Don't allow gravity to hold you hostage. ZENON'sZenoGem" immersed membrane bioreactor eliminates the need

for gravit}' settling of solids...putting the operator back in control.

ZenoGem" replaces conventional filtration and integrates clarification, aeration and sludge digestion into a single step process. Membranes are immersed directly in the mixed liquor and are driven by a slight suction. Filtered effluent is drawn through the membrane,wliile solids are retained in the process tank...allowing operators to have precise control

of SRT and to focus on optimizing biological treatment without the worry of settling problems. ZENON's ZenoGem® consistently produces a high quality effluent that exceeds the most stringent effluent discharge criteria,and is ideal for direct reuse or reverse osmosis feed.

For over 20 years, ZENON has been applying ZenoGem* membrane teclinolog)' to municipal and industrial wastewater treatment applications...proving that membranes can effectively replace clarifiers to save land space, increase effluent quality and reduce capital and operating costs.

British warship sunk in WWII stiii leaks oil Fresh way of separating oil from water

The problem of mopping up

bunker oil leaking from a sunken British warship has led to a compromise solution between the British Royal Navy (RN) who wish the wreck to remain an undis

turbed war grave, and environmentalists worried about the possible effects on local wildlife.

For 60 years the remains of the once mighty HMS Royal Oak have lain un touched, a grave for the 883 men who died when the battleship was sunk in the waters of Scapa Flow near the island of Orkney, off the coast of Scotland. Ever since the night in October 1939, when torpedoes from a German U-Boat ripped into her sides as she was moored, fuel

oil has steadily trickled out across the surface of the water. In recent years, the problem has risen as the thousands of tonnes of oil still in the corroding hull threaten a potential environmental dis

wreck poses a menace to Scapa Flow's large seal population and several species of rare birds. While respecting the crew's memory, conservationists want the oil removed as quickly and safely as possi ble. With this dilemma uppermost in their minds, the specialist and experienced engineers from the RN's Environmental Unit at Bath, western England, are con ducting a unique operation that they hope will remove the oil without needing to cut open the war grave. Divers will attach a steel umbrella

costing ÂŁ20,000 to the upturned hull to trap the oil before bringing it to the sur face where it will be removed each month. It is estimated that the wreck

will be empty by 2014. This novel so lution came about when Roger Tollervy, the project's director, realized that it was

divers gathering samples of the leaking oil ready for laboratory analysis. To do this, they rigged a temporary tent over the leak and funnelled the oil droplets into a container. Mr. Tollervy realized that if a structure could be put in place above the hull, the oil would float into

it. He asked his engineers to develop a permanent version using natural force rather than pumps, to collect oil that is circulating within the hull. He spent two years on the plan after retrieving the ship's plans from the National Maritime Museum in London, to create a three-

dimensional computer model. This al lowed the team to assess the structure

without entering the hull. Divers later established that oil was escaping through holes created by shrunken rivets. "The hull is surprisingly strong and is more sound than we expected," he said. "Our extensive structural surveys now judge the hull life to be at least 50 years. Although the superstructure is badly corroded, no oil is stored there.

Conservationists, anxious to protect Scapa Flow's seals and rare birds, would prefer a quicker solution. "It's a timebomb," said Eric Meek, an officer with

the Royal Society for the Protection of Birds (RSPB). "The ship is lying less than half a mile offshore and at this time

of year, Scapa Flow is an area of major importance for Arctic wintering birds." Sharing this concern is Bob Moore, director of Orkney Islands Council Har bours, who said: "It's a compromise but hopefully a speedier solution can be ar rived at in time." The RN Project team are mindful of these concerns and so,

once the canopy has been proven to be satisfactory, it will then considerably accelerate the flow using taps fixed to the rivets. Later, it will also investigate other ways of safely increasing the re covery rate.

In the remote event of any of this oil coming ashore in sufficient quantities to cause shoreline pollution, the RN have back-up and expertise at a huge oil ter minal located on the island.

Back from the future -a remarkable past

Millennium fever is cresting as ES&E com

pletes its 12th year of publishing, an appro priate opportunity to revisit the past and ex amine the quite remarkable progress in water treatment and public health. The literature shows that engi neers and chemists responded to life-threatening epidemics with remarkable prescience,research and intelligence. Sur prisingly, their efforts - and positive results- predate con temporary activism by more than a century. For example,in response to a 1854 cholera epidemic in Hamilton, Ontario, which killed 552 of the city's 14,000 inhabitants, the city commis sioned a waterworks and

pumping station. The remark able Thomas Keefer began building his steam-driven water pump which was com

Nor did he lack courage. After he traced a large number of deaths to the Broad Street hand-operated water pump in London's Soho district, he had

the pump handle removed, thus preventing water from this well being used. To cut off an area's water supply was a bold step which preceded Greenpeace by more than 120 years. His activism was bal anced by altruism when he published On the Mode of Communication of Cholera (1855). This painstaking work included a map of Soho which indicated the cholera

Millennium Reflections

Though Dr. Snow's work on germ theory was published in 1855, it was not until the 1870s that Robert Koch pub lished his findings after visiting Calcutta and Alexandria. He recovered the comma-shaped bacteria of vibrio cholerae from the intestines of people who had died of cholera, then learned how to cultivate them outside the body on beef-broth jelly. In 1884 he received a hero's welcome in Berlin, a medal and

100,000 marks from the Reichstag. In contrast to the recognition of Koch and Pasteur, Dr. Snow was never elected to the Royal Society and was virtu ally forgotten when he died of a stroke at the age of 44. His legacy gave long life to hundreds of thousands, perhaps mil lions. Most will never know that they, their parents, grand parents, great grandparents and beyond, might never have been bom but for a lone doctor's tenacity and foresight - a milestone in public health and pure drinking water. Another milestone in public health was the creation of theAmericanWater Works Association in 1881,tobejoined later by what is now the Water Environment Federation. These world-renowned bodies have done much to advance

the state-of-the-art in public health, with Canada having a strong presence reflected in several AWWA and WEE asso ciations and sections throughout Canada. Worthy of note as we enter the new millennium - only one person has ever been president of both the AWWA and WEE, Dr. Albert

As officer commanding No. 5 Mobile Laboratory in France, he had full supervision of all water purification for the First Canadian Army and latterly, the second British Army in the field.

other notable scientists as he embarked on his brilliant career

as both an academic and public servant. As the first General Manager and Chief Engineer of the Ontario Water Resources Commission in 1956, he presided over unprecedented construction of water and wastewater treatment plants throughout Ontario. 1 was privileged to discuss some of the OWRC data at a World Health Organi zation conference in Rome. Many delegates said this scale of treatment plant construction in Ontario was unmatched anywhere in the world. Regrettably, like Dr. Snow and Dr.

