| Abstract: |
| The present article illustrates the beneficial reuses of the aluminum-based sludge to close the loop between the sludge waste generation and the sustainable environment. In this study the adsorption behaviors of aluminium based sludge, namely alum sludge (AS) and gravel as low cost adsorbents towards the removal of dye from synthetic wastewater samples were analyzed in fixed bed column. The effects of variable parameters such as column pack depth and influent concentration on the effluent concentrations via breakthrough curves were examined. It is estimated that the removal efficiency and adsorption capacities increased as the initial influent concentrations of the dye decreased for the fixed bed height of the both adsorbents, namely, gravel and AS. Thereafter, a preliminarily results were checked to investigate the feasibility of the adsorption column in Reactive Blue 4 (RB4) adsorption. The maximum adsorption capacities were observed around 4 mg L-1 for sample with pH 7.5 which is the natural pH of the wastewater. However, increasing the initial dye loading increasing the adsorption capacity which reached to 5.5 mg L-1 for the dye loading 27.8 mg L-1 of Reactive Blue 4 (RB4). Thus, the first results will be a valuable strategy in the development of adsorption systems to build up a constructed wetland facility. |
