Infrastructure

Standing the test of time after 75 years

Constructed between 1917

and 1919 as part of Winni peg's Shoal Lake aqueduct system, the Branch I aque duct provides one of the two final links between the Deacon reservoir on the

city's outskirts and the urban distribu tion system. The line consists of some 18.6 km of

precast reinforced concrete pipe and over 300 metres of concrete encased cast

iron pipes that run under the Red River; it was originally designed to operate at a full capacity of 250 ML/d. It has been operating at about half that rate since commissioning, and only recently have water demand studies identified the need

for maximum design operation. Natu rally, the City had a major concern;.af ter 75 years would the pipes still be able to operate at increased pressures? In a project that parallels the main Shoal Lake aqueduct assessment and rehabilitation, CH2M Gore & Storrie Limited, in association with UMA

Engineering Ltd., went straight to work to find the answer.

Approximately 400 m of the original 1676 mm diameter pipe,(or about 200 pipe sections) designed to operate un der a 12.2 m head, were replaced in 1966 to accommodate construction of the Red

River floodway. Four of the salvaged sections were located in 1994 and pro vided a unique opportunity for full-scale hydrostatic testing. As part of an over all structural assessment, full-scale de

structive testing was conducted on the salvaged pipe sections in order to con firm the original design strength of the pipe,to determine the impact of reduced wall thickness by simulating external

sulfate attack on the concrete, and to

provide experimental data for verifica tion of a finite element analysis model. The test setup consisted of the con crete test pipe, concrete bulkheads(one for each end of the pipe), a water buffer tank, and an air compressor. The buffer tank was used to supply water to the test pipe in case of leakage. Compressed air was introduced to the buffer tank from

the top. The concrete bulkheads were clamped to the ends of the pipe with eight tie-rods. A two-part polyurethane was injected in the gaps between the ends of the pipe and concrete bulkheads to provide a flexible watertight seal

ing. Dial gauges were installed on the ends of the test pipe to measure radial displacements of the test pipe for the purpose of verifying data collected from internal sensors.

The entire test was divided into 3

phases. Phase 1 was performed to test the pipe up to 1.2 times(ASTM C361M, 1993) the anticipated maximum work ing pressure (including 50% allowance for transients). Phase 2 tested the pipe up to pressures twice the maximum anticipated transient pressure in the pipe line. Phase 3 implemented the removal of layers of external concrete by water jetting, simulating sulfate attack, that

exposed surface. Phase 3 testing was carried out at the Phase 1 pressure for 10, 20 and 38 mm of concrete removal. At a depth of 38 mm into the pipe, the outside surface of the outer reinforcing steel was exposed. The intemal pressure was then increased to an ultimate pressure of 600 kPa. A minimum factor of safety of 3.3 was confirmed under the internal loading condition. Although a reduction in wall

To prevent air inclusion in the test pipe, the inlet hose was connected to the pipe at its invert elevation, and the out let hose at its obvert elevation. A regu lator was used in the feed line to control

Why is aluminum added to drinking water during water treatment? Waterbome micro-organisms(bacte ria, viruses, protozoa) are a very serious health risk. Aluminum compounds are used in drinking water treatment to re move these harmful micro-organisms and particles that can protect them from disinfection, by coagulating them, or causing them to clump together into larger particles. These large particles are then re moved by sedimentation and filtration. Aluminum-based compounds also re move naturally occurring organic mat

Is municipal drinking water safe? The water provided by municipal water suppliers is safe. First, the water usually meets all provincial guidelines for purity. Guidelines are very stringent and are designed to protect human health. Second, municipal water sup pliers monitor their water on a regular basis to ensure that the guidelines are met; in most municipalities, this in cludes an attempt to keep aluminum lev els low, despite the current lack of a guideline for aluminum. Finally, water treatment processes are carefully monitored and controlled to ensure that any process failure is imme diately detected and corrected. What is Health Canada doing to ensure the safety of our drinking water? The major responsibility for ensur ing that drinking water is safe lies with the provinces. A consistent approach to improving drinking water quality is pro vided by Health Canada's Guidelinesfor Canadian Drinking Water Quality(soon to include the aluminum guideline), which are designed to ensure that Cana dians have access to wholesome and safe

TheCommitteeon Environmen

the following considerations: 1. Because of the questionable signifi cance of the toxicity end-point, the guideline was established at the lowest practicable level of 3.0 mg/L. The Prac tical Quantitations Limit(PQL)for chlo ramines is approximately 0.1-0.2 mg/L, well below the proposed MAC. How ever, many small municipalities do not have the capacity to measure individual chloramines or total chloramines down

to the sub-milligram level, and 3.0 mg/ L is a realistic PQL in these cases. 2. This level is considered to be close to the MAC calculated from the NOEL for

monochloramine, in view of the uncer tainties associated with this calculation.

