The provision of abundant safe and reliable drinking water requires a multidisciplinary combination of dedicated scientists, engineers, chemists, opera tors, contractors and suppliers. The low bid ethos is the most inappropriate way that I know of to ensure the reliability and safety of our water and wastewater systems. Walkerton was the first wakeup call of the new millennium. We must ensure that it is the only such tragedy of this century.

The New Generation N-Pumps.

They'll run efficiently day after day after day...

N-Pumps win Canada's Energy Efficiency Awards 2000. The energy-using equipment award for sustained efficiency in raw sewage. Chances are, that every day you run your pumping operation, your costs are creeping up and up: maintenance, servicing, the cost of replacement. So the New Generation N-Pumps could bring a brighter start to your day. The N-impeller is designed to prevent clogging and maintain higher pumping efficiency over longer periods.

The N-technique, patented by ITT Flygt, features a self-cleaning impeller that, together with an integrated relief groove in the pump housing, ensures sustained high hydraulic efficiency and clog resistance.

The Spin-outâ&#x201E;˘ seal protection system prevents particles from damaging the seals. New, improved cooling means the motors operate more efficiently, and at lower temperatures. And the new Plug-inâ&#x201E;˘ seal system means that if you do have to replace a seal, it'll take just a few minutes. Have a nice day. Day after day. Call us for more information, or visit us at

The TOVEKO CX continuou.s filter is a novel method of

suspended solids removal using sand filtration. It may be used with or without chemical precipitation according to the application, and is well suited for tertiary filtration in both sewage and industrial wastewater treatment applications. The TOVEKO CX sand filter continuously cleans itself whilst in .service, and the sand bed is, therefore, continuously moving. The compact nature of its modular construction provides significant advantages to the user in both space requirements and investment cost.

It is delivered to site largely pre-assembled and tested, thereby minimizing set-up costs. ,Wash water

The success and broad acceptance of the STEP SCREEN system is due to its function,easy-to-understand operation, simple cleaning, (self-cleaning effect is due to the counter current principle), easy servicing, ability to handle very large screenings volumes and operating reliability. The motor linkage drive has been developed from the proven and patented link system. To the benefit of our customers, we did intentionally avoid difficult-to-maintain chain drives, with the linkage type we are able to master the occuring bending moments on the laminae,in particular with high water levels.

WEFTEC Review

WEFTEC 2000 blended education, science, networking and entertainment WEF's Anaheim ceremonies rivalled Academy Awards

Perhapsinfluenced by its close proximity to Holly

wood, the opening ceremonies of the WEFTEC

2000 conference and exhibition took on the look

of the Academy Awards, complete with upbeat music, a backlit stage, revolving Water Environment Fed eration(WEF)logos projected onto the ballroom walls, and entertaining speakers. Keynote speaker, Dr. Sylvia Earle, of Deep Ocean Ex ploration and Research Marine Operations,gave a first hand account of how important marine life is to the whole eco system. She showed photo highlights taken from more than 50 expeditions and 6,000 hours underwater diving. Emphasizing that overfishing is the major stress factor on marine ecosystems, she gave some startling statistics. In just over four decades, the worldwide tuna population has declined to 20% of what it was. Another bioindicator is

the horseshoe crab, which has survived uncounted global calamities over the past 400 million years. Yet in just 40 years, its population has shown a marked decline due to the

Keynote speaker. Dr. Sylvia Earle. The Water Environment Association of Ontario was well

represented this year, with members picking up three WEF awards. Geoff Scott, a past president of WEF and WEAO, was made an honorary member. The Regional Municipality of York received the Public Education Award. The region launched its Water for Tomorrow School Education Program in order to improve

the efficiency of water use. An important element of the program was public outreach and education programing. These programs were intended to educate and change the water-use attitudes of York Region residents. Booklet, in formation leaflets, newspaper advertising and teacher manu als were circulated to residents and schools.

Dr. Earle urged people to go diving and see for themselves the wonder and diversity of the marine ecosystem. Only then, she said, will they not just view marine life as food. President Al Goodman demonstrated AquaVenturer, a WEF sponsored interactive CD-ROM program to some 2,000 delegates. This CD-ROM tells the story of water, its treatment and use throughout history. Mr. Goodman also explained WEF's role in the 13 part documentary series. Water, a drop of life which was broadcast this fall. The series, presented by Cormecticut Public Television, travels around the globe to examine the social, economic, cultural, strategic and agricultural aspects of drinking water.

