DECOLOURIZATION AND DECHLORINATION OF A PULP AND PAPER INDUSTRY EFFLUENT BY THELEPHORA SP.K. Selvam, K. Swaminathan, K.Rasappan, R. Rajendran and S. PattabhiAbstract The white rot fungus Thelephora sp. was newly isolated from the Western (Ghats region of Tamil Nadu, India, and used to treat pulp and paper industry effluents in a laboratory scale and in a pilot seale. This fungus has been shown to degrade a variety of persistant environmental pollutants. To develop in the laboratory scale, a maximum decolorization by 43.1% was achieved on the fourth day. Inorganic chloride at the concentration of 751 mg/L. which corresponded to 220.9% of that in the untreated effluent, was liberated on the tenth day. The chemical oxygen demand (COD) was also reduced to 1,840 mg/ L (45.0%). In the pilot scale, a maximum decolorization by 23.6% was obtained with the one day incubation, inorganic chloride 361 mg/L (54.3%) was liberated on the sixth day and the COD was reduced to 2,000 mg/ L corresponding to 40.2%. From the results, it seems to be one of the efficient candidates for dechlorination of wastewater.
