Industrial development bad to the damage of environment and ecosystem and it results in the pollution of air, soil and water since water is a universal solvent the industrial are using it as trade effluent. A large number of starch factories based on tapioca (sago) are located in three southern states of India- Kerala, Karnataka and Tamil Nadu, waste water treatment is the process of removing contaminants form waste water. They are done by Physical, Chemical and biological process. To treat this they will use coagulants by doing flocculation sedimentation and filtration process. They generally use chemicals coagulation such as Alum, Ferric chloride and poly Aluminum chloride. The dosage level of all product were take as same and we calculated their efficiency of removing the turbidity and other concerns such as characteristics of sago waste water. Here we had adopted the most effect natural coagulant for treatment process of sago effluent.
