Full Description

This powerpoint presentation begins by providing a brief overview of taste and odor in drinking water and the dual purpose of ultraviolet- (UV)- based advanced oxidation process (AOP). Kinetic experiment conditions are presented, along with a reactor scale-up study, modeling input parameters, direct UV photolysis, UV-Hsub2/subOsub2/sub AOP, and UV-Hsub2/subOsub2/sub alternatives in drinking water treatment plants (WTPs). Presentation conclusions indicate that: geosmin, 2-MIB, pyrazines and anisoles were successfullyreduced to below OTC levels using UV-Hsub2/subOsub2/sub and UV-HOCl;in UV-Hsub2/subOsub2/sub scale-up study, natural organic matter (NOM) and Hsub2/subOsub2/sub dose weremajor key factors, rather than pH and carbonate alkalinity;T UV-NOsub3/subsup-/sup (4) UV-Hsub2/subOsub2/sub (9) UVHOCl(40); and,the result leads to the possibility of using HOCl togetherwith UV in an AOP system; however, a potential problemis disinfection byproduct (DBP) formation due to high chlorine doses. Includes tables, figures.
