Physicochemical study of Paper Mill Effluent: To asses pollutant release to Environment

Rapid industrialization affects the environment in different ways by discharging large amount of effluent as waste water in the surrounding water bodies causing the serious problems to environment. This paper present the physiochemical characteristics of waste water from the paper industry which is using hosiery cotton and waste paper as a raw material. The waste water from the paper industry is characterized by colour, temperature, turbidity, pH, conductivity, acidity, alkalinity, TDS, total hardness and chloride. The waste water samples were collected from the inlet and outlet of paper mill. The samples were analysed and compared with the Indian standards of effluent discharge. The results shows that the temperature, turbidity, pH, alkalinity, totalhardness and chlorides in the permissible limit while conductivity, TDS and acidity does not meet the standards set by Central pollution control board, India. The selected physiochemical parameters are the indicator of pollution load and provides clues about the further use and recycling of effluent.
