Solar-assisted bacterial disinfection and removal of contaminants of emerging concern by Fe2+-activated HSO5- vs. S2O82- in drinking water

•SO4∙- generation greatly reduces the required time for SODIS treatment.•PMS shows a higher efficiency than PDS, using up to three activation factors.•Fe2+ better promotes the catalytic generation of SO4∙- from PMS than PDS.•SO4∙- can remove micropollutants while disinfecting water in low PMS/PDS doses.•The economic analysis supports the feasibility of using PMS/PDS in SODIS treatment.
