description PURPOSE. Development of technological solutions to reduce the amount of wastewater and reuse them in the cycle of the modernized water treatment plant at the Sterlitamak thermal power plant.METHODS. To achieve this goal, the methods of system analysis of the chemicaltechnological system were used, the sources and transformation of pollutants were determined.RESULTS. To date, Russia has experience in the disposal of wastewater from water treatment plants of energy enterprises. Basically, this method is based on neutralization with the use of various additional chemical reagents. As a result of the analysis, variants of technological schemes of a modernized water treatment plant were presented, where the concentrate after the reverse osmosis installation undergoes additional purification with the use of H- and Nacationite filters with joint or local use. The variant of the technological scheme will directly depend on the qualitative and quantitative composition of wastewater. A gypsum reactor is provided for the disposal of acidic waste regeneration solution, where gypsum is obtained as a product. These technological schemes make it possible to purify the wastewater of the installation and reuse it. These schemes are low-cost and are promising directions for the development of stations. conclusion. The developed technological solutions do not require the purchase of expensive chemicals and equipment, but only require the re-binding of equipment and the presence of a contact tank. These technologies are resource-saving, as a result, the consumption of raw water is reduced due to the reuse of waste, i.e. the cycle is low-flow. In recent decades, many industries have switched to a low-waste policy, since wastewater carries a large amount of valuable substances that can be recycled and reused.
