Removal of reactofix supra red HBSL from industrial effluent using electrochemical and adsorption techniques
Many industries use dyes and pigments to colour their products. The largest customers of these dyes are textile, tannery, paper and pulp, pharmaceuticals, cosmetics, food processing units and they are in turn the most serious polluters of our environment. The proper treatment of aqueous wastes is fundamental for the preservation of environmental equilibria and the quality of aquatic systems. Electrochemical techniques and adsorption methods offer good potential to remove colour from wastewater. In the present work both the electrochemical and adsorption methods were applied for colour removal and comparative results are presented. Effectiveness of using low cost adsorbent wheat husk was explored.
