Effective photocatalytic disinfection of drinking water using TiO2and WO3 coated on fixed plates
In this work, two different nano-scale photocatalysts (titanium dioxide TiO2- Tungsten oxide WO3) were employed to photocatalytic sterilization of real water samples Compiled from different intakes. Bacterial inactivation was evaluated using the spreading plate technique over plate count agar medium. Raw samples of water were compiled from three different intakes of water treatment plants in Kafr El-Sheikh governorate. The results showed high efficiency in the inactivation rate of bacterial cells during an irradiation time of 240 minutes. WO3 reveals higher photocatalytic efficiency in terms of the survival rate of bacteria which be attributed to its lower bandgap. Catalysts were reused for four continuously cycles and the results proved high stability and a good prospect of reuse.
