The possibility of utilizing waterworks sludge as byproduct from water supply treatment plant for the remediation of simulated leachate contaminated with cadmium, dissolved organic matter (COD), and ammonia nitrogen (NH3-N) was investigated through batch study in comparison with conventional sorbents specifically activated carbon and ion-exchange resin Amberlite IR120 Na. Batch sorption experiments of single and multi-components systems were conducted to represent the acetogenic phase (pH= 5.5). Results proved that the sludge, activated carbon and ion-exchange resin are efficient sorbents for removal of cadmium, COD, and NH3-N respectively with removal efficiencies ranged from 35 to 95% for all experiments. Equilibrium isotherms were analyzed using the Langmuir and Freundlich models. Kinetic data were obtained and analyzed using pseudo-first-order and pseudo second-order equations. The sorption isotherm data were fitted well to the Langmuir isotherm and the monolayer adsorption capacity was found as 5.634, 14.908 and 3.938 mg/g for sorption of Cd (II) onto sludge, NH3-N onto resin and COD onto activated carbon respectively.
