DEVELOPMENT OF RESOURCE-EFFICIENT TECHNOLOGIES FOR PROCESSING ACIDIC AND SALINE INDUSTRIAL LIQUID WASTES INTO VALUABLE PRODUCTSI

This study presents the development of physico-chemical and technological principles for the processing of acidic and saline liquid industrial wastes. The research focuses on spent sulfuric acid, saturated diethylene glycol, and neutralized industrial wastewater. Based on thermodynamic analysis and solubility diagrams, resource-efficient technologies were developed to obtain valuable products such as potassium sulfate, burkeite, purified water, and regenerated DEG. The proposed approaches demonstrate high efficiency and environmental safety.