Nasmith, most people have never heard of Dr. Berry, nei ther have some senior Ministry of Environment people. This is astounding really as the Ministry stemmed directly from the OWRC.

These three men, a doctor, a chemist and an engineer, had a tremendous impact on the environment and public health yet they languish in obscurity. While activism is usually associated with protest move ments, many courageous initiatives were undertaken by these environmental pioneers. Working alone. Dr. Snow showed great tenacity and generosity of spirit as he pursued his re search and financed his own findings. Dr. Berry, scientist, engineer and civil servant,frequently took on politicians who were reluctant to upgrade water treatment facilities because they wished to avoid the costs. But, Dr. Berry, unlike Dr. Snow,had the power and resources of a rich province behind him, which, it must be said, he used wisely and effectively. Dr. Philip Jones, P.Eng., a key figure in the creation of the University of Toronto's Institute for Environmental Stud ies, collaborated with me on an article on eutrophication in 1968, in which he called for a reduction in phosphorus in laundry detergents.

The original article was also pub lished in Crisis^, an environmental anthology by MacMillan of Canada in 1971.

In remote areas, the use of this wind-powered system for site remediation promises to reduce costs, eliminate some of the environmental risks associated with other systems and in some cases, make remediation possible where it oth erwise might not have been. The windmills, called Windsparge, are already creating great interest among some major companies, notes Wayne McPhee, manager of remediation engineering and technol ogy for Conor Pacific. "Currently, diesel generators are used for remote-site remediation. Transportation of diesel fuel is costly and labour-intensive since it has to be regularly moni tored and tanks refuelled. In some cases, diesel tanks have

leaked and re-contaminated the area that is being cleaned up." The Windsparge, is a patent-pending process that uses soil bacteria and wind power to clean up contamination. The windmill powers an air pump that generates air flow and pressures to create effective flow of oxygen through the soil and groundwater which then encourages growth of microbes that degrade the contaminants. The air flow is kept at a particular level by accumulating in a pulse tank until sufficient pressure and volume develops. The Windsparge is claimed to effectively clean up bio degradable contaminants including gasoline, diesel,fuel oil and jet fuel. The windmills are low-maintenance and easily transportable, making them ideal for remote applications including former gas station sites, areas around pipelines and wellheads, former military bases where diesel and jet fuel have been used, DEW Line sites and anywhere where there have been spills or leaking tanks.

Provincial and federal legislation, regulations and moni toring will continue to protect the health and safety of Albertans and other Canadians. Legislation also permits BOVAR,which operates the Swan Hills facility, to directly import waste for treatment so the facility can operate to capacity. "The risk is in other countries dumping their hazardous waste without treating it. For example, even though Alberta's inventory ofPCBs is virtually eliminated, airborne

Alberta and federal laws strictly regulate what kind of waste can be accepted. For example, radioactive, explo sive or biological materials cannot enter the Province. Also,

Alberta and federal dangerous goods requirements apply to hazardous waste shipments. These shipments must follow designated routes, undergo regular checks and require spe cial containers or trucks. Drivers must have special train ing and a knowledge of emergency response procedures. In the last 12 years, about 10,000 shipments of hazard ous waste have crossed the Province to the Swan Hills fa

Alternatives favoured are landfill or incineration. But the former attracts an

As most un treated sewage sludge consists of around 90 percent water, in order to keep down the cost of treatment and subsequent disposal, it is imperative that the water nÂŁiS

Although traditional thickening proc esses - sometimes including the addi tion of chemicals and/or anaerobic di

Could global wanning even be beneficial? A controversial challenge to conventional thought

While US government officials have declared

repeatedly that global climate change science is "settled" and "compelling", a report released by the Center for the Study of American Business at Washington University, finds that increased global warming is likely to be minor and could even be beneficial. In What Do We Know About Human

Influence on Climate Change?, atmos pheric physicist S. Fred Singer reviews the state of climate change research and makes the following findings: 1) Any warming from the growth of greenhouse gases is likely to be minor, and, thus, difficult to detect above the natural fluctuations of the climate.

2)The impacts of global warming, and

of higher CO^ levels, are likely to be beneficial for human activities - espe cially agriculture. 3)The ultimate goal of the 1997 Kyoto Protocol on global climate change is still undefined; it could be a higher or lower level of greenhouse gas emissions. 4)The Kyoto Protocol, while economi cally harmful, would be ineffective in reducing the calculated temperature in

mate models for the year 2100. In the last 3,000 years, temperatures in the North Atlantic have changed by as much as 3Â°C within a few decades. During the most recent Ice Age, the variability was even greater. "Is the climate more stable during warmer periods? We can not be sure, but the evidence points in this direction," Singer says. The CSAB study reports that longerterm climate changes seem to be linked to continental drift and other tectonic

events. Shorter variations, on the time

scale of decades, appear to be caused by atmosphere-ocean interactions and changes in ocean circulation. Alterna tively, they could be due to external causes, such as the slight variations in the general solar irradiance (the socalled solar "constant") or in the highly variable solar activity. But for reasons as yet unexplained, the rate of increase of greenhouse gases in the atmosphere has slowed considerably in the last dec ade or so. "Perhaps the strongest argu ment against an appreciable human con

creased frequency and severity of stoims and a rapid rise in sea levels. But Dr. Singer notes: "The empirical evidence displayed in the IPCC report shows a decline in hurricanes over the last 50

years in both frequency and intensity." In addition, sea-level rise is found to

slow during periods of temperature in creases,suggesting that a future modest warming should slow down, not accel erate, the ongoing rise of sea levels. The CSAB study concludes that the 1997 Kyoto Protocol (calling for an av erage cut in greenhouse gas emissions of 5.2 percent from 1990 levels by in dustrialized nations by the year 2010) is not sufficient to reduce significantly the growth of greenhouse gases in the atmosphere; therefore, its effect on tem perature would be imperceptible. Fur ther, a warming, from whatever cause, is more likely to produce economic ben efits than economic losses.

The most widely quoted attempt to address climate changes of the past and to speculate about the future, is the se ries of reports produced by the United Nations Intergovernmental Panel on Climate Change (IPCC).

Water Treatment

Treatment plant energy cost efficiency About 85-95% of energy is used by high and low lift pumps

Energy conservation and energy cost-saving pro

grams for a water treatment facility typically cover high lift and low lift pumping, water treatment, heating, air conditioning, ventilation and lighting. The development and implementation of such a program could require substantial resources in time, people-power and finances, so identifying the most essential elements and priorities is very important. At water treatment plants, the greater part of energy con sumption (approximately 8595 percent) is by the high lift and low lift pumps. Therefore, these pumps offer the best po tential for energy cost savings.

to assess the potential for using "off-peak" utility rates, and calculate the potential energy cost savings. In most cases, this exercise can be completed in a few hours and does not require energy management experience. It is likely that sig nificant energy cost savings can be achieved only by chang ing operational practices that usually will not require any hardware modifications.

