As a part of a project funded by the AWWA Research Foundation (AwwaRF) ozone
assisted biological (OAB) filtration was evaluated for its effectiveness on biodegradation
of MIB/G. Pilot testing of OAB was performed at the City of Chandler WTP for six
months (October 2002-February 2003). This paper presents the pilot study findings of this
research project.
To address the research goal of biological degradation of MIB/G, an orthogonal
experimental design was developed and tested. The primary objectives of the
pilot 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.
