Treatment of Textile Dyeing Industry Effluent using Activated Carbon

Ashok Kumar Popuri and Prashanti Guttikonda

Methods for treating textile dye wastewaters consist of various chemical, physical and biological processes. Among many decolourisation procedures the adsorption technique gives good results because it can be used for the removal of various types of colored matter. Commercial systems use mostly activated carbon as the sorbent for decolourisation of wastewaters because of its excellent adsorption ability. Although activated carbon has an advantage as a sorbent, its massive employment is restricted due to its high price. To reduce the treatment costs, cheap alternative adsorbents are being sought. In this study activated carbon is used to treat two different textile dyeing industry effluents and studied the effect of parameters like adsorbent dosage, RPM, pH and time.
