This study investigates the potential of utilizing sand obtained from demolished waste as an adsorbent for theremovalofMethylene Blue dye from aqueous solutions. With a growing concern for environmental pollution caused by dye contaminants, theneedfor cost-effective and sustainable solutions is paramount. In this research, response surface methodology (RSM) has beenusedforoptimising a variety of water and waste water treatment processes. RSM is a collection of mathematical and statistical techniquesforevaluating the effects of several variables, and obtaining the values of process variables that produce desirable values of theresponse.Sand reclaimed from construction and demolition waste is examined for its adsorption capacity. The experimental procedureincludesbatch adsorption studies under various conditions, such as contact time, initial dye concentration. The results demonstratethatthereclaimed sand possesses promising adsorption properties, with significant dye removal efficiency. The results showedthat Demolishesand was effective in removing MB, with a maximum removal capacity of 93.97% , initial MB concentration of 100 mg/L, andcontacttime of 40min. Equilibrium data are analyzed using isotherm models, and kinetic studies shed light on the adsorptionmechanism.Thisstudy provides valuable insights into the potential application of waste-derived sand as an eco-friendly adsorbent for the removalofdyecontaminants, contributing to both environmental remediation and resource recycling efforts.
