Abstract
The present study is focused on a Common Effluent Treatment Plant (CETP) located at Umaraya, District Baroda. Waste water from about thirty five small and medium scale industries majorly comprising of chemical manufacturing and pharmaceutical industries are treated in this CETP. The incoming wastewater was collected and mixed to prepare samples. They were then oxidized by Fenton’s reagent (Fe 2+ /H2O2) reduction in COD and BOD were observed at different H2O2 and FeSO4 doses to determine the optimum values. Thereafter pretreated wastewater was subjected to filtration with ordinary charcoal and COD and BOD reductions were noted.COD and BOD reduction of 64.35% and 68.57% respectively was achieved by Fenton’s reagent and after filtration the values were well within the disposal standards. The results clearly indicate that conventional system should be replaced by physicochemical process like oxidation and filtration.
