Demonstration of a Full-Scale Fluidized Bed Bioreactor for the Treatment of Perchlorate at Low Concentrations in Groundwater
Abstract
West Valley Water District (WVWD), located in Rialto, CA, has commissioned the first-of-its kind full-scale Groundwater Treatment Plant using a fluidized bed biological reactor (FBR) technology to biologically treat water laden with the oxyanions of perchlorate and nitrate. Highly contaminated perchlorate-laden water from the City of Rialto Well 6 and nitrate-laden water from West Valley Water District Well 11 is being treated by the new facility to produce up to 3 million gallons per day (MGD) of quality drinking water for area residents. The plant effluent water is required at all times to meet the requirements per the California Code Regulations Title 22, Div.14, Ch.15 and Ch.17 for drinking water, including meeting the current MCLs in the State of California of 6.0 g/L for perchlorate and 10 mg/L for nitrate-N. The plant was permitted by the Division of Drinking Water in May, 2016 and began full operation in October, 2016.
