Pilot-scale regeneration of wastewater through intensified sulfate radical-based advanced oxidation processes (PMS/UV-A, PMS/H2O2/UV-A, and PMS/O3): Inactivation of bacteria and mechanistic considerations

•Intensification of SR-AOPs in wastewater effluents was assessed.•Combination of PMS with H2O2 and O3 showed positive effects on disinfection.•In PMS/H2O2/UV-A, the predominant radical depended on the oxidant molar ratio.••OH is predominant in a molar ratio 1:1, and SO4•- in a ratio 1:3 (PMS:H2O2).•The treatments are able to remove simultaneously different bacteria strains.
