Abstract
Assessment of Physicochemical Characteristics of Effluents from Paper Mill in the State of Uttar Pradesh, India
Highlights
Industrial discharges have been a major cause environmental pollution and hazardous contamination to soil and surface as well as ground water
The turbidity of effluent samples was measured by using turbidity meter and the readings were recorded as nephlometric turbidity unit (NTU)
The agro-based paper mill under study produces a variety of writing and printing paper using bagasse, wheat straw, and other agricultural residue as a primary raw material
Summary
Industrial discharges have been a major cause environmental pollution and hazardous contamination to soil and surface as well as ground water. The pulp and paper industry is one of the major industries utilizing high quantity of water resulting in the generation of large amounts of wastewater [2]. It is the sixth largest environment polluting industry discharging a variety of pollutants into the environment [3]. The high consumption of fresh water and generation of a huge volume of toxic wastewater are the most important environmental concerns related to the pulp and paper industry. Among the various processes of paper making, pulping especially chemical pulping and pulp bleaching generate highly contaminated wastewater which contains toxic substances such as resin acids, unsaturated fatty acids, diterpene alcohols, juvaniones, chlorinated resin acids and others. Major problems of the wastewaters are high organic content, dark brown colour, AOX and other toxic pollutants [6]
