This powerpoint presentation begins by providing a brief overview of the Zone 7 Water Agency in northern California, and the seasonal taste and odor (T&O) problems it has due to algae in the source
water. The T&O control approach is presented and, compared to a conventional (multi-objective) ozone process, a
T&O-only peroxone process might be much less expensive. The focus of this study was to quantify the potential
reductions in capital and operating costs. The pilot study included
side-by-side operation of a
conventional ozone contactor (10 minute over-under, five
chambers), and a
pipeline peroxone contactor (2.6 minutes) for ozone plus
hydrogen peroxide. The water was spiked with MIB and geosmin, and with bromide as needed, for the
three rounds of spiked testing (June, August, October). Topics covered include: ozone demand; raw water MIB results; settled water MIB results; biodegradable organic matter; raw water ozone vs.
peroxone; and, cost comparison. Includes tables, figures.
