Abstract

Abstract : The aim of this study was to consider the efficiency of the electro‐Fenton process for organic compound reduction in an industrial dairy effluent. Experiments were conducted to evaluate the effect of several parameters, such as reaction time, pH, H2 O2 /Fe 2+ molar ratio and volume fraction of H2 O2 to dairy wastewater (mL/L), on the process performance. The Taguchi technique was applied to investigate the optimum operating conditions. The optimum chemical oxygen demand removal (93.24%) was experimentally obtained at a pH value of 7.58, reaction time of 87.13, current density of 58.5, H2 O2 /Fe 2+ molar ratio of 3.62 and volume fraction of H2 O2 to dairy wastewater of 1.39 mL/L.