Outline of Approach

1. Collect and analyze Hydro bills. Tabulate the total, "offpeak" and "on-peak" energy consumption. 2. Analyze the treatment plant limiting factors and deter mine the maximum hourly water treatment capacity. 3. Analyze water distribution system limiting factors. Reveal the bottleneck(s) in the system.

By Valera Saknenko and Hershel Guttman, R.V. Anderson Associates Limited

It is obvious that operating the most energy consuming

equipment during the "off-peak" periods would substantially reduce the energy cost.

Step 2 - Analyze Treatment Plant Limiting Factors

Firstly, maximum hourly water treatment plant capacity should be determined. The capacity of all essential compo nents of the water treatment plant - raw water intake, low lift pumps, water treatment facilities, high lift pumps should be evaluated to identify bottleneck(s) in the system which would limit the capacity to treat and convey water to consumers during "off-peak" periods, and that capacity should be taken into account in further calculations.

Do not be misled by the necessity for backwashing. Energy consumption by backwashing is insignificant com pared to low lift and high lift pumping energy consump tion. The backwash practice should be reviewed,ifrequired,

from the point of view of minimizing its interference with water production during the "off-peak" periods. This will help maximize water production and water reservoir filling during "off-peak" periods. Continued on page 26

Water Treatment

Step 3 - Analyze Water Distribution System Analysis of the water distribution system should reveal any bottlenecks in the distribution system. The maximum capacity of the main elements of the water distribution system, such as maximum capacities of pumping station, water main(s) and reservoirs, should be estimated. Reservoirs

The total available equalization storage capacity of all in-line reservoirs should be determined. The available

capacity is equal to the total capacity of the water treatment plant reservoirs, in-line reservoirs and elevated tanks ex cluding fire and emergency storage, which should be kept

Step 5 - Estimate Energy Cost Savings After collecting all necessary data, a few more simple calculations are required to estimate possible energy cost savings associated with optimizing operational practices. Example of the Energy Cost Saving Estimate Step 1: Collect and analyze Hydro bills. The summary of all data required for estimating energy cost savings is presented below: Total energy consumption in 1997 Off-peak energy consumption

20,000,000 kW

11,000,000 kW

(55% of total) On-peak energy consumption

available at all times.

(45% of total)

Most utilities have established minimum and maximum

water levels in water reservoirs. In some cases, those levels

may be very conservative and a significant volume in the tanks(up to 25-30 percent) is not being used. This will also likely be true for relatively new reservoirs built to meet fu ture storage needs. Use of this excess storage at night-time can result in significant energy cost savings.

Step 4 - Estimate "Off-Peak" Periods Water Consumption Another key parameter in estimating energy cost sav ings is "off-peak" periods water consumption. If the data is not available, it can be estimated from the average daily water flow by applying the hourly water consumption rate factor, provided by guidelines, such as those published by the Ontario Ministry of the Environment.

To keep calculation simple, an average "off-peak" hours energy charge of 3.3 cents per kWh and "on-peak" hours energy charge of 6 cents per kWh were used. The total annual energy cost can be calculated as: 1 l,000,000kW * $0,033 -i- 9,000,000kW * $0.06 = $903,000 Step 2: Analyze the treatment plant limitingfactors and de termine the maximum hourly water treatment capacity. Analysis of all major components of the treatment plant, revealed that the bottleneck in the system is the capacity of the filters, which is then used in further calculations as the

Water Treatment

Step 3: Analyze water clistrihiition system limiting factors. Identify the bott!eneck{s) of the system.

For the purpose of this estimate, it was assumed that the total reservoirs volume is 110,000 m\ and the total required fire and emergency storage is 30,000 m\ Therefore, the total equalization and energy balancing storage available is 80,000 m\ However, to provide some comfort for opera tors in maintaining the minimum and maximum water lev els in reservoirs, an additional five percent of the total water reservoirs volume was reserved, or 5,500 m'. Thus the total equalization and energy balancing storage avail

able for the water distribution system is 74,500 m\ Step 4: Estimate water consumption by the system during "off-peak" periods. Assuming the data on "off-peak" periods water consump tion is not available, an estimate was prepared by applying peak rate factor, provided by the MOE Guidelines, to the av erage daily water consumption {MOE Guidelinesfor the De sign of Water Distribution System, July 1985, Appendix L). Average Daily Water Consumption Off-Peak (23:00 to 7:00) Water Consumption

Total number of hours required for producing and con

veying the weekly water demand into the reservoirs: 945,000 nf / 12 ,500 m'/hr = 75.6 hrs

b)Determine the number of weekday hours required to sup ply average weekday water demand: (75.6 hr / 7 days) * 5 days = 54 hrs

The maximum number of "off-peak" hours (from 11:00 p.m. to 7:00 a.m.) available for the facility during the five weekdays is 40 hrs: 8 hours * 5 days = 40 hrs

This means that the "off-peak" hours during the five weekdays are able to supply only 74 percent of the total weekday water demand: (40 hrs/54 hrs) * 100 = 74%

This number should then be compared with the avail ability of storage capacity calculated below. The lesser of these two numbers will be used in further calculations. The

total volume of water that the water distribution system can

135,000 m^/day 30,000 m^/day

accept from the treatment plant during the "off-peak" peri ods is equal to the total available reservoir capacity and the water consumption during that period:

Step 5: Estimate energy cost savings. a)Determine the number of"off-peak" and "on-peak" hours

that are required to supply water demand in an average week. Average weekly water consumption: 135,000 mVday * 7days = 945.000 m-

74,500 m'-t- 30,000 m3 = 104,500 m'

That comprises 77.4 percent of the average daily water consumption: (104,500 m^ / 135,000 m-') * 100% = 77.4% Therefore,in this case, the limiting factor is the maximum

Water Treatment

hourly water production of the water treatment plant and the smaller number of 74%(40 hours) will be used in calcu

lating the weekday portion of energy consumption. Consequently, the total weekly number of "off-peak" hours required to supply weekly water demand is the 40 hours calculated, plus the weekend time, or 40 hrs -I- (75.6 hrs - 54 hrs) = 61.6 hrs

