The largest project to date for Zenon Environmental Inc. will be the wastewater treatment of the Gwinnett County F. Wayne Hill Water Resources Center in Georgia. Earlier this year, the company had received a letter of intent to provide its membrane technology to treat 40 million gallons of water per day.
By 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.
Currently, a portion of the treated effluent is being used for landscape irrigation and the remainder discharged directly to the Chattahoochee River, downstream from Lake Lanier, a drinking water source. Eventually, Gwinnett County Plans to discharge the treated effluent directly to Lake Lanier.
Two other Georgia communities also have 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. The project is set for completion by the end of 2003.
The Pooler Wastewater Treatment Facility in Pooler, Ga., currently treats one million gallons per day. After a decision was made to build a new larger plant due to growth in the area, membranes were the technology of choice. The new facility is designed to treat 2.5 million gallons per day. The plant is expected to be completed by September 2004.
