Abstract

The present invention relates to a method and apparatus for regenerating consumed ion exchange resin using an ion separation membrane and direct current electricity. The present invention relates to ion exchange used in pure water treatment facilities, nuclear power plants, and chemical treatment plants in nuclear power plants and thermal power plants. Resin was conventionally recycled by using ion exchange resins that were consumed using acid (hydrochloric acid, sulfuric acid) or caustic soda, but chemical storage tanks, metering tanks, and other auxiliary equipment are required. In order to improve the problem of having to install a wastewater treatment device for a separate wastewater treatment due to a large amount of regeneration wastewater caused by chemicals used during regeneration, the present invention uses an ion exchange membrane and a DC power source. Because the ion exchange resin is electrically regenerated, the regeneration time is The present invention relates to an ion exchange resin electrical regeneration method and apparatus using an ion-permeable membrane which is very short and generates little regeneration waste liquid.