That constitutes 81.48 percent of the total 75.6 hrs required to supply weekly water demand. (61.6 hrs/75.6 hrs) * 100 = 81.48%

c)Assuming that the energy consumption is proportional to the water production, the amount of energy that can be used during the "off-peak" periods under the optimum energy management program can be calculated as: 20,000,000 kW * 81.48% = 16,300,000 kW, and

during "on-peak" hours: 20,000,000 kW - 16,300,000 kW = 3,700,000 kW

The total annual energy cost would be: 16,300,000 kW * $0.033/kWh -i- 3,700,000 kW * $0.06/kWh = $759,900

Comparison of the annual energy cost under an optimized

usage of"off-peak" hours($759,000)to the unoptimized cost ($903,000)shows that the saving would be $143,100 per year, or more than 15 percent of the total annual energy cost. Limitations of the Estimate

The estimate of the energy cost savings is approximate. Some factors that would affect the actual cost saving are:

DynaSand" Filter For over 19 years, both municipalities and industry have chosen Parkson's

DynaSand Filter over ail other filters. It's a clear

favourite due to its lack

a)Daily Water Consumption Pattern. The estimate is based on an average daily water consumption and during summer months the effectiveness of usage of the "off-peak" periods would be significantly reduced. On the other hand, the number of days with water demand greater than average will be offset by the number of days with water demand below the average. During those periods more of the treated water can be produced and supplied to the distribution sys tem during the "off-peak" periods. b)Maximum Water Treattnent Plant Capacity. In the above estimate it was assumed that during the "off-peak" periods the water treatment plant worked at its maximum rated ca pacity with no equipment failure and no interruption in op eration. In reality, however, a certain amount of "off-peak" periods would be "lost" due to equipment failure or inter ruption in operation. c) Demand Charge. Demand charges constitute a signifi cant portion of an energy bill - an equivalent to 20 percent of energy cost is not uncommon. To simplify the estimate, the savings associated with reducing demand charges was not considered. However,shifting the water production and filling up reservoirs during the "off-peak" periods would further reduce energy demand and substantially increase the total "energy cost and demand charge" savings.

d) Water Distribution System. Other significant water system energy consumers which would benefit from shift ing the facility operation to "off-peak" periods are water distribution pumping stations. In some systems, they can even consume the amount of energy equivalent to the amount consumed by the water treatment plant. Although, the energy cost saving will not be equivalent to that at the water treatment plant, it still can be very significant - up to 50 percent of the total energy cost savings achieved at the water treatment plant. If the above five step, simple estimate suggests signifi cant cost savings can be achieved, a more accurate estimate can be prepared using a computer model. The authors have developed such a model using commercial spreadsheet soft ware. The model allows calculation of energy cost savings with a variation of many parameters such as changing treat ment plant capacity, total storage capacity, number of "offpeak" hours utilized with a variation of energy consumption, population and energy rates. It also allows prediction of water consumption for a specific time in the future, and help ing to develop a backwashing and maintenance schedule. Conclusions

Almost every water treatment facility has potential for energy cost savings, and substantial savings in energy costs can be achieved by changing operational practices only, without any hardware modification. The proposed easy, step-by-step method focused on en ergy cost savings associated with high lift and low lift pumps, which are the largest energy consumers and, therefore, of

fer the best potential for energy cost savings.

Prisoners in an American jail had for years been venting their frustrations by flushing a bizarre collection of items down the toilets. These items included

Subsequently, Ontario Hydro initi ated the UPP Groundwater Remediation

Project to build upon the preliminary site investigations. This is a high-profile project proceeding under the close scru tiny of the MOE, the Atomic Energy Control Board (AECB), third-party re viewers, and community stakeholders: the project must meet specific schedule requirements and is subject to detailed technical review.

The overall objectives of the project are(1)to define the extent of the groundwater tritium contamination around the

UPP,(2)to assess the potential adverse impacts of the contamination on human health and the environment through risk assessment, and (3) to identify and evaluate potential remedial measures against risk-based performance require ments and prepare a remedial action plan to address the groundwater tritium con tamination.

migration pathways of tritium contami nation and to estimate the tritium mass

in groundwater at the UPP site. As groundwater and tritium contami nation ultimately discharge to Lake Ontario, a conceptual transport model was used to assess contaminant migra tion from the UPP to define tritium load

range of groundwater flow and contami nant migration rates. Based on this model,the potential ex posure to the public from UPP groundwater contamination for past, present,

Making privately owned municipal sewage plants a reality

TheBallantrae Golf& Country Club is a 170 hectare site north

of Toronto, in York Region, in which 900 homes will be constructed over the next six to ten

years. The first phase of home building is currently in progress. These 900 homes are classified as a

condominium community. Its shared services include an 18 hole golf course, clubhouse and recreational facilities, and

a dedicated sewage treatment facility. This sewage treatment facility is unique in Ontario, as it is privately constructed and operated,and will be owned by a con dominium corporation. Construction of the sewage treatment plant is in progress, and will be complete early in 2000. Unique Servicing Requirements Schickedanz Bros., the developer, planned to develop the agricultural site

for residential use. The site is remote

from other community sewage systems, so any sewage generated from the site had to be treated and disposed of onsite. Furthermore, if conventional sep tic systems were to be used,0.5 hectare lots would be required under the Offi cial Plan. Therefore, to make the project an economic reality and to develop the site using higher densities, construction of a community sewage treatment facil ity was planned. Since the site itself has no natural

receiving water body for sewage efflu ent, it was planned that all generated ef fluent be land applied. It was also planned to utilize treated sewage efflu ent for irrigating turf on the golf course. When irrigation of the golf course was not practical, (in the wintertime, and under wet weather conditions) effluent was to be discharged to subsurface. The site is located on the Oak Ridges Moraine, where coarse soils are preva lent. Since effluent was to be directly discharged underground at times, pro tection of the groundwater aquifer was the primary concern for Ontario's Min istry of Environment. The Ministry of Environment im posed effluent criteria for the sewage treatment facility which were amongst

