【発明の名称】電気脱イオン化装置
Document Type and Number:
Japanese Patent JP3009221
Kind Code:
B2
Abstract:
An electrodeionization apparatus is provided for removing ions from liquids. The apparatus is particularly well adapted for the removal of large, heavily hydrated, highly charged or weakly ionized molecules or complexes from feed water. Such removal is achieved by substituting, in at least one section of the apparatus, ion exchange membranes and/or resins having lower crosslinking and/or lower selectivity, for the ion exchange membranes commonly used in electrodeionization systems. Methods for reducing the electrical resistance across the membrane also are provided.
