This work assessed the applicability of UV/TiO2/O3 processes in photo reactors column type for disinfection of secondary effluents of ETE pilot UASB + Wetland of UNISC. The reactors were tested with the same detention times of 0 to 60 minutes, both fed with the studied secondary effluents in pH=7. The tests were carried out with a recirculation time of 1 hour, flow of 180 L h-1, germicide lamps of 30W. The obtained results showed the applicability of the reactors type column for disinfection of treated sewage, obtained total disinfection in HDT’s of 12 minutes, from the inactivation of thermo-tolerant coliforms. Also, the experiments using the UV/TiO2/O3 process had demonstrated to greater capacity of oxidation in function of the reductions of total alkalinity and turbidity, indicating major potentialities for the disinfection.Downloads