"The

both ancient and modem sediments, the researchers meas

ured larger amounts of phosphoms in sediments produced during conditions in which oxygen levels in the surrounding ocean water were high. Conversely,low levels of water oxygenation corresponded to reduced amounts of phosphorus stored in the sediments.

"We find that when the oceans are fully oxygenated, the sediments tend to be more effective sinks for phosphorus than when the oceanic waters are depleted in oxygen", explained Van Cappellen. "This is critical because the productivity of the oceans appears to be limited by how much bioavailable phosphoms is available." Well-known oxygen-dependent chemical processes centered on iron oxides account for a portion of the phospho ms uptake. But the two researchers believe a biological fac tor-likely bacteria living in the ocean floor sediments-also plays a significant role. "Iron alone cannot explain what we are seeing". Van Cappellen said. "We propose that the bacte ria living in the top layers of sediments can be efficient scav engers of phosphoms, though this scavenging seems to be linked to the availability of oxygen. These bacteria can switch from one type of energy cycle to another, depending on whether they have enough oxygen. Microbial physiology therefore, may play a role in how efficiently phosphorus is

removed from the water column." Such microbial effect has

been observed in freshwater lakes, and also in the operation of wastewater treatment plants, where high levels of oxygenation result in improved removal of phosphates, he noted. With support from the (U.S.) National Science Founda tion(NSF)and the American Chemical Society(ACS),Ingall and Van Cappellen plan additional field research aimed at testing their model. Over geologic time, oxygen levels in ocean water are tied closely to the amount of oxygen in the atmosphere. This pro posed feedback system would,therefore,counter fluctuations in atmospheric oxygen caused by changes in oxygen con sumption during weathering of minerals and old organic mat ter exposed on land. Because the marine plants also remove carbon dioxide during the photosynthesis process, the pro posed feedback cycle could help researchers attempting to better understand other aspects of global climate change. The model advanced by Van Cappellen and Ingall may also help explain the environmental stability that would have

been required for life to thrive and evolve on the earth during the past 500 million years. Without steady levels of atmos pheric oxygen, higher forms of life would have been unable to survive. The work may also lead reseai'chers to more closely examine the role of phosphorus in the environment. Because the nutrient exists in low concentrations in sediments, it has

been difficult to measure and often ignored by scientists meas uring carbon, oxygen, sulfur and iron - whose effects have been more completely documented. Van Cappellen notes that the proposed feedback mecha nism shows the interdependence of seemingly-unrelated parts of the global system. "You really cannot think about the evo lution of the earth or the atmosphere without looking at the links to biology", he said. "You must consider how the bio

sphere interacts with the geosphere. I think this shows that life has developed ways of compensating for any drastic changes in its environment."

â&#x20AC;˘ Canadian pulp and paper 0 producers are helping shape an international standard for sus

tainable forest management based on ISO 14000.

â&#x20AC;˘ Paper producers are imple menting voluntary action plans to preserve biodiversity and reduce greenhouse gas emissions linked to global warming. In the case of greenhouse gas reduction targets, pulp and Canada may have vast forests but a new generation of pulp paper is a leading industrial and paper technologies Is needed to preserve them.

further reductions in CO^ emissions. The five-year research program will be all-encompassing, developing tech nologies which can be retrofitted to any type of mill: pulp, integrated paper or board mills and other non-integrated paper mills.

