Abstract
The thermal desalination technology is considered one of the most environmentally friendly and perfect for the preparation of steam turbine additional water. The purging water of the evaporative unit is an alkaline, highly mineralized, intensely colored solution, in which sodium salts (sulfates, chlorides) and alkali are mainly contained. The total salt content exceeds 30 g/kg. There is significant content of organic substances, silicates. A technology has been developed for processing of a thermo-desalting complex excess purge water by electromembrane methods to produce alkali and softened water. A schematic solution of the electromembrane utilization of purge water excess from an evaporator water treatment plant is presented.
