SOLAR PHOTOCATALYTIC DECONTAMINATION AND DISINFECTION OF WATER

Photocatalysis using TiO2 for detoxification of contaminated water is most extensively been studied and developed today as of its practical applications to treat water contaminants. Photocatalytic treatment can be useful for addressing hazardous contaminants such as phenols, agricultural wastes, pesticides and etc. The objective of this study was to demonstrate whether detoxification of pesticide contaminated water by TiO2 photocatalysis process is possible. The performance of photocatalytic degradation of pesticide contaminated groundwater has been studied at pilot scale with the TiO2 photocatalyst. The study showed that 80 % and 54 % mineralization has been attained after 24 hours of UV and solar radiation, respectively.
