Greater Cincinnati Water Works (GCWW) is currently designing an ultraviolet (UV) disinfection system for the Richard Miller Treatment Plant to enhance public health protection. As part of this process, GCWW is evaluating the intermittent application of an advanced oxidation process (AOP) using UV light and hydrogen peroxide for treating seasonal taste and odor (T&O) events and the continuous application of AOP for treating micro-pollutants. The performance and costs of UV/peroxide were evaluated using a UV simulation tool that predicted day-to-day UV system operation accounting for seasonal trends in water quality and target compound concentrations and the dose monitoring and control strategy used by the UV system. The simulated UV system used medium pressure UV lamps. Contaminant reductions were predicted using a UV dose-based kinetic model that accounted for the reaction of hydroxyl radicals with the target compounds and scavenger species. The kinetic model was based on a theoretical treatment of the advanced oxidation as reported in the literature. The costs of advanced oxidation depended on the seasonal trending in flow, water UVT and scavenger species (alkalinity and TOC) and the optimization of the applied UV and peroxide doses. The costs of intermittent advanced oxidation for seasonal taste and odor events are strongly dependent on the duration of those events and when they occur. Includes 6 references, tables, figures.
