AWWA ACE65470

This powerpoint presentation begins by providing background information on a chromium problem at a Glendale, California, Water Treatment Plant (GWTP). A Four-Phase Program Initiated by Glendale included:Phase IBench Study, AwwaRF-sponsored study to screen technologiesfor Cr(VI) removal and evaluate redox chemistry(Brandhuber et al., 2005); Phase IIPilot Study, US Environmental Protection Agency (USEPA)-sponsored study of 6technologies at pilot-scale (McGuireet al., 2006; Qin et al, 2005); Phase IIIDemonstration Study, USEPA- and AwwaRF-sponsoredBridge Project, Additionalrequests for demo. funding; and,Phase IVFull-Scale treatment implementation. Treatment technology evaluation includes:Bridge Project - initial part of thePhase III Demonstration Study; purposes of the Bridge Project includingtest additional WBA resins,test constant pH conditions, andinvestigate characteristics ofWBA residuals to identifymechanisms of Cr(VI) removal. Treatment technology evaluation and residuals analysis are provided.
