Toward the Development and Optimization of a Solar Photo-Fenton Degradation Method for Natural Organic Matter Removal in Selected South African Drinking Water Treatment Plants.

ABSTRACT: Natural organic matter (NOM) is one of the major pollutants of concern in drinking water. In this study, the photo-Fenton process was applied for enhanced removal of NOM in drinking water samples collected from four drinking water treatment plants (DWTPs) in the KwaZulu-Natal Province of South Africa. The photo-Fenton process for NOM degradation was performed at pH 3 and a 3:10 ratio of Fe-(II) to H₂O₂ under simulated solar light. Up to 73% UV₂₅₄ reduction and 54% DOC removal after 20 min of irradiation were achieved in batch experiments. A specific ultraviolet absorbance (SUVA) value of 0.89 L/mg·m was attained, which is characteristic of low-molecular-weight organic compounds. Ring-opened oxidation products were detected using the gas chromatography time-
