This powerpoint presentation begins by providing a brief overview of the Patoka Lake Regional Water and Sewer District, located in Dubois, Indiana. A seasonal taste & odor (T&O) issue is presented, along with an investigation of control strategies that included the adsorption technologies of powdered activated carbon (PAC) and granular activated carbon (GAC), and the advanced oxidation technologies of ozone and ozone/hydrogen peroxide and UV/hydrogen peroxide. PAC jar test objectives are outlined, along with GAC rapid small-scale column tests (RSSCT), and bench-scale testing objectives for both ozone advanced oxidation process (AOP), and for ultraviolet (UV) AOP. A brief cost assessment is included. Includes figures.