Let's end the confusion

There is only one Toronto

Environmental Tradeshow & Conference

May 6 & 7,1997

International Centre, Mississauga, Ontario 10 YEARS OF SOLID GROWTH There is only one Toronto Environmental Tradeshow 6s: Conference - that hasn't changed. This Show is Canada's leading source of practical and cost-effective solutions to environmental problems. This year, it will he held again in the International Centre in Mississauga at the same time in May as it has for the past 10 years. SOUTHEX HAS MADE A GOOD SHOW EVEN BETTER

There has heen one significant change however. In 1995, SOUTHEX EXHIBITIONS purchased the Show from the founder and made a good Show even better. ANGUS REID RESEARCH TELLS A COMPELLING STORY Attendee endorsement of the Southex changes are reflected in the ANGUS REID 1996 on-site research that told us; • 71% attend no other environmental show

• 68% left the show planning to make a major purchase • 51% found at least one new supplier • 71% have an important role in the purchase decisions for their company The Angus Reid research also told us that attendees would prefer a number of highly relevant, information-packed educational seminars, rather than a formal conference. In 1997, we will he offering leading technology and new product seminars along with a series of legislative sessions that will help the industry understand the way it's going to he required to do business in the future. Seminars will he provided at an attractive cost to participants. All in all, the 1997 Show is going to be the most significant environmental industry event that you've ever heen involved in.

began production at its newly relocated and expanded plant

in Slemon Park,Summerside,

Prince Edward Island, in the spring of 1996. The new plant, which produces potato chips and other snack foods, utilizes an anaerobic/aerobic waste

treatment system to pretreat its wastewater before discharging to the Slemon Park sewage treatment plant. ADI Systems Inc. was chosen for this design-build bid call that included a performance guarantee along with a tight schedule. Several waste treatment alternatives

were considered during the preliminary planning stages for the new plant. It was concluded that a combination of in-plant screening and settling followed by anaerobic pretreatment and a simple aerobic system would be the most costeffective means of meeting the discharge limits. The anaerobic treatment tech

production. Because this digester is a "low-rate" anaerobic system, it has the inherent ability to digest high concen trations of suspended solids(SS);fat, oil, and grease (FOG); and recycled biosolids produced in the aerobic polish ing step, with minimal sludge and/or scum accumulation - an important fac tor given the characteristics of Small Fry's wastewater. Furthermore, the re actor at Small Fry has sufficient sludge storage capacity to hold sludge for sev eral months at a time, allowing the sta bilized sludge to be disposed of by di rect land application during the most appropriate times of the year(spring and fall). System Design Criteria The design wastewater characteris tics through each stage of the treatment

the screenings for animal feed. The wastewater that passes through the screen is directed to a different tote box where starch and mud settle out. The effluent end of this tote box has a

weir for uniform removal of the efflu ent and a removable section of flexible

hose that conveys the screened and set tled wastewater to a floor flume which

discharges into the main sump in-plant. Anaerobic System The anaerobic BVF reactor is the

heart of the treatment system. It serves to remove the majority of both the dis solved organics and suspended solids from the wastewater. It also digests the biosolids produced in the aerobic step of the treatment train. The majority of the organic matter which is removed (over 90 percent) gets converted to

Industrial Wastewaters, cont'd. spring and fall. Aerobic System The aerobic system consists of a 600 m^ bolted steel tank (2.0 d HRT) equipped with three 10 hp high-speed floating aerators. The aeration tank is followed by a simple conical-bottomed clarifier, 6.6 m diam. The aeration sys tem can either be operated in activated sludge mode with sludge recirculation from the clarifier to the aeration tank or

Stormwater Management

Confinement system reduces erosion

Alldevelopments can impact on lands abutting them but a residential subdivision in

Hull, Quebec gives an inter esting overview of problems faced and overcome.

Stormwater runoff patterns were sub stantially altered by the development after construction of the subdivision started in 1992. Much of the runoff is

now directed into the existing Ruisseau Leamy channel, increasing normal storm flow volumes to 6.98 cubic me

tres per second. Peak storm flows have increased to 10.45 cubic metres per sec ond, with a velocity of 3.48 metres per second.

