Feasibility Study of PAC (Powdered Activated Carbon) and Pilot Membrane Ultrafiltration Addition for Odor Control

Sweetwater Reservoir, East County San Diego, CA

Abstract:

Sweetwater Reservoir is a conventional filtration plant consisting of chemical treatment, chemical mixing using pumped diffusion, flocculation, dissolved air flotation, and dual-media filters. The Perdue Plant is capable of either treating (pumping) raw water from Sweetwater Reservoir or from the raw water aqueduct pipeline. It is estimated that installation of a PAC silo (to be activated intermittently during the year when taste and odor issues are) would cost about $2.5 million and would have an eighteen-month construction schedule. This estimate is well within the normal operating costs recorded from last year under existing conditions prior to this process addition.
