【 摘 要 】

The main technology for obtaining desalted water is ion-exchange technology. In the process of regeneration and washing of ion-exchange filters, a large amount of waste water containing various compounds is formed. The article presents the composition of wastewater generated at the water treatment section of Sterlitamakskaya Combined Heat and Power Plant (CHPP) at the stages of regeneration and washing of anion-exchange resins. It is shown that the wastewater of anion-exchange filters contains in a large amount of sodium sulfate, sodium chloride and sodium hydroxide. Recommendations for equalizing these waste waters for their processing in a membrane cell are given.
