Industrial wastewater treatment facilities are characterized by high energy consumption, which significantly affects their operational costs and environmental performance. This study analyzes the structure of energy consumption in industrial wastewater treatment plants and identifies key areas for improving energy efficiency. Particular attention is given to aeration systems, pumping equipment, sludge energy recovery through anaerobic digestion, and the implementation of automated process control systems. Quantitative indicators for assessing energy efficiency are presented, including specific energy consumption per unit volume of treated wastewater and per unit mass of removed pollutants. A comparative analysis of conventional and energy-efficient technological solutions demonstrates that integrated modernization measures can reduce electricity consumption by 20–40% while enhancing environmental sustainability and economic performance.
