Wastewater treatment is becoming ever more critical due to diminishing water resources, increasing wastewater disposal costs, and stricter discharge regulations that have lowered permissible contaminant levels in waste streams. The ultimate goal of wastewater management is the protection of the environment in a manner commensurate with public health and socio-economic concerns. The aim of our study is to use natural occurring polymeric coagulant to reduce the chemical oxygen demand and color from the industrial waste water. It was found that 83% of Chemical oxygen demand and 90% of color reduction was observed with chitosan.
