An EDI(Electro DeIonization) type water softener is provided to increase a process amount drastically by increasing absorption and movement speed of ion even though particles of ion exchange resin are large. An ion exchange material(20) is filled between a positive ion exchange membrane(11) and an anion exchange membrane(12) of a room which removes salt. Concentration rooms(R1~R7) are installed on external sides of the positive ion and anion exchange membranes. The room for removing salt and the concentration room are arranged in stack structure. A cathode and an anode are respectively in an external side of the stack structure. Ion exchange material is made by ion exchange resin. Ion absorption efficiency is large in the inside of the ion exchange material. And the Ion absorption efficiency is small in the external side of the ion exchange material. |
