Full Description

In the past decade, utility managers havebeen resolved to isolating contaminated aquifersand developing alternative water sources. However,with drought conditions developingthroughout the western United States, waterproviders need to reconsider using any availablewater sources as potential potable water.This study was undertaken to demonstratethe efficacy of biological fluidized bed reactor(FBR) technology in treating perchlorate-ladengroundwater. In this process, microbes treat theperchlorate and convert it into an innocuousform that allows the water, following furtherdownstream treatment in a traditional surfacewater treatment facility, to be used as a potablewater source.Results from a large pilot-scale biologicalFBR showed that the overall treatment plantwas effective in removing perchlorate and producingpotable water that met all of California'sTitle 22 drinking water regulations. Studyfindings also provided critical design data thatcan be applied to a potential full-scale treatmentplant capable of safely and cost-effectivelytreating a water source previouslyunavailable. Includes 31 references, tables, figures.
