The Metropolitan Wastewater Management Commission (MWMC) is upgrading the Eugene/Springfield Oregon Water Pollution Control Facility (WPCF) by adding filtration facilities to meet future regulatory requirements for effluent discharge and Class A recycled water criteria. Because effluent filtration technology has advanced significantly in the last ten years, the first phase of the project entailed a pilot filtration study to select the most beneficial filtration technology for the WPCF. The results obtained from the pilot study are being used for the design of filtration facilities with a total treatment capacity of 14 million gallons per day (MGD). Pilot testing commenced in July 2008 and lasted approximately 20 weeks. The pilot study involved parallel testing of three different types of wastewater filtration technologies using the same influent to the filters. The technologies tested were: (1) Cloth Disk Filtration, (2) Compressible Medium Filtration, and (3) Granular Medium Filtration.

Keywords: Secondary effluent filtration; cloth disk filter; compressible medium filter; fuzzy filter; granular filtration; primary effluent filtration