David Bagley and Toby Brodkorb received the prestig ious Harrison Prescott Eddy Medal. The two water quality professionals were honoured for their paper: Modeling Microbial Kinetics in an Anaerobic Sequencing Batch Reac tor - Model Development and Experimental Validation, which was published in Water Environment Research. Their paper presents experimental results and modeling for a relatively new anaerobic treatment process, that has the potential to catalyze more implementation by practition ers of anaerobic batch reactor treatment. The Eddy Medal is awarded for research that makes a vital contribution to

existing knowledge of the fundamental principles or proc ess of wastewater treatment, as comprehensively described and published in a WEF periodical. David Bagley is an associate professor of civil engineer ing at the University ofToronto. Toby Brodkorb is a project engineer with CH2M Hill (Toronto). During its annual meeting held during the conference, the WEF Board of Directors voted, after considerable de

bate, to go with a two-city rotation beginning in 2010. Chi cago and New Orleans will be the only two host cities after that date. The Board also approved the 2001 budget of $18,552,600(US)prepared by WEF Treasurer Prad Khare, from British Columbia.

What is Pressure Pulse Technology? About 15 yeai's ago. Dr. Tim Spanos at the University of Alberta finished the initial development of a rigorous theory of porous media mechanics. Previous simplifications and assumptions were examined, found wanting, and cor rected, resulting in a theory that is more thermodynamically sound than either Darcy theory for non-dynamic flow, or Biot-Gassmann theory for wave propa gation. For example, Spanos found that porosity in porous media plays a funda mental role; to be rigorous, it must be Continued overleaf

have clearly demonstrated the importance of reliable disinfection/chlorination

equipment to maintain a safe drinking water source. The use of sodium hypochlorite as a disinfectant for drinking water, with properly designed equip ment, is a safe, reliable and simple method.

Sodium hypochlorite addition to water

Sodium hypochlorite is commonly added to water by positive displacement, diaphragm-type chemical metering pumps. These pumps provide a high degree of dosing accuracy and reliabil ity, and are available with chemically compatible wetted parts materials such as PVC, acrylic, VitonÂŽ, PVDF, and TeflonÂŽ. Due to the nature ofsodium hy pochlorite, it is normally recommended to use an auto degassing pump head to eliminate the problem of air locking. Safety precautions to be observed when working with sodium hypochlo rite include providing adequate ventila tion and an eye washer/shower station, containment for spill collection, and double wall pipe or tubing over high traffic areas. Also, pump backpressure valves should be installed at the injec tion location to prevent siphoning and to improve pump accuracy.

Sodium hypochlorite addition based on flow and measured chlorine residual. Chlorine residual measurement and control Once chlorine is introduced to wa

ter, a portion will react with organic/oxidizable matter, a portion will form com bined chlorine (chloramines), and the remainder will be free chlorine. Subse

considerations and high capital investment. On the other hand, sodium hypochlorite is slightly more expensive, but has a low capital investment cost and is safer to handle. An alternative to chlorination is chlorine dioxide, which

provides more powerful and rapid disinfection, and prevents the formation of by-products such as chloramines and THMs. Chlorine dioxide, which is widely used through Europe, is however a more expensive means of disinfection than chlo rine due to the capital investment cost of a generator and higher chemical cost. Ozone and ultraviolet are two other effective alternative methods of disinfection. However,they require high capital investment and are not able to provide a residual in the distribution system. Conclusions

Chlorine has played a crucial role in protecting our drink ing water supply from waterborne diseases throughout the world for nearly a century. As a disinfection method, chlo rine has proven itself to be effective against a variety of pathogens such as bacteria E. Coli, Salmonella (typhoid). Vibrio (cholera), and virus hepatitis A. There exist simple and proven methods of addition, meas urement and control for chlorination readily available to provide a safe reliable water source. Liquid sodium hy pochlorite and metering and control equipment are very costeffective. In addition, operation and maintenance of the equipment require minimal training skills. The main benefit of providing a properly engineered chlorine-based disinfection system, which is the elimina tion of waterborne diseases, far outweighs the potential health risks associated with disinfection by-products such

as chloramines and THMs. Especially since these by-prod ucts can be considerably reduced or eliminated by design ing a proper water treatment system,that takes into account raw water quality, in synergy with chlorine disinfection. For more information, circle reply card No. 123

