OAKVILLE, ON, July 14 /PRNewswire-FirstCall/ -- Zenon Environmental Inc. largest project to date for wastewater treatment will be the expansion of the Gwinnett County F. Wayne Hill Water Resources Center in Georgia. The company originally announced in January 2003 that it had received a letter of intent to provide its membrane technology to treat 40 million gallons of wastewater per day.

By the end of 2005, Gwinnett County is expected to have the largest ZeeWeed based tertiary treatment facility in the country. The existing wastewater treatment plant is a water reclamation facility that currently treats 20 million gallons of wastewater per day, and is based on a traditional approach to wastewater treatment.

According to Adam Minchey, Director, Engineering and Construction for Gwinnett County, although the plant is meeting all current standards, the choice was made to adopt Zenon's ZeeWeed membrane technology because of its performance and cost effectiveness, in addition to the fact that membranes provide potential benefits for future improvements to processes. "We would like to enhance the quality of life for our residents as well as improve our surrounding environment," said Mr. Minchey, "and membranes will allow us to achieve both."

Currently, a portion of the treated effluent is being used for landscape irrigation and the remainder discharged directly to the Chattahoochee River, downstream of Lake Lanier, a drinking water source. Eventually, Gwinnett County plans to discharge the treated effluent directly to Lake Lanier.

"Using ZeeWeed membranes will produce a high level of water quality that will be able to meet increasingly stricter standards," continued Mr. Minchey. "This technology has been proven and is also being used in other parts of the world to augment additional drinking water supplies particularly in water short regions."

Two other Georgia communities have also made the decision to go to membranes for wastewater treatment. The City of Woodstock Rubes Creek Water Reclamation Facility has been incurring significant fines for its inability to meet existing permit requirements for the quality of effluent being discharged into Rubes Creek. One of the factors stems from overflow situations that have resulted from increasing growth in the community.

City Council decided to retrofit and expand the plant, which is currently using a non-membrane system that treats 0.5 million gallons of wastewater per day, to a ZeeWeed membrane system that will treat 1.5 million gallons per day, with the possibility of future expansion. Zenon's technology makes it easy to retrofit the plant by using the existing tanks for the plant expansion, without disturbing ongoing plant operations. The project is set for completion by the end of 2003.

One of the key reasons for this decision was the opportunity to reuse the treated effluent. Currently, the plant discharges into the Hardin Canal, adjacent to the site. However, there are future plans to reuse the water for irrigation. The plant is expected to be complete by September 2004.

Zenon is a world leader in providing advanced membrane products and services for water purification, wastewater treatment and water reuse to municipalities and industries worldwide. Additional information is available at the Company's web site www.zenon.com.

Franklin, NJ -- The Spiralift SR streamlines receiving and processing of septage. This self-contained system receives, screens and conditions septage in a fully enclosed, pre-engineered system. The system is supplied with complete controls to automate, monitor and validate hauler usage.

The Spiralift SR is available in several models to handle up to 750 gpm of raw septage with single or double stages of separation. Features of the Spiralift include a fine screen, shaftless screw system for conveying the screenings to a convenient elevation for discharge, wash sprays, ultrasonic level sensor, quick disconnect inlet flange connection and a complete control system and an automatic inlet valve to regulate the flow. The system is housed in a stainless steel tank enclosure.

The Spiralift SR is supplied complete with a control system to monitor and control system operation. An optional billing system with keypad or credit card automatically validates, monitors and records individual septage hauler transactions.

Membrane bioreactor (MBR) technology offers an exciting future for wastewater treatment. A technology that has been in commercial use for little over 10 years is finally beginning to show some of the initial market promise and is attracting the attention of municipal and industrial facilities in search of effective wastewater recycling processes. This technology’s ability to comply with strict effluent requirements, to be easily retrofitted, and to occupy far less space than traditional systems emphasize its growing importance to such facilities.

Customer uptake of membrane bioreactors has been slow. Many potential operators were deterred by perceived drawbacks of this technology such as its complex and small-scale nature, high costs and operator skill requirements, among others.

As Frost & Sullivan ( http://www.frost.com ) Industry Analyst Matthew Barker says: "Perhaps the biggest challenge to companies active in the market is to persuade decision makers of the capabilities of membrane bioreactors and the benefits they will undoubtedly bring to the customer."

Companies looking to succeed in this market must strive to understand the needs of each industrial end user, the workings of the particular industrial sector, as well as the demands that the end users’ effluents will place on the equipment. Furthermore, building a close working relationship with the customer by offering guarantees on membrane lifespans or service and maintenance contracts is emerging as a key competitive factor.

The possible applications of this technology are numerous, and can be found in municipal facilities as well as industrial facilities that are interested in an effective recycling technology. Recent industrial plants include dairy plants, food processing plants, pharmaceutical applications and marine based plants for both offshore rig and sea craft applications.

The European municipal and industrial wastewater markets are slated to be important sources of demand for membrane bioreactors. Strict European regulations such as the Urban Wastewater Treatment Directive (UWWT), which has a 2005 deadline, are expected to spur continued investment in wastewater treatment works by small and mid-sized municipalities. Once municipalities have met the deadline, further growth will arise mainly from the replacement and upgrading of old equipment, and is also likely to be small compared to growth in the industrial wastewater market.

"Membrane bioreactors will achieve good growth in demand from the industrial wastewater sector in coming years. The challenges of removing contamination from wastewater with maximum reliability and efficiency by using wastewater treatment processes, plants and systems are growing, offering good opportunities to companies with new and advanced technologies," states Mr. Barker.

Among other applications, landfill leachate is especially promising, with reference plants in Germany, France and Holland leading the way. Anticipated regulations along with emerging and existing environmental policies is spurring the maritime industry to strongly consider MBR technology as a way of achieving zero untreated liquid discharge.

Although currently at the development to growth stage of its lifecycle, the European membrane bioreactor market affords considerable opportunities to existing as well as new participants. Growing acceptance of MBRs, escalating interest in water re-use and recycling technology and increased demand for advanced wastewater treatment solutions and systems assure them of a bright future.
