Abstract

Inflow branch pipes of water to be treated, which are branched from an inflow line of the water to be treated, which is provided on an upper side of desalination chambers of an electrodeionization apparatus, communicate with the desalination chambers, respectively. Both ends of the inflow line of the water to be treated are opened, and a supply pipe of the water to be treated communicates with each of the ends so that the water to be treated can be supplied from both sides. In addition, in a lower side of each of the desalination chambers, outflow pipes of treated water, communicate with each other, and these outflow pipes each join an outflow line of the treated water. In addition, both ends of the outflow line of the water to be treated are opened so that the treated water can be discharged from both sides. According to such an electrodeionization apparatus, it is possible to suppress an increase in a differential pressure during passage of water.
