AWWA WQTC59008

As a part of a project funded by the AWWA Research Foundation (AwwaRF) ozoneassisted biological (OAB) filtration was evaluated for its effectiveness on biodegradationof MIB/G. Pilot testing of OAB was performed at the City of Chandler WTP for sixmonths (October 2002-February 2003). This paper presents the pilot study findings of thisresearch project.To address the research goal of biological degradation of MIB/G, an orthogonalexperimental design was developed and tested. The primary objectives of thepilot was first to identify effective filter design for the taste and odor (T&O) (and particulate, total organic carbon (TOC), disinfection byproduct (DBP)precursor) removal:by anthracite to GAC media filters; and,at different filter loading rates (and EBCTs).In orthogonal matrix one variable was altered one at a time from the baseline condition(BL). The objectives of the orthogonal matrix of experiments are to address:optimal ozone dose;influent MIB/Geosmin concentrations;effect of pH; and, effect of pretreatment with and without ozone. Includes 7 references, table, figures.
