As the bed exchanger production diagram suggests, a mixed bed demineralizer is demineralized in which the cation and anion resin beads are mixed. It is equivalent to several two-steps demineralizes in series. In this demineralized, more impurities are replaced by hydrogen and hydroxyl ions, and the produced water can be extremely pure. It should be noted here that a demineralization water treatment plant uses a DM Water System. As the graphical illustration signifies, a DM Water System produces mineral-free water by operating on ion exchange, Degasification, and polishing principles. Demineralized Water System finds wide application in steam, power, process, and cooling. Raw water is passed via two small polystyrene bead-filled (ion exchange resins) beds.
