Description
The UV/H<sub>2</sub>O<sub>2</sub> advanced oxidation process was evaluated for removal of methyl-isoborneol(MIB) and geosmin in three natural waters with a total organic carbon (TOC) concentration range of 1.7 to 3.0 mg/L.The results, after accounting for volatilization, showed MIB removals ranging from 5% to 96%and geosmin removals ranging from 22% to 98%. Increasing the H<sub>2</sub>O<sub>2</sub> dose from 2 to 5 mg/Lresulted in an additional 20% removal for both compounds. Increasing the UV dose from 200 to500 mJ/cm<sup>2</sup> resulted in an additional 29% removal for both compounds, while increasing the UVdose from 500 to 1000 mJ/cm<sup>2</sup> resulted in an additional 14% removal for both compounds. Theinitial TOC, alkalinity and turbidity were found not to have an impact on the removal. Theexperimental results were compared to those predicted by a UV model (Rosenfeldt et al., 2005).The model under-predicted both MIB and geosmin removal seen in the experiments and could beused as a conservative prediction tool for a UV/H<sub>2</sub>O<sub>2</sub> advanced oxidation process. Includes 2 references, tables, figures.
