Treatment of Dairy Wastewater Using the Fenton’s Oxidation Process (FOP)

Abstract

Nowadays, there is an increased concern over the treatment of industrial effluents. Advanced oxidation processes (AOPs) can be effective due to the recalcitrant and refractory nature of complex pollutants. AOPs provide a faster means of organic pollutant removal and thus may prove instrumental in reducing the treatment time of wastewater. Dairy wastewater normally has high organic content. This paper includes the study of the effect of Fenton’s oxidation process (FOP) on the degradation of dairy wastewater. Fenton’s oxidation process uses hydrogen peroxide and ferrous sulfate to form a highly oxidizing species called as hydroxyl-free radicals (·OH) which can be used to degrade the pollutants in wastewater. Especially, parameters like initial and final turbidity, pH, odor, COD and the ratio of Fenton’s reagent dose to the volume of sample are considered for the study.
