AWWA WQTC69229

The taste and odor compounds (T&O) 2-methyl isoborneol (MIB) and geosmin are of concern to water authorities world-wide. Through an AWWARF research study grant, a pilot unit based on the coupling of membranes and powdered activated carbon (PAC) was set up in the drinking water treatment plant of T.W. Moses in Indianapolis, Indiana. This plant presents the most problematic issues related to taste and odor, since the exclusive resource of this plant has encountered regular algal blooms during recent years. On one hand, physical-chemical parameters (MIB and Geosmin quantifications, TOC/DOC, turbidity) enabled us to characterize the taste and odor removal; and, on the other hand, a continuous data acquisition was set up to get hydraulic parameters. Two main periods of pilot experiments were carried out in a row from July to November 2007. Includes 6 references, tables, figures.
