Abstract

The calculation results of physicochemical parameters of water by processing stages of the blowdown water of the recirculating cooling system after the devices of hybrid water treatment plants using water preparation before the reverse osmosis plant by the methods of liming, soda-liming, ion exchange are given. The possibility of controlling the quality of the concentrate and permeate of the reverse osmosis plant by changing the physicochemical composition to the membrane processing is shown. The principle of constructing the circuits of zero-discharge multi-purpose hybrid water treatment plants for the production of feed water with different quality for the NPP cycles from the blowdown water of recirculating cooling systems is substantiated. Separation of the mass-salt flow of the blowdown water into two allows to bring the quality of treated water to the standards, imposed on the feed water of the NPP cycles. This can significantly reduce the station discharges into the environment.
