Wastewater by Coagulation and Activated Sludge Process

Abstract

Treatment of Automobile Service Station Wastewater by Coagulation and Activated Sludge Process The present study is aimed to explore the pollution potential of automobile service station wastewater and to treat the same. The wastewater samples were collected from different servicing points of a typical automobile garage and then characterized for parameters like pH, Total solids, Total Suspended Solids, Chemical Oxygen Demand (COD) as well as Oil and Grease.

A composite sample was also prepared on the basis of wastewater generation pattern. The characterization results revealed that oil and grease and COD were two major pollution parameters of concern. The composite oily wastewater was firstly treated using coagulants like alum, FeSO4 and CaCl2 .

Conclusion

This paper presents the characterization and treatment methods adopted for treatment of automobile waste  water. COD and Oil & grease were taken as the crucial parameters in the automobile effluent. Use of chemical and physical methods of treatment using sugarcane bagassse and saw dust for different column heights was explored.
