Abstract

Pulp and paper mills generate varieties of pollutants depending upon type of the pulping process being used. This paper presents the characteristics of wastewater from South India Paper Mill, Karnataka, India which is using recycled waste paper as a raw material. The raw wastewater consists of 80-90 mg L (-aEuro parts per thousand 1) suspended solid and 1,010-1,015 mg L (-aEuro parts per thousand 1) dissolved solid. However, pH varied from 5.5-6.8. The biochemical oxygen demand and chemical oxygen demand ranged from 200-210 and 1,120-1,160 mg L (-aEuro parts per thousand 1), respectively. Aerobic treatment of raw effluent attribute to significant reduction in suspended solid (range between 25 to 30 mg L (-aEuro parts per thousand 1)) and total dissolved solid (range between 360 to 390 mg L (-aEuro parts per thousand 1)). However, pH, temperature, and electrical conductivity were found superior after treatment. Copper, cadmium, iron, lead, nickel, and zinc were found in less quantity in raw effluent and were almost completely removed after treatment. The dendrogram of the effluent quality parameters clearly indicate that South India Paper Mill does not meet Minimal National Standard set by central Pollution Control Board to discharge in agricultural field.