(Ontario Superior Court of Justice, May 2000), highlights this shift. The facts of the case are simple. In September 1990,a leak in the line running between an underground storage tank and the gasoline pumps caused a fuel spill at a gas station. The leak was repaired, and the contaminated soil replaced. In Au gust 1991, subsurface contamination was discovered on land abutting the gas station. The source of the contamina

Unusual recycled water process developed for sewage system In Nunavut

The owner of a bed and breakfast in northern Canada, Jens Steenberg, is using a recycling de

vice that could transform water use in the Arctic.

He has not emptied the sewage tank servicing his business for 18 months, thanks to what he calls a biofilter.

This is a two metre wide cylindrical tank and a covered vat, plus a tangle of pipes, tubes and gauges. The device works like an in-house septic tank, using naturally occumng bacteria to strain the solids out of wastewater. Water left behind is filtered further, disinfected with

biofilters. Mike Richards, the head of that community's housing association, said the hamlet is optimistic about the $80,000 project. He expects the technology to spread throughout the community if the cost savings end up being significant. He said: "They're pretty diligent about trying to save money here. If we can cut down our water delivery by a third or a half, that's pretty substantial." The biofilter was designed as part of an integrated sys tem known as the Healthy House System. "The Canada Mortgage and Housing Corporation ran a Healthy House competition in the 1990s. 'The specification was that the house needed no municipal services," said Mr. Paloheimo. "Our system won it." The biofilter is still at the pre-commercialization stage, but interest is growing across Canada and particularly in China. Systems have been installed in Toronto, North Van couver, another project in Yellowknife, as well as Iqaluit and Cape Dorset. Source: Nunatsiaq News online.

Corrective action must begin imme diately and continue until the adverse water quality is no longer detected. This will normally be accomplished by in creasing the chlorine dosage to at least 1.0 mg/L and continue until a free chlo rine residual of 0.2mg/L is achieved at all points of the affected parts of the dis tribution system and two consecutive sets ofsamples and analysis show no ad verse water quality, or as otherwise di rected by the Medical Officer of Health.

Quarterly reports de scribing the water system,its operation, analyses made, and measures taken to comply with the regulation are required. Municipalities will be required to do this this year as the regulation went into effect August 26, 2000. Any conviction for an offence under the Ontario Water Resources Act that

Drinking water supplies generally originate from either surface water or groundwater;therefore,a defined path way exists from the raw water source to the consumer through which waterborne disease can be transmitted.

Pathogen survival depends on a num ber offactors like temperature and time. Some pathogens will survive for only a short time in water. Others may survive for months; for example, if manure is Environmental Science & Engineering, January 2001

Infrastructure & Drinking Water not spread properly, pathogens may be present, wash off fields into the surface water, and impact a water supply down stream.

Bacteria, protozoa, and viruses are the microbiological contaminants of concern and must be subject to rigorous monitoring and analysis. The new regu lations make this mandatory,regardless of whether the system has had a long history of no microbial or toxic contami nant problems. Testing is mandatory and must be followed rigorously. All staff involved need to be trained and fully understand both the importance of their monitoring and testing activities and the necessity of advising the authorities immediately regarding any adverse conditions. These staff are the vanguard of the water op erations, and they must know their du ties thoroughly. Compulsory licensing is now required, as is mandatory train ing of a total of 76 hours per year. The responsibility of the water system's staff in safeguarding public health is para mount.

