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.
