摘要

Disclosed is a demineralization apparatus comprising: an anode chamber disposed at one end of a vessel having an anode at the inside of the anode chamber; a cathode chamber disposed at the other end of the vessel having a cathode at the inside of the cathode chamber; and at least one diluting chamber and at least one concentrating chamber, disposed alternately between the anode chamber and the cathode chamber, the diluting chamber having an anion exchange membrane on the node chamber side and a cation exchange membrane on the cathode chamber side, the diluting chamber having an inlet for water to be treated and an outlet for demineralized water, the concentrating chamber having an inlet for water and an outlet for ion-concentrated water, the diluting chamber containing a cloth comprising a mixture of strongly acidic cation exchange fibers, strongly basic anion exchange fibers and ionically inactive synthetic fibers.
