Effect of Fe(II)/Fe(III) species, pH, irradiance and bacterial presence on viral inactivation in wastewater by the photo-Fenton process: Kinetic modeling and mechanistic interpretation
MS2 coliphage inactivation parameters by the photo-Fenton process in wastewater were assessed. Dissolved Organic Matter did not inhibit the photocatalytic MS2 inactivation at near-neutral pH. Increased iron presence by DOM complexation enhanced the inactivation of MS2 virions. In presence of their bacterial host, the competition for oxidants delayed MS2 inactivation. An integrated mechanism for the MS2 inactivation in wastewater was proposed.
