Emerging micropollutant oxidation during disinfection processes using UV-C, UV-C/H2O2, UV-A/TiO2 and UV-A/TiO2/H2O2

► UV-C leads to a fast disinfection but negligible degradation of micropollutants. ► UV-A/TiO2 disinfection allows the simultaneous oxidation of micropollutants. ► Inactivation of bacteria with UV-C is reversible during dark storage of water. ► UV-A/TiO2 leads to the irreversible inactivation of bacteria. ► Addition of H2O2 improves both UV-C and UV-A/TiO2 processes.
