This slide presentation outlines a pilot study for treating taste and odor compounds and the characterization of disinfection byproduct formation that had the objectives of: optimizing peroxide dose based on Electrical-Energy-per-Order (EEO) for reduction of geosmin and 2-MIB; monitoring the effect of AOP on chlorine decay; and, monitor disinfection byproduct (DBP) formation following chlorination. The reasons for optimizing peroxide dose are outlined as follows: H2O2 exerts chlorine demand; removal of H2O2: addition of excess chlorine, and operational concerns (correct dosing); and, optimal H2O2 dose from practical standpoint needs to be as low as possible, effective taste and odor removal, and minimize costs. The second objective involved: testing hypothesis that AOP alters chlorine decay characteristics of a sample through altering NOM; testing initial water, UV photolysis alone, AOP treatment (UV/H2O2) - 1.5, 2.5, 4 mg/L chlorine; monitor free chlorine residual at 15 min, 1 hour, 24 hrs, 48 hrs; and, increasing chlorine consumption may impact DBP production. The third objective of DBP formation following chlorination involved: peroxide quenched with 0.2 mg/L catalase enzyme; NaOCl dosed to result in residual of 1 mg/L after 24 hrs (2.5 mg/L); simulated distribution system (SDS) testing: 15 min, 24 & 48 hrs; and, measure THM and HAA9. Includes 2 references, tables, figures.
