industrial news US water treatment projects use ZeeWeed technology Zenon Environmental’s ZeeWeed® membrane technology is being used in four major projects in the USA. The company, which is based in Oakville, Ontario, Canada, claims that its largest project to date for wastewater treatment will involve expanding the Gwinnett County F. Wayne Hill Water Resources Center in Georgia. Zenon originally announced during January 2003 that it had received a letter of intent to provide its membrane technology to treat over 150 million litres of wastewater per day. By the end of 2005, Gwinnett County is expected to have the largest tertiary treatment facility in the US that is based on ZeeWeed membranes. The existing plant is a water reclamation facility that currently treats 75 million litres of wastewater per day, and is based on a traditional approach to wastewater treatment. Adam Minchey, directo of engineering and construction for Gwinnett County, says that although the existing plant is meeting all current standards, the decision to adopt ZeeWeed technology was made because of its performance and cost effectiveness, in addition to the fact that membranes provide potential benefits for future improvements to processes. Two other Georgia communities have also made the decision to use membranes for wastewater treatment. The City of Woodstock Rubes Creek Water Reclamation Facility has been incurring significant fines for not meeting existing permit requirements for the quality of effluent that is being discharged into Rubes Creek. It currently uses a nonmembrane system to treat 1.9 million litres of wastewater per day, but the city council decided to retrofit and expand the plant to one that uses a ZeeWeed membrane system which will treat 5.7 million litres per day. The project is set for completion by the end of 2003. The Pooler Wastewater Treatment Facility in Pooler, also in Georgia, currently treats about 3.8 million litres per day. A decision was made to build a new larger plant, because of growth in the area. The new facility, which use membranes, will treat around 9.5 million litres of
wastewater per day. The plant is expected to be complete by September 2004. In other news, the City of Redlands in California has affirmed its commitment to water reclamation and environmental sustainability with the purchase of a ZeeWeed membrane bioreactor (MBR). California is one US state that has been experiencing growing water shortages. The City of Redlands is optimizing the use of its limited drinking water supply by re-using
wastewater for non-potable purposes. According to Douglas Headrick, chief of Water Resources for the city, the efficient use of recycled water will free up around 7600 million litres of limited water resources, making it available for use as drinking water. The recycled water produced by Zenon’s MBR will be sold to industrial, commercial and agricultural customers.
