| Chlorine
dioxide (ClO2) is used as both an oxidant and a disinfectant in drinking
water treatment. The required dosages will vary with source water
conditions and the degree of contamination present. For most municipal
and public potable water systems, a chlorine dioxide residual of up
to 2 ppm is sufficient to provide adequate disinfection. Residual
disinfectant and disinfection byproducts must be monitored as required
by the National Primary Drinking Water Regulations (40 CFR Part 141)
and state drinking water standards. |
