in some circumstances. The motor can either be derated to run cooler or could include a cooling jacket, which circulates a cooling fluid around the air-filled motor housing. Due to the presence of the cooling jacket, the pump can be operated fully submerged, partly submerged or dry.
prevent clogging of the pump and downstream check valve, but large enough to be trapped at headwork screens at wastewater treatment plant. The striker plate and slicing blade retain sharp ness for seven to eight years, minimizing the need for replace ment. Many wastewater treatment plants have started adopting this solution and have seen significant reduction in pump clog ging, resulting in labour and maintenance cost savings.

For a waste stream with high solids content where nonclog pumps clog frequently, a chopper pump can be a bet ter solution due to the ability to reduce solids size and pass even the toughest of the solids like hairballs, ropes, pillows, glass bottles, etc. Combining the chopper pump wet end with a premium efficient IE3 motor can improve overall efficiency, reducing energy costs. Further, the chopper pump and pre mium efficient motor solution can be designed with different accessories to fit in any customer site, enabling easy service Ketan Pandit, Layla Wilhelm, and Mackenzie May are with Crane Pumps & Systems.

To address the need of a high efficiency motor, air-filled motors are gaining in popularity. Typically, air-filled motors have higher efficiency than oil-filled counterparts. The typi cal oil-filled motor is relatively low on efficiency, falling in the “IE0” level. “IE0” is not a formal efficiency rating, but simply means that oil-filled motors will typically be less efficient than even the least efficient air-filled motor.

While some pump manufacturers have been using the airfilled motor technology on non-clog pumps for a long time, very few have adopted this solution for a chopper pump. The Barnes Sithe envie3 solution is one such technology that pro vides application versatility and premium efficiency perfor mance for a chopper pump. An air-filled motor often includes a cooling jacket that cir culates a cooling fluid like clean water, process fluid, or a gly col-water mix around the motor housing. As a result of these merged or partially submerged. Because of the submersible capability in all installations, this pump is flood-proof. This can be advantageous in flood prone regions and in instances of accidental flooding (valve failure, force main break, etc.). The pump will not be damaged and will continue to operate, which may help mitigate the flooding, minimizing both pump down time and repair costs. Customers require pumps that can be installed in a vari ety of applications. Manufacturers have designed installation accessories that meet the needs of every application, whether in a wastewater treatment plant, or in the collections system. These can include the following: BAF: Breakaway fittings, also known as guide rail systems or base elbow systems, consist of a base elbow and slide rail adapter plus brackets and hardware, and provide for easy installation and removal of pumps in permanent wet well

$9.9 BILLION TO BE SPENT ON MAJOR IONA ISLAND WWTP UPGRADES IN BC BC’s Iona Island WWTP upgrade projects mark the largest capital program ever undertaken by Metro Vancouver. Credit: Stantec/Metro Vancouver Stantec is set to lead as program man agement consultant for British Colum bia’s massive $9.9 billion Iona Island Wastewater Treatment Plant (WWTP) projects in Richmond. The existing plant was built in 1963 and has been expanded six times to accommodate population growth and treatment upgrades. Now, a new facility will be built to replace the existing primary level treatment plant and meet all provincial and federal regu lations for wastewater treatment, Metro Vancouver officials say. These projects mark the largest capi tal program ever undertaken by Metro Vancouver. The new Richmond plant will improve the level of treatment from primary to tertiary to protect water quality and the marine environment and help to withstand earthquakes and rising sea levels. The plant will also recover sustainable thermal energy and resources from the wastewater, all while minimizing its odour. Also on tap are a range of ecological restoration projects that will better inte grate the plant with Iona Beach Regional Park, home to a rare community of sand dune plants in the midst of the Pacific Flyway and a popular site for thousands of migrating birds. Over the next four years, experts will perform geotechnical investigations and each of the treated sludge lagoons will be cleaned out to prepare for the new plant’s continued overleaf…
DRY JUNE LEADS TO WATER RESTRICTIONS IN SOUTHERN ONTARIO AND BEYOND As dry weather persists, water restric tions are becoming more commonplace across Canada, with water users in south ern Ontario’s Grand River watershed being the latest to be asked for a cut in consumption. The Grand River Conser vation Authority (GRCA) announced a new Level 2 advisory on July 2, which urged water users to reduce consumption by 20%. The cut is voluntary and applies primarily to municipalities, farmers, golf course operators, water bottlers, and aggregate companies. It is considered a Level 2 advisory under the Ontario Low Water Response Program. Between mid-June and mid-July, the GRCA watershed, which is about the same size as Prince Edward Island and has a population of about 1 million, received approximately 25% of the normal amount of precipitation for that period. To help Ontario’s largest watershed during the dry spell since April, the GRCA is using large upstream reser voirs to bolster river flows and maintain low flow targets on the Grand and Speed rivers. Discharges have been increased to maintain flows downstream, which, combined with evaporation due to per sistent hot, dry weather will add further pressure to all GRCA reservoirs as water levelsAugmentationdrop. from GRCA reservoirs accounted for approximately 80% of the flow in the Grand River through Kitch ener, 45% of the flow through Brantford and about 55% of the Speed River flow through Guelph. In Quebec, talk is growing around limiting new developments in droughtprone areas. It was last summer’s extreme heat and extraordinarily high water usage that was one of the primary factors in Metro Vancouver developing its new watering restrictions. Alberta’s Lake Diefenbaker has experienced extremely low water lev els this summer.