Sources of Pollution

It is important that a supplier of water knows its water source and does

everything possible to protect it. This includes more than just monitoring and testing. The supplier must understand any factors that could possibly have an impact and have emergency procedures in place to react to potential problems. Potential areas of concern include sew

age and storm sewer discharges and nonpoint source (i.e. runofffrom feed lots). As these factors may have temporal or seasonal effects, sampling for impacts must be vigilantly carried out year-round and be increased during periods of wet

PCB Focus

Accumulation of PCBs and other POPs In Canada's Arctic

The long-distance transport of Persistent Organic Pollutants

(POPs) such as PCBs into Canada's Arctic has caused health and environmental risks to the

indigenous people of that area. A study of sea-food traditionally eaten by First Nations' people of the Arctic has shown that they have markedly high levels of PCBs in their diet. As PCBs have never

been manufactured in the region, these high concentrations cannot be attributed to local sources. Rather,they have been transported from other regions. The excessively high level ofPOPs in Arctic environments has led to research

into the pathways by which the POPs reach the area. Due to the Arctic's cold

climate and geographic characteristics, it is a sink for contaminants such as PCBs,

originating from around the world. The Arctic air mass efficiently trans ports particle-size contaminants across the Pole,from industrialized regions of Eurasia. Semi-volatile compounds are carried to the Arctic by cycles ofevapo ration, transport, and condensation. Rain, snow,ice and dry deposition cap ture the airborne contaminants and pol lute the surfaces on which they settle. Rivers process contaminants by sedi mentation and resuspension of particles. Lakes, estuaries, and deltas act as sedi

ment traps and sinks for contaminants. Melting ice releases its contaminants

into the biologically dynamic shelf seas

The excessively high level of POPs In Arctic environments has led to research Into the pathways by which the POPs reach the area. While the effects of POPs, such as

PCBs in the Arctic are not yet fully com prehended, it is clear that they accumu late in fatty tissues, as they do not break down easily. At the top of the food chain, human beings are susceptible to the highest concentration of these con taminants.

Ecosystem Restoration The main objective of this program was to conduct a short duration,but high

production capacity, sediment dredging and processing operation that would allow for sufficient data to be collected.

Associated Engineering was respon sible for evaluation ofsediment dewater-

ing technologies, completion of a con tractor prequalification process, tender documents,contract administration,and

report preparation. Technical feasibil ity of a potential full-scale dredging pro gram was assessed,considering method, feasibility and impacts of dredging, dredging rates, environmental impacts, process and implications for on-site sediment dewatering, and off-site sol ids disposal constraints Trimax Residuals Management Inc., retained as the project contractor, was responsible for the dredging, sediment dewatering, and water treatment opera

A silt curtain encircling the dredging site proved successful in preventing sediment migration down the lake. Lake water samples were collected on a daily basis and analyzed for turbidity, TSS, pH,conductivity and dissolved oxygen in order to determine dredging impacts. Dewatered sediment samples were tested for metals and hydrocarbons. To confirm that residual polymer (used to enhance the solids capture of the centri fuges)in the effluent would not be toxic to aquatic life, bioassay toxicity tests

ITT Flygt wins energy efficiency awards

The2000 Natural Resources Canada,Energy Ef i

ciency award was presented to ITT Flygt for N-Pumps Sustained Efficiency in Raw Sewage. Categories included: equipment and technology, building, housing, media and student competitions. ITT Flygt's N-pumps won the equipment category. The N-pump series features a radical new hydraulic end design which ensures efficient, clog-resistant, and troublefree pumping over extended periods. The result is improved operational economy due to less downtime,dramatically re ducing the total life cost of the installation. Its unique, self-cleaning design produced an award-win ning performance: •75% to 80% hydraulic efficiency at Best Efficiency Point, even in fluids with a high solids and fibrous content. • Clog-resistant operation. • At least 15% to 20% reduction in power consumption, in field testing with over 100,000 hours in operation. Commenting on the award, Michel Bakhos,P.Eng., Gen eral Manager,ITT Flygt, Canada, said: "Engineers, opera tors and manufacturers have been expending considerable resources in their efforts to reduce energy consumption in

water mix Under normal conditions, oil and water don't mix. But "near-critical" water -

very hot but still liquid water at tempera

tures of 250° to 300°C and pressures of 1,000 psi - can be a good solvent for both salts and non-polar organic com pounds, including oils. This makes or dinary water an ideal reaction solvent for certain chemical processes. Researchers at the Georgia Institute ofTechnology are studying a wide range of chemical processes in search of ap plications in which the special proper ties of this "near-critical water" might provide both economic and environmen tal advantages. Their work could lead to replacement of traditional organic solvents in certain specialty chemical processes.

