Electrophotocatalytic wather disinfection

This work focuses on the photoelectrocatalytic water disinfection by applying electrical voltage onto an electrode system. Working electrode consist of electrical conductor covered by thin film TiO2, because of its very important photoactivity. Disinfection effect was monitored on Gram-negative bacteria E. coli under different conditions. Inactivation of bacterial cells in contamined aqueous solution, first experiment was observed only with presence of oxygen, later reactor was irradiated with UV-A compact blacklight with intensity of 4 mW• m-2 or electrical voltage of 1V was applied to electrode. By adding both effects at the same time I was verifying photoelectrocatalysic water disinfection on chosen microorganism