The increased flows resulted in sig nificant stream bank erosion taking place in an area downstream from the new subdivision where the Ruisseau

was a loss of valuable soil and a nega tive impact on water quality. Responsibility for corrective action fell upon the City of Hull, who retained the consulting engineering firm of JeanLuc Allary and Associates to find an erosion mitigating solution. Under the terms of reference, property owners in the affected area would have input into the decision-making process. A so lution that blended easily into the sur rounding native woodlands and vegeta tion was mandatory. Compounding the situation was the fact that the existing soils in the channel were predominantly soft, weak clays. These clays are ex tremely prone to frost heave and differ

The system was chosen for two pri mary reasons,(i) flexibility in soft soil conditions and,(ii) the ability to provide a visually attractive, vegetated solution. Geoweb CCS possesses a three di mensional stmcture manufactured from

high density polyethylene. The CCS permits the use of common infill mate rials in demanding load support, soil stabilization and erosion control appli cations. On erosion control projects and depending upon conditions,the Geoweb reduces rilling and piping, increases flow capacity and prevents the build up of hydrostatic pressure. Its cellular con-

The 1.6 metre high retaining wall was designed as a grav ity wall, with a 1:6 H;V slope, using con ventional retaining wall design method ology. In addition to the vegetated face, the consultant specified that the 200 mm deep exposed cell walls should be green in colour in order to better blend with

MISA monitoring - what did it reaiiy cost? monitoring efforts were used to deter mine which pollution parameters would have limits set in each sector and to help set the maximum allowable concentra

Costs to develop and imple

ment new programs and poli cies are a major concern. In recognition of this concern, staff in the Ontario Ministry of Environ ment and Energy(MGEE)carry out eco nomic assessments of all major environ mental initiatives prior to their imple mentation.

After a new program or regulation is implemented, the actual expenditures incurred are seldom, if ever, monitored.

However, in the case of the MunicipalIndustrial Strategy for Abatement (MISA) program, a survey was com pleted to determine how much regulated plants actually spent to comply with monitoring and reporting requirements. To our knowledge, this is the first time that the actual costs of a regulatory pro gram have been surveyed in Ontario. Data on actual costs of regulatory programs can be used to assess the ac curacy of cost estimating procedures; to evaluate the true effects of regulatory programs on regulated firms and indus tries. Such data can also be compared with similar data from otherjurisdictions for competitiveness purposes. Finally, these data indicate the magnitude and extent of certain components of the en vironmental protection industry. In this article, we assess the accuracy

of pre-program cost estimates for the MISA program. We also summarize findings from the survey including total costs per industrial sector, employment implications and the use of consultants. Details of the survey and analyses of

more "conventional" organic and inor ganic contaminants such as BOD,TSS data can be found in a June 1996 study. Water Pollution Monitoring Costs in Ontario- Comparison ofEstimated and Actual Costs, conducted by the Minis try of the Environment and Energy,

total monitoring costs to be $73.7 mil lion for 237 plants, or $311,100 per plant. Estimated capital expenses for equipment and installations amounted to 35% of this total. Effluent sampling ac counted for $25.6 million of total esti

mated monitoring expenses followed by $16.2 million for routine analyses,$12.9 million for flow measurement, $11.8 million for complete analyses of com

plex organics ("characterization analy

ses") and $5.1 million for data storage and reporting and $1.6 million for toxicity testing. The highest estimated monitoring costs were for 7 iron and steel mills, av

eraging $1.2 million per plant or

$732,000 per plant for capital and $464,000 per plant for operating costs. At the other end of the spectrum, the 51 industrial minerals plants that were tar geted in the program were estimated to

incur about $38,900 per plant. Reported Costs of Monitoring Activities

The monitoring cost survey was de veloped by staff in the Economic Serv ices Branch of the MOEE. The ques

Ontario Hydro reported the largest total sector monitoring expenditures of $22.3 million for 20 of its fossil, nuclear and hydraulic generating stations. (An additional $200,000 was spent at 2 Atomic Energy of Canada plants.) The single reporting iron and steel plant had the largest total expenditure per plant of $1.7 million. Metal casting foundries spent the lowest per plant; $21,900. Of the 5 key monitoring functions, the most money was spent on sampling at 27%($14.2 million) of the total. Ana lytical testing followed at 22% ($11.9 million), 20% ($10.4 million) for flow measurement,9.5%($5 million)for re porting and 2.2% ($1.1 million) for training, seminars and transportation. The 117 responding plants reported 210 consulting contracts with 55 firms at $42,000 per contract. About63%($6.4 million) of the value of consultant con

tracts were for chemical analyses. Table 2 shows that responding com panies hired a total of 106 persons to perform in-house monitoring activities. Of these, 62 were permanent positions and 44 were part-time or temporary jobs over the year-long program period. These jobs translated into 343,400 person-hours of work to perform in-

