Inparticular,theaimofthisworkwastocomparativelyassesstheefficiencyofsolardisinfectionand solardrivenAOPs(namelyH2O2/sunlight, TiO2/sunlight, H2O2/TiO2/sunlight, naturalphoto-Fenton)for theinactivationofamultidrug(namelyampicillin,ciprofloxacinandtetracycline)resistant E. colistrain isolatedfromtheeffluentofthebiologicalprocessofanUWTP.DifferentconcentrationsofH2O2(0.588–1.470–2.205 mM),TiO2 (50–100mgL−1),H2O2/TiO2 (0.147mM/50mgL−1, 0.588mM/100mgL−1)and Fe2+/H2O2 (0.090/0.294, 0.179/0.588,0.358/1.176mM)wereevaluatedatpilot-scale(incompoundparabolic collectorreactor)inrealbiologicallytreatedwastewater.Allinvestigatedprocessesresultedina completeinactivation(5-logdecrease)ofbacteriauntildetectionlimit,butthebestdisinfectioneffi-ciency intermsoftreatmenttime(20mintoreachthedetectionlimit)andrequiredenergy(0.98kJL−1)was observedforphoto-FentonatpH4(Fe2+/H2O2:0.090/0.294 mM).Antimicrobialsusceptibilitywastested byKirby-Bauerdiskdiffusionmethod.Ampicillinandciprofloxacin(towhichtheselectedstrainis resistant),cefuroximeandnitrofurantoinwerechosenastestedantibiotics.Noneoftheinvestigatedprocesses affectedantibioticresistanceofsurvivedcolonies.
