The disposal of untreated industrial wastewater is posing a great threat to the environment, especially in developing countries. The effluent of the sugar mill is highly alkaline and polluted, thus adversely affecting the environment. Various attempts were done by previous researches, but were ultimately found to be uneconomical when applied on a larger scale. Therefore, this study was designed to investigate the treatability performance of aluminum chloride, as it is abundantly in the local market at a cheaper rate. The results of this study conclude that the optimum dosage of aluminum chloride, i.e., ۷۰ mg/L, can effectively reduce the concentration of COD and TSS by ۶۸ and ۷۸%, respectively, at cost of ۰.۸۵ USD/L.
