ADVANCED WASTEWATER TREATMENT USING STATE-OF-THE-ART MEMBRANE PROCESSES AT GWINNETT COUNTY, GEORGIA
Abstract:Gwinnett County, GA is located on the north side of Atlanta and is one of the fastest growing counties in the nation. The County's new 20 mgd reclamation facility, named the F. Wayne Hill Water Resources Center (FWHWRC), was commissioned in December 2000 and treats municipal wastewater to near-potable water quality. Biological processes at the plant are designed for complete nitrification, partial denitrification, and phosphorus reduction. Tertiary treatment processes include “high-pH” lime, granular activated carbon (GAC), and ozone before and after GAC. The high-pH lime treatment process includes solids contact reactor-clarifiers, two-stage recarbonation with clarification, and granular media filters.