A full complement of Ro-Flo rotary sliding vane type gas compressors is available to suit your specific digester gas handling needs. Offered in single or two-stage configurations, these compressors are uniquely designed to provide extended operating life while handling a variety of dirty, corrosive gas mixtures. For

convenience, the Ro-Flo compressor can be factory equipped with a full complement of accessories to provide you with a completely self-contained package.

Details of the work were presented at the 1999 American Chemical Society national meeting in New Orleans. Certain types of chemical reactions operate well in near-critical water, and would be top candidates for the new process, he said. Use of water as a sol vent could also be attractive for proc

esses in which all traces of hazardous solvents must be removed - such as in

pharmaceutical manufacturing. "Water is about as ideal a solvent as

you could imagine," Eckert noted. "Not only is it benign, but the public percep tion is that it is benign." Both the be

nign nature of water and its potential as a powerful solvent depend on its unique system of hydrogen bonding. As water is heated, its normally strong hydrogen bonds weaken, allowing dissociation that forms acidic hydronium ions and basic hydroxide ions. At the near-criti cal stage, the amount of dissociation is three times what it would be at normal

temperatures and pressures. "Simply from the dissociation of water into acidic and basic ions, a much larger amount of acid and base is present in near-critical water," Eckert explained. "We can use these to run acid-catalyzed and base-catalyzed reactions without the addition of mineral acid."

Near-critical water has properties similar to those of polar organic solvents like ethyl alcohol or acetone. Its dielec tric constant drops from 80 to 20, and its density drops from one gram per cu bic centimeter to 7/10 gram per cubic centimeter.

High-tech wastewater system for ice cream firm

Chapman's Ice Cream in Markdale, Ontario, is a

family business. Since its beginnings as a small creamery in 1971,it has grown to a multi-million dollar business producing ice cream products un

der its own brand name and others, such as President's Choice.

Ice cream production uses a lot of water, most of it in cleaning, which is carried out on a regular basis in the pro duction cycle. The waste stream consists mostly of water, milk solids, sugars,flavourings and cleaning chemicals. Last year the owner decided it was time for the company to be treating its own wastewater, rather than sending it to the municipal system. He contracted the design and engineer ing of the new wastewater treatment facility to Elmira Pump Company, and gave owner Jim Germann, instructions to build a first rate system. Jim decided to use Endress -i-Hauser instruments for all measuring points in the new plant. From the main plant the wastewater is held in a collec tion pit before being piped to the new facility. Here it goes into a 16 foot, 12,000 gallon surge tank which acts as a hold ing system to even out the flow. The level in the surge tank is measured by Prosonic T ultrasonic level transmitters. In the next stage, the wastewater is pumped by variable speed drives to a neutralization tank where coagulant and polymer are injected to start the precipitation process. Caus tic soda and sulphuric acid are added to neutralize the wastewater. This 12foot tank contains an aggressive mixer. E+H analysis instruments measure turbidity and pH and control the amount of chemical to be added. Level is again measured by Prosonic T. Levels in the coagulant and poly mer tanks are measured with Multicap T capacitance probes. Wastewater is then pumped to the DAP (dissolved air flotation clarifier) where air is injected under high pressure causing bubbles to be trapped in the flocculant which then

rises to the surface. A scraper at the top of the DAE re moves the foamy solids which are collected in a holding tank. The resulting effluent is pumped to a holding tank where pH and turbidity are again measured before release to the municipal sanitary sewer. If the effluent is not in compliance, an alarm causes the system to reject the final discharge and the effluent is recycled through the process. All measurements are relayed to a PEG and control panel in the wastewater facility.

Arsenite-containing effluent is generally oxidized prior to precipitation to ensure that the arsenate predominates. Wastewater from the processing of arsenic bearing ores may contain varying amounts of arsenic (III) and(V)oxyanions, arsenites and arsenate. The pres ence of such metal ions as copper, lead, nickel, and zinc limit the solubility of arsenic because of the formation of spar ingly soluble metal arsenates. The stability and solubility of these arsenates depends on the ratio of iron to arsenic. The larger the ratio, the more insoluble and stable the precipitate.
