Description
Summary:The recent emphasis by federal and state regulators on groundwater protection has brought wastewater under greater scrutiny. Environmental agencies now look with increasing disfavor upon the use of exfiltration for disposal. Under this scrutiny, true zero discharge provides the ultimate alternative for power plant compliance. However, few have achieved it, particularly in wet areas. One plant that has accomplished true zero discharge in such a climate is the Orlando Utilities Commission's Stanton Energy Center. All treatment systems used at Stanton are of proven design. Pretreatment of well water includes aeration, lime softening in a sludge recirculation solids contact basin, and dual media filtration. A computer program simulates overall plant water balance. It predicts water quality based on the occurrence of events, including such variables as rainfall, plant load, or brine concentrator treatment rate. The program is able to predict trends over several weeks or months for a combination of events.