plant. The per-plant expenditure is 45% higher than the $311,000 per plant ex pense estimated prior to implementing the monitoring regulations. Total re ported capital and operating costs were split 50-50. Actual operating expendi tures included $10.2 million to hire ex

ternal consultants. Total capital and op erating costs per-plant amounted to

$224,000 and $228,000 respectively. 92

Comparison of Estimated and Reported Monitoring Costs Of the 117 respondents to the survey, 99 were plants for which pre-regulation cost estimates had been prepared. Dur ing development of the monitoring regu lations and the year-long monitoring period, a small number of plants sub ject to the regulations closed and sev eral new plants were opened or were discovered for which cost estimates

were not prepared. All comparisons of actual and estimated costs are based on

these 99 plants. Table 4 shows that, in the aggregate, costs were 'under-estimated' as com

pared to reported monitoring costs for the 99 plants. Total estimated capital costs ($16.4 million) were 36% ($9.1 million) lower than the reported capital

costs of $25.5 million. Estimated oper ating costs($27.2 million) are 7%($2.0 million) lower than total reported oper ating costs of $25.4 million. On the other hand, total monitoring costs were 'over-estimated'for 5 sectors;

pulp and paper, iron and steel, metal mining, industrial minerals and inor ganic chemicals. The largest over-esti mate amounts to 2.5 times the actual

costs for the mining sector. Capital costs were 'under-estimated' by 6% to 61% for all sectors except

Table 3 also shows that costs per person-hour range from $63.4 in the petroleum sector to $161.8 in the metal casting sector. This wide range in cost per person-hour appears to be due in part to the degree of automation and capital investments made by regulated compa nies.

metal mining and iron and steel. Capi tal costs for Ontario Hydro were under estimated by 61%. According to Min istry officials, this discrepancy was due to changes in the monitoring require ments after pre-regulation monitoring cost estimates were prepared. Further more, errors in capital cost estimation were often due to uncertainties in the

costs of installing instrumentation and other structural facilities.

Over-estimation of operating costs amounted to 185% for the mining sec tor. About 74% of this difference is due to over-estimation of costs to hire con sultants.

Ratios of estimated-to-actual expen ditures for monitoring activities by plant show the range of error varied from 40%/+19% for oil refineries to -i-65%/

-1-1,053% for mining sites. Despite these error ranges, statistical tests of signifi cance indicate that monitoring cost es timates for petroleum refineries, pulp and paper mills and organic and inor ganic chemical plants were statistically significant estimators of actual costs. Details of these tests and other ana

Responsive Environmental Pro tection (July 1996), has been released which presents proposals to update, streamline and consolidate the 80 regu lations that are administered by the Min istry of Environment and Energy. A number of these proposals are directed at the Clean Water regulations and rec ommend reducing the frequency and number of parameters monitored where contaminants are no longer used or pro duced in the plant in question. In addition, it is proposed to harmo nize the monitoring data reporting that is required by federal and provincial au thorities so that one report format will satisfy both. These reforms will likely reduce the operating costs of monitoring and re porting incurred by regulated Ontario plants. However, the monitoring re quirements specified in the Clean Wa ter regulations constitute a very small part of the total compliance costs to regulated companies. Research is un der way to document these compliance costs and the savings that may result from the proposed reforms.

Conclusions

The financial effects and conse

The MISA monitoring regulations

In the aggregate, monitoring costs were under-estimated during pre-program assessments. However,costs were substantially over-estimated for two sec tors: mining and iron and steel. Never theless, statistical tests indicate that es

Q. How can drinking water become contaminated with these parasites? A. Giardia are often found in faeces from

humans, beaver, muskrat, and dogs. Cat tle appear to be the primary source of Cryptosporidium, although they have

Cryptosporidium parvum oocysts.

A. Both parasites produce cysts that are very resistant to harsh environmental conditions. When ingested they germi nate, reproduce, and cause illness. Af ter feeding, the parasites form new cysts.

also occur. These symptoms usually happen within 6 to 16 days of the initial contact and can continue as long as a month.

