Abstract

In the electrodeionization deionized water producing apparatus, water is passed through a deionizing chamber(s) packed with an organic porous ion exchange material having a three-dimensional network structure to remove ionic impurities in the water, thereby producing deionized water. At the same time, a DC electric field is applied to the deionizing chamber(s) to discharge ionic impurities adsorbed on the organic porous ion exchange material outside the system, wherein the DC electric field is applied so that the ions to be discharged may electrophoretically move in the direction reverse to the flow of water through the organic porous ion exchange material.
