| 20080308482 | Electric Deionized Water Production Apparatus - An electric deionized water production apparatus in which a direct current field is applied to a deionizing chamber packed with an ion-exchange material such that ions to be discharged are allowed to migrate in the direction identical or opposite to the direction of the water flow in the ion-exchange material, whereby ionic impurities adsorbed in the ion-exchange material are discharged from the system, the ion-exchange material being a mixture of a monolith-shaped organic porous ion-exchange material and ion-exchange resin particles. The electric deionized water production apparatus has a simple structure that can reduce material cost, process cost, and assembly cost, capable of accelerating migration of the adsorbed ionic impurities to facilitate discharge of the adsorbed ions and free from a deflected flow due to swelling or shrinkage accompanying an ion-exchanging reaction, and from poor contact with an ion-exchange membrane. | 12-18-2008 |
