World is facing lot of health issues due to industrial wastewater pollution. Increasing population and industrialization are one of the main causes of water pollution. In general, industrial wastewater contains suspended, colloidal and dissolved impurities. Industrial effluent may be either excessively acidic or alkaline and may contain high concentration of coloured matter. In this study, coagulation-flocculation method has been used for minimization of contaminants from sugar industry effluent. Lime has been used in conjunction with poly diallyl dimethyl ammonium chloride (PDADMAC) for reduction of chemical oxygen demand (COD), total dissolved solids (TDS), total suspended solids (TSS) and turbidity. It could remove 97% turbidity, 92.8 % TSS, 95.5% TDS and 90.5% COD from sugar industry wastewater. Scanning electron microscopy (SEM) studies were also performed to support the formation of flocs.
