UV Oxidation for Disinfection and Taste and Odor Treatment



Deteriorating drinking water quality, including the presence of algae-bloom-derived taste and odor-causing compounds and algal toxins, continues to be a major concern for municipal drinking water suppliers. Off-tastes and odors can significantly erode public confidence in the safety of delivered water, despite assurances of safety from suppliers and governments.

UV technologies continue to experience rapid growth in municipal drinking water disinfection applications. In addition, there is a growing awareness of UV-based advanced oxidation processes for treating micropollutants in water, including treatment of taste and odor-causing compounds and associated algal toxins.

Several municipalities have installed full-scale UV-oxidation systems for simultaneous disinfection and treatment of taste and odor and algal toxins. These include the cities of Neshaminy PA (15 MGD), Patoka Lake, IL (10 MGD), Alliance, Ohio (10 million gallons per day [MGD] peak flow) and Shenango PA (16 MGD peak flow). The combination of UV and hydrogen peroxide initiates an oxidation reaction that destroys T&O-causing chemicals and increases the level of disinfection. Performance testing was performed on the installations between December 2006 and November 2012.

The presentation will introduce the learner to the science of UV-oxidation as well as the application to municipal drinking water plants. Data from performance validation studies will be presented showing the effectiveness of T&O-compound reduction. Actual T&O reduction data collected are compared to results of predictive models. In addition, data will be presented on LT2 compliance and T&O technology selection process for Otter Lake Water Commission in Virden, Illinois.