By James W. Lunn, P. Eng., Azurix North America

the most stringent in Ontario, including 5.6 mg/L total nitrogen, 3.6 mg/L ni trates, and 14 E. Colt per 100 mL. The concern for engineering designers was to select a process capable of meeting these stringent effluent criteria. Private Ownership Challenges In addition to meeting the technical challenges of the project, a number of hurdles had to be surmounted to get gov ernment approvals for construction of the sewage treatment facility. The sewage plant was planned to be privately owned as a shared service by the homes, as part of a condominium corporation. Under provincial legisla tion, York Region is ultimately respon sible for all community water and wastewater servicing in the area. Therefore, before the Province would give its con sent to construct the facility, an Agree ment between York Region and the de veloper had to be completed. The essence of the Agreement be tween York Region and Schickedanz Bros, is to safeguard the Region in the event it is forced to assume responsibil ity for the plant. Therefore, the Agree ment was required to ensure that the developer had sufficient funds and se curities in place for; construction of the plant, upgrades to the plant(in the event of failure to comply with the Ministry's effluent requirements), and capital re placement of the plant. Also, the Agree

ment permitted the Region the right to inspect and monitor the plant. Engineering Challenges The stringent effluent criteria im posed by the Ministry, meant that the sewage plant process would have to be carefully engineered. In particular,sew age was to be treated to a level of 5.6 mg/L total nitrogen, which meant that the sewage process would have to be capable of denitrification to reduce ni trogen levels in the effluent. Sequencing Batch Reactor (SBR) technology was selected, because the process is flexible, and sewage aeration and mixing cycles can be adjusted according to flow, and field conditions. This process flexibil ity is not provided with conventional continuous flow-through systems. Also, because of the sensitive nature

of the Oak Ridges Moraine, the sewage treatment process included continuous backwash filters, ultaviolet disinfection,

and fill and draw effluent ponds. To provide the Province with a de sign package that would be approved, the SBR technology was restricted to vendors with a proven track record of meeting these criteria, for a wide range of flows. The SBR supplier was USFilter-Jet Tec. The challenge was to ensure that a high level of treatment could be maintained during very low flow conditions when the first homes

were connected to the sewage plant.

2) Completing of the York Region Agreement. Using flow proportional SBR tech nology, the Province was satisfied that the effluent criteria were achievable.

Completion of the Agreement with York Region was not straightforward. Lendors would not issue credit until pro vincial approval was in place. The Prov ince would not issue approval until the York Region Agreement was finalized, and York Region would not finalize the Agreement until financial securities were in place. Adding to the challenge was the planned 'fast-track' schedule to get the sewage plant to construction. To move the project forward,approval was obtained of the sewage plant design, conditional upon completion of the Agreement. After conditional approval was obtained from the Province,long de livery equipment items were prepurchased. At the same time detailed de

sign was being completed, creditors put financial securities in place, and the Agreement was being prepared by York Region and the developer's solicitor. This approach effectively reduced the time to get the sewage plant to construction, and reduced the period of construction. Final approval from the Province was received shortly after the Agreement was completed, and the project immediately went to construction. The Province re

quired that a number of sewage facility components, which were engineered by different companies, be included in one approval certificate. This included the golf course irrigation system and the stormwater management ponds, which are' technically part of the effluent dis posal system.

Monitoring

UK wastewater control centre monitors

2,500 plants and stations

In 1997, Thames Water, Britain's

largest privatized water company, completed a ÂŁ3M Waste Water Control Centre, monitoring 2,500 sewage treatment works and pumping stations.

Located at the Maple Lodge works, Rickmansworth in Hertfordshire,south

ern England, the centre operates 24 hours a day identifying any potential problem in the company's 13,000 square km region within minutes. Immediate action can be taken, thereby eliminat ing the possibility of potentially serious pollution or flooding. On an average day the centre receives up to 500 alarm calls, but when it rains this can increase five times. "The

then decide if it is necessary for anyone to visit the site or if we can handle the

problem from here," says Ms Dee. The new system, commissioned in April 1997, comprises two master sta tions supplied by Serck Controls of Cov entry, central England, which supplied the software designed to interrogate all the existing out-stations, enabling the controllers located at Maple Lodge to communicate directly with them and take immediate and appropriate action. "Before the installation of the new

equipment, it was impossible for us to coordinate all the data from over 2,500 different locations. Now all the infor mation comes into the new centre on a real time basis and is also recorded on

our database," Ms Dee explains.

A'AlfaLaval

"This system also enables us to decide on priorities and whether it is necessary to send someone to the location of a prob lem,or if we can resolve it from headquar ters, where most of our trained operators have previous 'hands on' experience." Prior to the opening of the control centre, the Thames area had a telemetry system. However,the out-stations were not all connected to a single operational control complex, or directly linked. These could only handle individual geo graphical areas and pass on a limited amount of information.

"We had a TEXT transfer set-up, but this was only capable ofsaying something was wrong and where it was, but could not say exactly what the problem was and individual sites could not be interrogated directly. Master stations were only manned during the day, with out of work ing hours data being transferred to a loca tion in central London," says Ms Dee. "Operators there only received an alarm signal which told them there was something wrong. They then passed this information on to a team of stand-by out of hours coordinators who decided, based on local knowledge, whether to

call someone out to identify and rectify the fault. Moving to the new centre and coordinating all activity improved the consistency of responses. "What we did not want was to perpetu ate a system with lots of people sitting in front of VDUs in different locations. We

wanted a centralized one where a small,

dedicated team could provide a consist ent approach over a 24-hour period. The majority of the people working here have had previous hands-on operating experi ence. The shift team works on a diumal

basis,so that we have more people on duty in daytime than at night. Plus,they are all working at one central location." All the alarms on the new telemetry system are carefully monitored and prioritized, with the more important ones being dealt with immediately, while oth ers ai^e scheduled for action locally the next day. "What we are really looking for all the time are the urgent ones re quiring immediate action," says Ms Dee. Brian Dumbleton is a Chartered Civil and

Research & Development

Genetically engineered plants produce biodegradable plastic

A team ofAmerican and Swiss

"plants could,one day, become efficient biological factories, producing oils, plas tics and animal feed all in one crop." For years, scientists have known that certain bacteria make plastics naturally.

scientists is reported to have genetically engineered plants to produce biodegradable plastic. The project is a "considerable feat of genetic engineering," say the editors of the journal Nature Biotech nology. However, some are already questioning the need for the plants, say ing the world already has enough plas tic and such plants could have a serious impact on the environment if the genes ever moved into normal plants. To get the plants to produce plastic, scientists working for US biotechnology giant Monsanto, inserted four bacterial genes into plants and manipulated the metabolic pathways involved in both amino-acid and fatty-acid synthesis. Their genetically modified thale cress plants and oilseed rape produced the commercial plastic PHB V but the yields are a mere 3% of the plants' dry weight. "If enhancements in yield could be achieved," Nature Biotechnology says.

However, the microbes need to be fed a

carbon source, such as glucose, which makes bacterial plastic production even more expensive than conventional plas tic manufacturing processes using pe troleum-based products. As plants absorb carbon directly from the atmosphere,scientists believe manu facturers and farmers might turn the experiments into a lucrative business if they engineer the plastic-making bacte rial genes into plants. Until now, they have only succeeded in engineering plants that produce low-grade plastics unsuitable for use as a commodity. The Monsanto team, led by Kenneth Gruys in the US and Yves Poirier in Switzerland, engineered plants which produced a commercial quality plastic. But as they stress in their paper, yields

are very low. Much more work is needed to make the plastic plants com mercially viable. Australian researchers, working with Proctor & Gamble Co., are also trying

to produce biodegradable plastic fropi sugar cane. So are Brazilian scientists. Environmental groups in Britain have criticized the plastic plants. "There is a huge amount of research needed before anything should be contemplated that involves letting it out into the environment," said Peter Riley of Friends of the Earth, noting that using bacteria is much safer. "At least where

bacteria are used, they can be kept in a sealed vessel."

