—In this study, a photocatalytic oxidation system was used for the disinfection of water used in a real estate in Hong Kong, two types of domestic water namely fountain water and flushing water were used in study to test the disinfection effectiveness done by photocatalytic oxidation system. Chlorine was used in the photocatalytic oxidation system for disinfection which is using RuO 2
electrolytic and TiO2
photocatalytic system. This study was used to evaluate the formation and the disinfection efficiency of the free chlorine generated by the photocatalytic oxidation system under different electric voltages of 10, 20 and 30V. Experimental results revealed that under electric voltage of 25 to 30V, the best disinfection effect could be achieved.
