Full Description
Ultraviolet light (UV) has been receiving increased attention in the drinking water industry for disinfection and oxidation applications. Many water utilities that use Lake Michigan as a source water have experienced taste and odor problems for the past several years. In an effort to control taste and odor, the application of UV treatment was examined. Destruction of geosmin and MIB was not very effective using either low-pressure or medium-pressure UV alone. These results were not unexpected given the fact that neither geosmin nor MIB absorb light significantly in the range where the UV lamps emit most strongly. However, under UV/H2O2 advanced oxidation, MIB and geosmin were reduced from 25 and 10 ng/L respectively, to non-detectable levels at a peroxide dose of 2 mg/L and UV doses of ~1000 and
