PURPOSE:To reduce high-electric conductive liquid waste, by reserving it in liquid waste tanks annexed to columns for regenerating both of cation and anion- exchange resins, and using it for the regeneration of said ion-exchange resin. CONSTITUTION:Liquid waste tanks 32, 33 for high-electric conductive liquid waste are annexed to a cation-exchange resin regenerating columns 3 and an anion-exchange resin regenerating column 4. In the regenerators connected to a column 1 for the desalination of condensed water, low-electric conductive liquid waste is reserved in a liquid waste tank 2 directly connected to the desalinator column 1, while high-electric conductive liquid waste is reserved in the liquid waste tanks 32, 33 directly connected to the regenerator columns 3, 4 and used for the regeneration of ion-exchange resins. Thus, an amount of water to be used is saved. |