De Nora S.p.A. has been named best in the water technology & infrastruc ture category in the 2022 Water Europe Innovation Awards, for its sludge ozo nation application in advanced sewage treatment. The technology, suitable for municipal or industrial use, improves process efficiencies without the use of harmful chemicals, protecting the environment from micropollutants in accord with the European Union’s Zero Pollution Action Plan. The sludge ozonolysis is a simple plug-in process, where injectors dose ozone into a side stream of the returned activated sludge (RAS). Since no ozone buildup occurs, it does not leave a resid ual, allowing unreacted ozone to revert back to oxygen and be utilized by micro organisms in the aerobic reactor.

De Nora is represented in Ontario by Pro Aqua and SCG Process.
Current installations in Italy have shown success, minimizing excess sludge volumes, improving sludge settlement characteristics and effluent quality, and alleviating bulking problems. Dewater ability and micropollutant concentration levels are also improved – two character istics that will be key as treatment provid ers explore new technologies in response to directives regarding agricultural sludge valorization and landfilling. The application can also be used for sludge destined for biodigestion as the process increases the amount of biogas produced.
The larger SHARC system, installed in places such as Vancouver’s False Creek neighbourhood, which hosted the Olympic Village for the 2010 Winter Games, recovers enough heat to warm some 22 million square feet of apart ment complexes.
While the manufacturing and import prohibition on the single-used plastics begins in December 2022, the items will still appear on store shelves for sale until December of 2023. A ban on the export of plastics in the six categories will occur by the end of 2025, making Canada the first among peer jurisdictions to do so internationally, federal officials stated. Over the next decade, Environment and Climate Change officials estimate that the new single-use plastics ban will result in the elimination of more than 1.3 million tonnes of hard-to-recy cle plastic waste and more than 22,000 tonnes of plastic pollution. This is equivalent to more than a million gar bage bags full of litter. Two guidance documents have also been published. One is designed to help businesses adjust to the new regulations, and the other is to help anybody in Can ada choose more sustainable alterna tives to single-use plastics.

By ES&E Staff
N ow that the federal government has finalized regulations for a single-use plastics ban, it won’t be long before Canadians no lon ger have access to items such as plas tic cutlery and checkout bags in retail environments.Thefirstpart of the ban covers the manufacture and import of six sin gle-use plastics that many experts have found harmful to the environment and biodiversity, as well as comprising most of the plastic litter found on Canada’s shorelines.Rounding out the list of banned items under the new regulations are some forms of takeout food packaging, bev erage carrier rings, stir sticks, and most plastic straws. In the category of plas tic checkout bags alone, Canadians use some 15 billion every year. Overall, the country is able to recycle just 9% of its plastic waste. “By the end of the year, you won’t be able to manufacture or import these harmful plastics,” announced the Min ister of Environment and Climate Change, Steven Guilbeault, in a state ment. “After that, businesses will begin offering the sustainable solutions Cana dians want, whether that’s paper straws or reusable bags. With these new reg ulations, we’re taking a historic step forward in reducing plastic pollution, and keeping our communities and the places we love clean.”
Takeout or foodservice ware under the ban will cover items that use expanded polystyrene foam, extruded polystyrene foam, polyvinyl chloride, carbon black, and oxodegradable plastic. Exceptions to the ban on straws allow single-use plastic flexible straws to remain available for people in Canada who require them for medical or acces sibility reasons. This includes for use at home, in social settings, or in healthcare settings, such as hospitals and long term care facilities. All other types of sin gle-use plastic straws will be prohibited, officials announced. In 2019, companies such as Starbucks and Tim Hortons introduced “straw less” lids for cold drinks, allowing cus tomers to consume cold drinks without a straw. Other restaurants, like A&W, made the switch from plastic straws to paper straws in 2019. Red Lobster is sourcing and testing a variety of plastic straw replacements, one of them being redInlicorice.2021,fast-food chain McDonalds eliminated plastic stir sticks, straws and cutlery at more than 1,400 fran chises across Canada. These items were replaced by wooden alternatives. By eliminating these items, it is estimated that 840 tonnes of plastic are being diverted annually from landfills.
