Abstract: This article presents a detailed analysis of the quantitative and qualitative parameters of industrial wastewater from the “Navoielektrokimyo” Joint Stock Company. The analysis revealed that the wastewater contains a high concentration of dissolved salts, suspended solids, and other pollutants that exceed permissible environmental standards. In order to address this issue, laboratory experiments were conducted using activated samples prepared by thermal treatment of defecate and bentonite. The performance of these samples was evaluated based on changes in pH, turbidity reduction, sorption capacity, and overall purification efficiency. Special attention was paid to the modification techniques and roasting temperatures used in the activation process. The research demonstrated that thermally activated sorbents based on defecate and bentonite are cost-effective, environmentally friendly, and technically efficient for reducing the pollutant load in industrial effluents. These findings suggest that such modified natural materials hold significant promise for application in sustainable wastewater treatment technologies
