Chemical coagulation and biological techniques for wastewater treatment

Abstract This paper reports the effectiveness of chemical coagulation and biological techniques for treatment wastewater from industrial agricultural operations. Agricultural husbandry has been reported to produce that high content oxygen demand (COD), (BOD), turbidity as well organic inorganic pollutants. A comparison on use based coagulants optimum conditions required percentage removal efficiency pollutants reviewed. At experimental condition, ferric chloride were yield 98, 95, 93 50 % color, turbidity, iron manganese. Moreover, coagulation, electrocoagulation methods have display a close range in their capacities removing wastewater. However, method was observed be highly effective but requires more time produces lesser volume sludge, when compared