"More effort should be made to re

cycle plastic now being thrown away," he stressed, adding that "if we are wor ried about plastic, alternatives, like pa per wrapping, might be examined more carefully." "There is already a natural plastic called cellulose," he said. ❖

table. Until now,there had been no prac tical way to clean this type of effluent. In its first nine months of use at

tory is cleaning a heavily contaminated industrial site in Visalia,

California, in a few years, not centuries, as would be required using conventional methods. Called dynamic underground stripping, this new technique heats soil and groundwater to both remove under ground contaminants and destroy them in place. Southern California Edison put this technology to work at its former Visalia pole yard, a four-acre site, used from the 1920s to 1980 to treat power poles with preservatives such as creosote and "penta"(pentachlorophenol), dissolved in diesel fuel. Over the years, residues leaked into the ground and contaminated the groundwater. These wood preservatives are particu larly difficult to clean because they are more dense than water and tend to sink

through the soil down through the water

Visalia, dynamic underground stripping removed, or destroyed in place, an amount of contaminants that would have

required more than 1,000 years with tra ditional pump-and-treat cleanup, the kind used at the site since 1975.

With pump-and-treat, essentially pumping up polluted water and clean ing it at the surface with state-of-the-art filtration, about 275 pounds ofcontami nants were removed during one ninemonth period. During a similar amount of time, dynamic underground stripping removed some 540,000 pounds of con taminants - nearly 2,000 times more. Since the clean-up started in June 1997,engineers have removed a total of 902,000 pounds of contaminants at the Visalia site.

It is believed by some experts that the new technology could be used to efficiently and economically destroy the

pollutants found at about one-fourth of the nation's 1,300 Superfund sites. Dynamic underground stripping acts in two ways. One is by using steam heat and pressure to drive contaminants to extraction wells, where they are easily removed from the soil and water. The

other is by allowing heat and forced air to chemically break down many con taminants in place,converting them into harmless compounds. Another vital component of dynamic underground stripping is the imaging technology called electrical resistance tomography. This Lawrence Livermore innovation was refined by SteamTech Environmental Services of Bakersfield,

Califomia,during work at the Visalia site. The technology uses sensors to meas ure electric resistance and temperatures underground to create computer-based, three-dimensional images that show the location of the contaminants and their

temperature measurements. Those im ages allow specialists on the surface to

Pumping

Centrifugal pump selection Some important, but perhaps overlooked, considerations

ThroughoutCanada centrifugal

pumps, which use an impeller to produce internal pressure and create high velocities that transfer fluids, are the most commonly specified pumps for sanitary wastewater transfer applications. Since the late 1940s when the first actual centrifugal pump exclusively designed for sewage transfer was introduced, several designs have emerged. Variations have been made in impel ler design - including the use of semiopen,or closed impellers; shaft con figuration, such as vertical or hori zontal; and priming mechanisms, such as conventional flooded-suc-

Improper application can also result in excessive stresses, cavitation or accel

erated deterioration of a pump's inter nal components. Therefore,it is always important to analyze the pump curves provided by suppliers. Published pump curves can also be used to determine a pump's efficiency under various operating conditions. Pumping efficiencies of different pumps can be compared when the brake horse power and motor horsepower values are known. With this information, certain

Most centrifugal pumps have two integral parts: a rotating and a station ary element. The rotating element in cludes the impeller and pump shaft, and the stationary element includes the vo lute and a stuffing box, which contains the mechanical seal and housing. Be cause of the variation in designs, inter nal components and parts also can dif fer in materials of construction. Better

Pumping tually wear out, although it takes up to seven years for some pumps. Mechani cal seals that are not visible or easily serv iced should be replaced every one to two years to avoid catastrophic failure. Seal-face cooling is essential for pro longed service life. Composed of a ro tating part and a stationary part that "mate" at their "faces"(or facing ends), seals must be lubricated with water, oil

or grease to prevent rubbing and subse quent wearing. The properties of these fluids create enough pressure to lift the rotating element off of the stationary element. Heat causes seal failure by raising the temperature of any lubricant to the point where it starts evaporating. The evaporation of the lubricant reduces its viscosity and the necessary pressure to create a safe running clearance. Drag ging results, which produces even more heat and eventual failure. Water from the volute is an ideal lubricant because

it dissipates heat better. Most seal housings are composed of cast iron, which is a poor conductor of heat. Even though they are less com mon, a bronze seal housing will dissi pate heat much better. Because of the running speeds that

Capital Costs Considerations Several pump station designs have emerged from the conventional under ground (dry-pit) station in previous years, including submersible (wet-pit) pumps and above-grade/suction lift sta tions. Because of the qualitative design variation in today's pump stations, closer examination of the station's capi tal cost is necessary. Each pump station category has par ticular advantages and disadvantages when it comes to capital investment, depending on the application. When making buying decisions for pump sta tions, map out your potential for the "hidden" costs by figuring the total in

While the bearing size cannot be adjusted, bearing con struction can affect pump durability. Certainly, heavy-duty (or large) bearings can handle more thrust and last longer. A bearing with half of its allowable load will last eight times longer than a fully loaded bearing. Bearing failure can stem from im proper maintenance or inadequate lubri cation. It will initially result in motor lockup and can lead to pump failure if not resolved. While it usually is not nec essary to lubricate bearings more than twice a year, lubrication can be easily overlooked and incorrectly handled. Two symptoms of bearing failure as a re

An above-grade station with the smaller wet well does not require a valve vault.

Maintenance

Earlier, it was mentioned that routine

maintenance is important for preserving the successful service life of a wastewater

pump. Therefore,the ease of maintenance or accessibility to the pump is a key con sideration for pump station consideration. Ask yourself these questions: How does the pump station installation simplify maintenance concems? Does the station

facilitate easy access to the pump, or at least provide adequate sensors,instrumen tation or telemetry to indicate problems? What are the potential confined space con siderations and necessities, if any? According to the Ontario Ministry of Labour, a confined space is defined as "an enclosed structure with limited ac

cess, open-top structures that are deep enough to require special means of en try and exit, and other confined spaces

Concrete Pipe

such as ducts and tunnels."

