Abstract: An electrodeionization device (EDI device) with improved performance for removing weak acid components such as boron includes a deionization chamber partitioned by a pair of ion exchange membranes between an anode and a cathode. A grain size of 0.1 mm or more and 0.4 mm or less is defined as small grain size, and a grain size of more than 0.4 mm is defined as large grain size. In the deionization chamber, a large grain size layer made of an ion exchange resin of large grain size and a mixed grain size layer in which an ion exchange resin of large grain size and an ion exchange resin of small grain size are mixed are arranged along a flow of water to be treated.
