First of Its Kind Full-Scale Implementation of a Biological and Chemically Enhanced High-Rate Clarification Solution for the Treatment of Wet Weather Flows at a Municipal Wastewater Treatment Facility

摘要

North Texas Municipal Water District (NTMWD) serves 1.7 million customers by operating onewater treatment plant and four regional wastewater treatment plants including the Wilson CreekRegional Wastewater Treatment Plant (RWWTP). This facility discharges into Lake Lavon,which also serves as the District’s water supply. With continued growth of the service area andthe increased challenge of wet weather flow management, NTMWD evaluated severalalternatives and selected to upgrade and expand the Wilson Creek RWWTP. One keycharacteristic of the adopted alternative is the incorporation of dual-purpose components toprovide both advanced treatment of dry weather flows using a high-rate clarification process(Actiflo?), as well as biological treatment of all wet weather flows by converting the high-ratesystem into a biologically and chemically enhanced mode (BioActiflo?).
