Thickening and Dewatering Polymer Services

The County is seeking polymer vendors to provide thickening and dewatering polymers for the Chambers Creek Wastewater Treatment Plant (WWTP), located at 10311 Chambers Creek Road West, University Place, WA 98467. The Chambers Creek WWTP treats an average raw influent flow of approximately 18 million gallons per day (MGD). Primary Sludge and Waste Activated Sludge (WAS) are currently co-thickened on rotary drum thickeners using a dry polymer system. Digested sludge is dewatered by centrifuges using an emulsion polymer. The purpose of this RFP is to receive proposals from vendors that would like to supply Pierce County’s thickening and dewatering polymer. Vendors must prove the effectiveness of their proposed polymers by conducting bench testing for both thickening and dewatering polymer and full-scale testing for just the dewatering polymer.