For example, pump stations with ex ternal valve vaults often qualify as a confined space, presenting two common safety concems-the limited entry to the valve vault and the danger of explosion from the combination of methane gas and electrical equipment. For any con fined space entry, a minimum of two workers must be present for safety rea sons, reducing man-hour efficiency. Regardless, potential confined-space requirements saddle industrial and mu nicipal facilities with additional paper work and thorough training. Workers must also be suited with appropriate safety equipment, which can be costly to purchase and maintain. Obviously, it is more feasible to minimize confined space entry when possible. There is universal agreement among safety specialists that it is better to eliminate hazardous work

conditions through engineering than it is to deal with hazards head-on.

means if the bedding and backfill hasn't been properly executed, the pipe will shift. With less inspections and reduced on site testing, that's a real problem. Consider concrete pipe. You bury it and forget about it. It's your project. Now turn your mind to the sweeter things in life...

Arabian Gulf turning hot, salty, and oily Shoals of fish are dying in the northern part of the Arabian Gulf as the salt level soars and the water temperature rises to a blistering 38°C (100.4°F). The first fish carcasses were noticed in mid-

September. A leading Arab environmental or ganization warns that this is the result of the global warming compounded by indiscriminate dumping of wastewater in the region by oil companies and un checked oil seepage into this body of water, also known as the Persian Gulf.

Though the leading oil companies in the Gulf claim they are following a "clean Gulf" policy, and are trying to produce "energy with responsibility". Dr. Abdul Rahman A1 Awadi,executive

secretary of the Regional Organization for the Protection of the Marine Envi

The off-shore oil rigs operating in the Gulf produce between 30,000 and 40,000 barrels of oil per day. Environ mentalists have been warning that some has been spilling into the sea because of seepages in the sea bed, cracks in rigs, illegal discharges by oil companies and vessels and accidental spills.

the outcome of regulations announced by EPA June 29,1989,generally referred to as the Surface Water Treatment Rule

(SWRT). These regulations specify criteria for determining filtration as a water treatment technique for public water systems.

The NYC watershed is approxi mately 2,000 square miles, and supplies NYC with up to 1.4 billion (US) gal lons of water per day. The cost of such a plant was estimated to be (US) $6,000,000,000. Capital cost and fi nancing fees were prohibitive, so an al ternative was pursued. The end-result was an agreement termed Filtration Avoidance Determination (FAD). The FAD was extensive and included reser

Cryptosporidium, Giardia, and phos phorus from all wastewater plants in the NYC watershed.

Wastewater treatment plant upgrades There are approximately 100 wastewater treatment plants (WWTPs) that discharge into tributaries that lead to NYC reservoirs. It was determined that the effluent from these WWTPs had to

Various coagulants were tried, but PACl(poly-aluminum chloride) was the most successful in the project. On average, the process reduced the phos phorus limit entering the filter at 2.33 mg/L to 0.05 mg/L. This was accom plished in conjunction with average TSS (Total Suspended Solids) loadings of 42.5 mg/L. Later, a second pilot project was per formed in Stamford, New York in 1996

to further evaluate the new technology's ability to remove protozoa. The test began in October - during a warm Fall season. Two weeks into the pilot, cold weather set in. The process began to experience problems with turbidity. More PACl was added with little, if any, improvement. A Parkson representative with experience in water applications in Quebec, suggested trying a coagulant

Turbidities in the Stam ford wastewater soon began to return to the 0.15 NTU average experienced prior to the drop in water temperature. A particle counter was used to optimize the dosing rate (see graph). Once optimized, the dosage required lit tle adjustment. PASS was not as sensi tive to alkalinity, pH, temperature or fluctuations in TSS and phosphorus. This characteristic was important since the water quality requirements of the NYC watershed required the wastewater operator to become (in essence) a water plant operator. The fewer the adjust ments the better.

The EPA and NYC Department of Environmen tal Protection worked together to de velop a new, more rigorous, spike chal lenge protocol. Twelve spike challenges would have to be performed to deter mine if DualSand filters were equiva lent to microfiltration in the removal of

Beneath this goodwill toward engineers and technology, however, lies a disturb ing problem - Americans, particularly women,generally feel uninformed about engineers and engineering.

Public Perception "They revolutionized medicine with pacemakers and MRI scanners. They changed the world with the develop ment of television and the transistor, computers and the Internet. They introduced new concepts in transportation, power,satellite communications,earthquake-resistant build ings, and strain-resistant crops by applying scientific dis coveries to human needs. Despite these contributions to society, this 'stealth profession', whose membership num bers more than two million in the United States alone, re

mains largely invisible." Sloan continued: "As our nation's workforce continues

the transition from one which is predominantly male and Caucasian to one which will be majority female and Afri can-American,Asian, and Hispanic, the price we pay in our society for engineers having worked in such obscurity may not be known for another generation. But it is clear to me today that we, as an engineering community,in partnership with the media and our educational system, must act now to increase society's understanding of engineering." Underscoring the importance of this action, Sloan noted

....we, as an engineering community, in

partnership with the media and our educa tional system, must act now to increase society's understanding of engineering. that although women comprise 53.7% of the undergraduate student population, only 19.4% of the students enrolled in undergraduate engineering programs are female. Sloan also pointed to recent data published by AAES's Engineering Workforce Commission (EWC), which revealed that enrollments among African-Americans in undergraduate en

gineering programs declined in 1997 despite an overall in crease in first-year degree programs. These enrollments, however, must be measured against the backdrop of a na tionwide decline in the number of students receiving under graduate engineering degrees over the last decade. Since 1987, the number has fallen by more than 14%. Public Attitudes toward Engineers and Engineering Despite the low level of public awareness about engi neering, the survey revealed that many parents would be pleased if their children became engineers. An earlier Harris Poll revealed that engineers hold relatively high prestige compared to other professions but fall considerably below scientists, teachers and physicians. Joseph Bordogna, acting deputy director of the National Science Foundation and president ofThe Institute of Electri cal and Electronics Engineers (IEEE), made the following remai'ks in response to the results: "Engineers will create and manage new systems for civil infrastructure, manufacturing, communications, health care delivery, infoimation manage ment, environmental conservation and monitoring, and eve rything else that makes modem society function. "If we are to attract our best and brightest students to engineering careers, we must ensure that their concern for human compassion and environmental stewardship as well as their capacity for creating economic wealth is understood and respected by our citizens and institutions. Our ability

to improve public understanding of engineering will not only raise the level of interest among our nation's youth in engi neering, but elicit public support as well for the efforts of these engineers to simultaneously improve our world's Environmental Science & Engineering, January 2000

economy and ecology." Public Perception: Tbe Media and Engineering

When asked to rate the quality of media coverage of sci ence, technology, engineering, and medical discoveries, more than 69% of the survey respondents assigned "fair" or "poor" grades to engineering reporting while less than 3% gave the media an "excellent" score. Among college gradu ates and those with incomes of $75,000 or more, 85% and

80% of the respondents respectively assigned scores of "fair" and "poor" to thejob the media does in covering engineering. When the pollsters asked which professionals - scien tists, technicians, or engineers - respondents "mostly asso ciated" with an activity, engineers were frequently underes timated in their roles. In areas where there exists a strong engineering element such as "working in space," "develop ing new forms ofenergy" and "creating new materials," sci entists were more often cited than engineers. Sloan noted: "Engineering is sometimes thought of as applied science but engineering is far more. The essence of engineering is design and making things happen for the ben efit of humanity. Engineers do basic and applied research. But all too often, engineers who conduct research are generically identified as 'scientists' or 'researchers'. It is no more appropriate for someone to describe an engineer as a 'researcher' as it would be for us to depict a surgeon as a 'health care worker'.

