Abstract Coagulation, adsorption and disinfection methods were used for purification of wastewater from effluent treatment plant (ETP) of ICAR-National Dairy Research Institute, Karnal, India. The application of alum @ 1 g/L), charcoal @ 0.5 g/L and chlorine @ 1% were found to be the effective dosages for wastewater treatment. The alkalinity, total hardness, total dissolved solids (TDS) and biochemical oxygen demand (BOD) reduced (P<0.05) and were, 146.4 mg/L, 125 mg/L as CaCO3, 480 mg/L and 0.88 mg/L (3 days at 27°C), respectively after treatment. The different physico-chemical properties (colour, odour, pH, alkalinity, hardness, TDS, BOD, nitrates and chlorides) of treated water samples were well within the permissible limits of different water quality standards.
