Acid dye removal from industrial wastewater by adsorption on treated sewage sludge

International Journal of Environment and Waste Management (IJEWM), Vol. 7, No. 1/2, 2011

Abstract: This study investigated the suitability of sewage sludge for the removal of Acid Blue 93 industrial wastewater. Washed sewage sludge (WS) and sludge activated carbon (AS) were used as adsorbents. The effect of pH, contact time, adsorbent dose and adsorption temperature was studied. Equilibrium isotherms for the adsorption were analysed by Freundlich and Langmuir isotherm models. The pseudo-first-order, pseudo-second order, intra-particle diffusion and Bangham models were used to describe the adsorption kinetics. The results reveal that adsorption using AS show better results (removal 96.57%) than WS, while both adsorptions depended on pH, contact time and adsorbent dose.
