ΠερίληψηIn this study, the semiconductor photocatalytic disinfection of spring water and of secondary treated municipal wastewater was investigated. Natural water from a spring in Chania prefecture, which is used for the water supplies for the city of Chania, Crete, and samples from the effluents of the secondary settling tank of the municipal wastewater treatment plant of Chania were collected. The samples were exposed to UV-A irradiation in the presence of TiO2. The parameters examined in this study were the length of TiO2 / UV-A treatment for effective disinfection, the microorganism type (total coliforms, enterococci), the relative bactericidal activity of three different types of TiO2, the amount of the catalyst needed, and the pH of the samples. The results presented here show that commercial TiO2 powder Degussa P25 is the most effective catalyst of the three used. Enterococci showed a stronger resistance to photocatalytic disinfection, whereas small pH changes do not seem to have a significant effect on it.en
