Study of Waste Water Effluent Characteristics Generated from Paper Industries (original) (raw)

This paper show the physico-chemical characteristics of effluent discharge from paper and pulp industry. The effluent from the paper industry is characterized by high amount of COD, BOD, TDS, pH, SS, Colour .The samples were collected from the inlet and outlet of the effluent treatment plant of paper mill. The samples were analyzed and compared with the Indian standards of effluent discharge. The effluent before treatment average range contains pH of 8.5±0.278, Suspended Solids of 1720.33±253 mg/lt, Total Dissolved Solids average ranges from 2658.33±81.44 mg/lt, Colour value is 735±108.28 PCU, COD and BOD varies 2420±259.55 mg/lt and 778.33±43.10 mg/l simultaneously. After the treatment of waste water average value of pH is 7.65±0.13, Suspended Solids 58.33±7.63 mg/lt, Total dissolved solids ranges from 1918.33±67.88 mg/lt, Colour value is 224.16±3.60 PCU, COD and BOD ranges from 214±1.73 mg/lt and 24±1 mg/lt, respectively. Result shows that the pH, SS, TDS, Colour, COD, BOD, within...
