Pilot Plant Study on the Use of Chlorine Dioxide and Granular Activated Carbon

摘要

Chlorine dioxide is shown to be an effective disinfectant and its use allowed a 30-40% reduction in trihalomethane precursors in this pilot plant study in Evansville, Ind. Granular activated carbon removed up to 80% of the remaining precursors at the beginning of a test run when the influent concentration was high (120 micrograms/l) with no removals at exhaustion after 30 days of use. Performance curves for total organic carbon removal were constructed for virgin and regenerated granular activated carbon; both showed an initial average removal of about 75%, and, after total organic carbon-exhaustion of about 60 days, the rate dropped to 23%.