Drinking water sources become con taminated when faeces containing the parasites are deposited or flushed into water. If water treatment is inadequate, drinking water may contain sufficient numbers of parasites to cause illness. Other sources include direct exposure to faeces of infected humans and animals,

tion or dental hygiene. Q. How are these infections treated? A. Giardia is usually cleared without treatment from healthy people within a month. Anti-parasitic drugs are avail able and are particularly helpful to immunocompromised people in whom the illness could otherwise develop into a persistent state. Cryptosporidium will usually disap pear from healthy people within a month. Anti-diarrhoeal drugs and rehydration therapy may be used if diarrhoea be comes severe. There are no approved drugs to fight the illness although many are now being tested. Q.What extra precautions can immu nocompromised people take? A. Both parasites, but particularly Cryptosporidium, can pose a more seri ous threat to immunocompromised peo ple such as those with AIDS or cancer, or transplant patients receiving immunosuppressive drugs. For these people, the symptoms are more severe and can be life threatening. At present, it is unknown whether immunocompromised individuals are at greater risk to waterborne Giardia and Cryptosporidium than the general pub lic. Nevertheless, immunocompromised

portance of these various routes of ex posure is unknown. Q.Have these parasites been found in Canadian drinking water supplies? A. Low levels of both parasites, espe cially Giardia, were detected in a na tional survey of drinking water con ducted by Health Canada. Only a small fraction of the parasites appeared to be viable. Nevertheless, outbreaks linked

to drinking water have been reported in several provinces. Their spread in swim ming pools has also been reported. Q.How can these waterborne illnesses be prevented? A. Municipal drinking water treatment providing filtration and disinfection can reduce the risk of giardiasis and cryptosporidiosis. Protection of the raw water supply is also beneficial. In the outdoors, water should be boiled for at least one minute before it is

used for drinking, food preparation or dental hygiene. This will destroy Giardia and Cryptosporidium, plus any other disease-causing microorganisms that might be present. Certain types of water filters can remove the parasites. Travellers to countries where the

safety of drinking water is suspect should

kill any parasites that may be present. This practice will also destroy any other microorganisms that might be of concern to these individuals. As bottled water is

not routinely monitored for Giardia and Cryptosporidium, its suitability as an al ternative to boiled tap water is unknown. Q. What should you tell your physi cian?

A.If you are suffering from diarrhoea and suspect that your symptoms may be due to Giardia or Cryptosporidium, visit your physician and mention any exposure to water, food or faeces that may have been contaminated with the parasites. Q. What is Health Canada doing to ensure the safety of our drinking water?

A. A consistent approach to improving drinking water quality is provided by Health Canada's Giddelines for Cana dian Drinking Water Quality (soon to include a guideline for Giardia and Cryptosporidium) which are designed to ensure that Canadians have access to safe

Facts About Corrugated Polyethylene Pipe

Drier cake at higher hydraulic loading rates than two-belt dewatering filters

Corrugated polyethylene pipe, dur ing the past thirty years, has proven itself as a strong, chemically inert, viable pipe for use in applications around the world. In fact, in 1994, the corrugated polyethylene pipe in dustry produced over one billion feet of 4" equivalent pipe. As more and more users and specifiers take no tice and recognize corrugated polyethylene pipe's advantages over concrete, metal and other pipe ma terials, more and more questions

Environmental Problems?

Do you know that 95% of all General Contractors, Architects, Consultants and Engineers have NO Environmental or Pollution Insurance Coverage! Unbelievable, it's true, every day in Canada, environmental remediation work is completed by so-called "professionals" operating without

proper worker training, pollution or environmental insurance coverage. As the person who issued or contracted the work to be done, you could be liable. That's right, you could be sued both corporately and personally in the event of accidents, future contractor employee claims, pollution, contamination and environmental reprecussions resulting from the project being completed improperly. Over 95% of General Contractors, Architects, Engineers and Consultants do NOT have environmental and pollution insurance coverage. They carry only General Liability Insurance and Errors & Ommissions insurance coverage. This insurance does not cover environmental remediation projects or the resulting pollution cleanups and liabilities. Don't risk your future, protect your personal and corporate assets!

formed upon the data. Additionally, this product provides an unparalleled ability to customize all aspects on one's model, from pruning unneeded network weights to analyzing the con tribution of each processing element. It is important to re member that the successful implementation of neural networks depends on the user's understanding of the data and the physi cal properties they represent. When the interpretation prob lems are large and complex, we find that breaking the prob lem down into multiple, small neural networks is often an effective strategy. In our experience, proper creation of train ing and test sets, along with pre-processing the data, consti tutes 90% of the effort in developing a successful neural net work application.

