| description | An electric deionization device capable of sufficiently removing weak electrolyte components and producing processed water with sufficiently high specific resistance, comprising a desalting chamber having a rectangular-parallelepiped frame (20), a compartment member (21) disposed in the frame (20) and, desirably, having conductivity, an ion exchange resin (23) filled in small chambers (22) formed by the compartment member (21), and an anion exchange membrane (24) and a cation exchange membrane (25) disposed so as to hold the frame (20). The compartment member (21) is formed in a hexagonal honeycomb shape. The ion exchange membrane (23) is the mixture of an anion exchange resin with a cation exchange resin, and its mixing ratio on the upstream side is different from that on the downstream side. |
