TREATMENT OF TEXTILE DYEING EFFLUENT USING TEA WASTE AS ADSORBENT
This work investigates the physico-chemical characteristics of effluent discharge by textile industry from Tirupur. The textile industry effluent is characterized by high amount of COD, BOD, TDS, pH and colour. There are many methods to remove dye and several physicochemical methods have been proposed to remove the pollutants. In water and wastewater treatment adsorption is one of the alternatives. Some of the industries used effective purification and separation technique. Waste tea powder was identified as a low-cost adsorbent for the elimination of the dyes from wastewater. Properties of the tea waste are investigated by FTIR and TGA/DSC analysis. The tea waste is activated thermally and the removal efficiencies were investigated. With the activated tea waste the physcio chemical properties are studied. The experiment analysis resulted in removal efficiencies of 94.6%.
