Abstract

The waste effluents discharged by the paper pulp industry contain variety of toxic contaminants which have gained a lot of attention worldwide because this is regarded as major source of pollution. Various methods have been used to reduce COD, BOD, lignin, phenol, colour etc. from textile effluent by many researchers which include chemical oxidation, Fenton’s process, ozonation, wet air oxidation, hydrogen peroxide oxidation, bio-degradation, etc. In this review paper we have mainly focused on the biological methods which are eco-friendly and efficient. The scattered research work related with the biological treatment of textile effluent has been compiled to explore the most suitable, eco-friendly and efficient method for the removal of COD/BOD, phenol, lignin, colour, etc. along with their positive and negative aspects which would be helpful for the researchers and industries to explore new dimensions.
