Abstract
PURPOSE: To obtain treated water of high quality while reducing the amt. of a regenerating agent used by subjecting anion and cation exchange resins to back washing, separation in layers and regeneration in a regeneration tower; packing the esp. highly regenerated lower part of the cation exchange resin layer into the bottom part of a desalination tower; and packing the anion exchange resin and the remaining cation exchange resin on the above resin.
CONSTITUTION: Condensed water 2 is fed from the top of desalination tower 1, passed through first cation exchange resin layer (a), anion exchange resin layer (b), and second cation exchange resin layer (c) in order, and drained as treated water 3. The resins are then back-washed, separated into layers, and regenerated in a regeneration tower. Thereafter, using the lower part of the regenerated cation exchange resin layer, layer (c) is formed. The lower part is relatively well regenerated and mixed with no anion exchange resin. Layer (a) is formed with the remaining resin.