The world's biggest flue gas desulphurisation(FGD)plantand the UK's single largest enviromuental protection project - has been completed at Drax Power Station in Yorkshire, northern England. The FGD plant is a major part of a package of environ mental measures by the electricity generating company. National Power, to meet European Union requirements. The plant's purpose is to remove more than 90% of sul

phur dioxide from the Drax chimney gases which result from burning 11 million tonnes of coal annually. Because of its complexity and scale, the development, which began in early 1990, has been compared with the build ing of the Channel Tunnel. The massive amounts of materi als used in the construction included 30,000 tonnes of stnictural steelwork,200,000 tonnes of concrete, 85 kilometres of

pipework and 400 flue duct sections. The six-year program was carried out without jeopardis ing the daily operations at Drax, the country's largest power station. An extensive part of the project consisted of storage and preparation facilities for limestone and gypsum. Lime stone is used to wash sulphur dioxide from the boiler gases in the FGD absorber units.

Air Pollution Report

Hybrid vehicles could cut Paris air poliution

Byusing both thennal traction

and electric drive, Renault aims to solve the problem of urban pollution caused by cold fossil fuel engines. The growing

rise of air pollution in major French cit ies has made it essential to consider al ternatives to intemal combustion auto

mobiles, the main source of urban air pollution. Having little fossil fuel, but a great deal of electrical power, France has looked to electric vehicles as a possible solution, and a number of them have been tested in French cities. Electric

vehicles have a major drawback: stor ing and gauging their power supply. French automakers have addressed the

problem by developing hybrid technol ogy. Renault, researchers came up with Next, a new hybrid vehicle which re cently completed its first successful drive across Paris.

Mechanical components of standard cars are engineered for maximum per formance levels which most drivers

rarely exploit. Perfonnance levels are still crucial, but require over-sized me chanical structures that unfortunately generate an excess of spent energy. A standard car uses just 40% of its power more than 80% of the time it is on the

road. In addition, while only 25% of a car's power is used in the city, it emits fully 80% ofits polluting exhaust fumes during the first 1,000 m of a 4 km trip, a common distance for urban driving. Cars starting off in the city and heading out oftown leave most of this air pollu tion within city boundaries.

This hybrid successfully drove across Paris. Thanks to the enhanced use of com

puter-aided design (CAD), the scale model stage was skipped and parts were directly machined with the help of dig ital data. Injust twelve months, Renault engineers were able to design a car which is claimed to be a world first in hybrid vehicles.

Next has a 750 cubic cm engine, e.g., 35 kW on the front axle and two, 7 kW electric engines in the rear wheels. An electronic computer,called the supervi sor, is in charge of the complex engine operations, adapting to immediate driv

ing conditions so smoothly that the driver does not even notice the change from one set of engines to the other. By allocating the required power for maximum perfonnance levels to the two axles and alternating the sequential or simultaneous drive, the car can meet

immediate power needs as well as the ever-present requirement to lower fos sil fuel ignition. Depending on the power, the supervisor altemates or adds thermal traction to the electric drive to

lower the amount of gas used. Next burns just 3.4 litres of fuel in compli ance with the latest European require ments, MVEG, which are stricter than former rules, because measurements are now done on the basis of a "cold engine

start" and at variable speeds. Next mns on its electric engine to start and drives at speeds up to 40 kmph. Its thermal engine then takes over, recharg ing the batteries at the same time. Its elec tric engines pitch in with the thermal en gine when the car goes into high speed. Atlow speed the supervisor,an electronic brain, can rev up the thermal engine if it considers that the battery charge is low. During deceleration the electric engines, used as engine brakes, also help recharge the battery. The supervisor also manages other functions at the same time, such as anti-skid and anti-wheel-lock functions,

and steering control. Made mainly of aluminum and car bon fibre. Next is a lightweight vehicle in spite of its 150 kilo batteries. Com pared to a 1.4 litre Renault 19, the hybrid weighs 90 kg less. The car is 4m long and 1.75m wide. Performance levels for Next are at par
