Treatment of Sugarcane Industry Waste Water by Combination of Chemical Coagulation and Activated Carbon
Treatment of Sugarcane by Waste Water
Keywords:activated carbon, alum, BOD, coagulation, COD
The study was designed to treat the effluent from sugarcane sector. The use of fresh water in sugarcane industry and result huge amount of waste water is not a secret to anyone. The use of chemicals in large quantities has caused a great risk and damage to the groundwater, soil, and aquaculture and ultimately leads to the destruction of our environment. Treatment of industrial sugarcane wastewater is not an easy task it has becomes a challenging task for environmental scientist. The purpose of our study is treatment, time saving and reuse for irrigation purpose. Coagulation with alum, ferric chloride, ferrous sulphate with combination of activated charcoal technique was used. The results of the study disclosed that COD and BOD were in huge amount and were successfully treated. Results of COD and BOD removal efficiencies were 51 and 28 mg/L, 76 and 42 mg/L, 90 and 52 mg/L by using alum, ferric chloride and ferrous sulphate respectively with combination of activated charcoal. After treatment, the effluent was very clear and met the requirements of National Environmental Quality Standards. Subsequently, using coagulation with combination of adsorption technique proved very effective, time saving, harmless technique for industrial sugarcane wastewater treatment.
