ABSTRACT:
The invention 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 is disposed at the other end of the vessel, having a cathode at the inside of the cathode chamber. At lease one diluting chamber and at least one concentrating chamber are located alternately between the anode chamber and the cathode chamber. The diluting chamber has an anion exchange membrane on the anode chamber side and a cation exchange membrane on the cathode chamber side. The diluting chamber has an inlet for water to be treated and an outlet for demineralized water. The concentrating chamber has an inlet for water and an outlet for ion-concentrated water. The diluting chamber contains a cloth comprising a mixture of strongly acidic cation exchange fibers, strongly basic anion exchange fibers and ionically inactive synthetic fibers. Preferably, the mixture contains from 20 to 70% by weight ionically inactive synthetic fibers.
