Title:
APPARATUS FOR FORMING ION-EXCHANGED WATER AND METHOD FOR REGENERATING ION EXCHANGE RESIN THEREIN
Document Type and Number:
WIPO Patent Application WO/2005/075359
Kind Code:
A1
Abstract:
An apparatus for forming ion-exchanged water which comprises an anode (1) and a cathode (2), and, between the anode (1) and the cathode (2), in the following order from the anode (1) side, an anode chamber (8), an anion exchange resin chamber (10), a bi-polar film (3), an cation exchange resin chamber (11) and a cathode chamber (9), wherein the anion exchange resin chamber (10) is packed with an anion exchange resin (6) and the cation exchange resin chamber (11) is packed with an cation exchange resin (7), and wherein the bi-polar film (3) comprises an anion exchange film (3a) and a cation exchange film (3b), and the anion exchange film (3a) is arranged on the anode (1) side and the cation exchange film (3b) is arranged on the cathode (2) side. The above apparatus allows the reduction of the amount of chemicals, salts and water required for regeneration of an ion exchange resin, which results in the reduction of the cost required for regeneration of an ion exchange resin.