"We,as an engineering community, must speak with pride about our engineers and our engineering achievements and not allow our profession to be wholly subsumed within the lexicon of'science and technology'." â?&#x2013;

Liquid Macrofiitration Equipment

2000

Salesoffilter pres es,beltfilters, and other liquid macrofiitration equipment will rise from $2

billion in 1999 to $2.6 billion in 2003. Add another $1.1 billion for

replacement media and the combined equipment and media market in 2003 will exceed $3.7 billion (all $US). This is the forecast in a new report from the Mcllvaine Company entitled: Liquid Filtration and Media World Markets Addendum 1999 to 2003.

Liquid macrofiitration is the heavy duty end of the filtration business. It cov ers the efficiertcy range between screens and membranes. It deals with large sol ids quantities. Therefore, the specific equipment in this category (sand filters, belt presses,filter presses,leaffilters, bag filters, and gravity belt filters) are large and rugged. They are used in municipal water and wastewater plants, chemical, mining, and other industries with solid/ liquid separation needs. The largest segment will be granular media filters (sand and other granular materials) at just under $800 million. The filter press segment will be the sec ond largest in 2003 with equipment rev enues of $500 million and filter cloth revenues of $255 million.

According to The Mcllvaine Com

pany, mining and chemicals are two of the largest applications for liquid macro fiitration. The growth areas for both these industries are in developing countries. As a result, the US market share will fall from 22% to 20% in the next four years.

2001

2002

2003

Japan's share will fall from 9% to 8 1/ 2%. China,on the other hand, will enjoy a 12% market share in 2003,up from 10% at present. Australia will have a 4% mar ket share in 2003. This will be greater than the share for Italy or France. Chile will have a 1 1/2% share. This will be more than the share for either the Neth erlands or Poland.

Until recently, the supplier industry was fragmented with no dominant com pany. However, in the last few years, USFilter(now part of Vivendi) has pur chased filter press, belt press, and sand filter companies. Even so, its present market share is well below 40% in the US and below 20% worldwide. The near

est competitor has less than a 10% mar ket share. There are more than 1,000

companies around the world designing and supplying liquid macrofiitration equipment. Most have narrow equip ment, industry, and geographical focus. There is no dominant supplier of filter media.

There have been more significant developments in media than in equip ment in recent years. Coated fabrics have improved efficiency and cake re lease. Continued fabric improvements will be necessary to counter improve ments in competitive devices. For ex ample, centrifuges compete with belt presses. The latest generation of centri fuges can provide a drier municipal sew age sludge than can the belt press. For information. E-mail: editorÂŽ

Noise Pollution

High tech solutions for an Insidious problem

TPreduce the exposure ofneigh

boring buildings to noise from roads and rail-ways, French companies have tumed to three

of absorbent mineral wool. The walls

produced using them are attractive while reducing noise levels. Growing environmental awareness in

methods: noise reduction at the source,

France has also resulted in the use of

insulating buildings facing the noise, and introducing acoustic screening along

sustainable materials in public works projects, and the growing use of wood for anti-noise screening. Recycling while reducing noise is a technique developed and patented by Paris-based Acial. This company makes

transport routes.

Although the country was slow to in troduce effective anti-noise legislation, on December 31, 1992, a law was passed that allowed for a delay of ten years in reducing road "blackspots", where neighboring noise levels exceeded 65 dB(A). Seven million people in France are directly affected. Conscious of the potential market, construction compa nies have developed a number of effec tive noise reduction solutions that have

a good visual appearance. Concrete, wood-concrete, cork-con

crete, expanded metal, glass and Altuglass, the range of materials used by French manufacturers is extremely var ied. Included in this list are specially built clay bricks offered by Guiraud Freres of Toulouse, the only manufac turer in the world offering large dimen sion self-supporting clay bricks. Meas uring 8.5 feet long, two feet wide, and eight inches thick, these bricks are placed horizontally or vertically, have a perforated facing, and incorporate a mat

use of used tires, which are cut in two

and positioned in modular perforated steel enclosures. The screening pro duced in this way provides a high level of sound absorption while offering an original solution to the problem of re cycling mountains of scrap tires. The KIOSK agency in Grenoble has developed expertise in the creation of screening that is transparent or profiled like aircraft wings. These are built this way to take advantage of natural light and avoid creating a visual obstacle for neighboring dwellings. Three factors in reducing noise Whatever material is used, the acous

tic efficiency of anti-noise screening depends on three factors: •It must be sufficiently heavy to reduce direct sound transmission, with a mini

mum surface density of six pounds per square foot for a minimum transmission loss index of 30 dB(A), as measured in

a laboratory. • It must be located close to the noise

source, overlap the area to be protected

by at least 500 feet on each side, and be sufficiently high (seven to thirty-three feet), depending on the site and the traf fic, to reduce the intensity of diffracted waves. This is important as sound, par ticularly at the low frequencies predomi nant in road noise, can pass around or ignore banders. • It must not reflect the incident sound

energy onto dwellings that may be op posite the sound barrier. Reflecting screening should,in this case, always be tilted by about ten degrees towards the bordering land so as to reflect the sound upwards. Absorbent screening on the other hand should be vertical.

In the best cases, the final reduction achieved is not more than 10 dB(A),

which considering the logarithmic scale used for decibels, is equivalent to a noise reduction of about 50%. This result as

sumes a high level of technical exper tise at all stages(manufacture, analysis, design, installation, etc.). The widespread availability of com puter tools for acoustic simulation ena bles better design and installation of anti-noise screening. Studies using physical models, which take a long time and are expensive, have been superseded by computer simulation. The design of acoustic screening is now performed using computer modeling tools. These take into account the effects of propa gation depending on the weather (wind and temperature) and the type of soil (absorbing or reflecting) at the site. ❖
