Document Description
Even though the potential energy and capital cost savings are significant, primary effluent filtration as an intermediary wastewater treatment step (IWTS) has not yet been implemented at Wastewater Treatment Plants (WWTPs). In March 2011, Kennedy/Jenks conducted a Pilot Study at the Dry Creek WWTP in Roseville, CA (Roseville Pilot Study) for four weeks to preliminarily assess the technical feasibility of primary effluent filtration as IWTS. Twenty-nine tests were performed using two types of filters. Recent commercialization efforts led by the Project Team such as the Roseville Pilot Study and this demonstration proposal are in response to the apparent market need for this emerging technology and suitability of the newer wastewater filtratio technologies for primary effluent filtration. The Rosevillde Pilot Study results have indicated the feasibility of primary effluent filtration as IWTS to achieve significant energy savings at WWTPs. The proposed demonstration project is the next step to commercialize this emerging technolgoy to overcome the technological barriers. The demonstration will occur at the Linda County Water District WWTP in Marsville, CA.
