Abstract: A water demineralizer system and method is provided in which at least three beds of resin particles are connected in series flow arrangement preferably within a single vessel for substantially removing metal ions such as calcium and magnesium from water feed by exchange with hydrogen ions. The raw feed water flows first through an upper cation resin bed, then through an intermediate anion resin bed, and then through a lower bed of mixed cation and anion resins, and preferably flows downwardly through the beds. After the resin beds become saturated with metal ions from the feed water, mainly by calcium and magnesium ions, the beds are regenerated by first backwashing with water, then chemically treating with acid and caustic solution, followed by bed rinsing, air mixing and backflushing with water prior to further use for demineralizing the feed water.

Abstract: A process is disclosed in which a spent mixed anion/cation exchange resin bed is hydraulically separated into cation, anion and interface resin cuts. The interface resin cut is further classified by various physical separation techniques. Cation and anion resins are separately chemically regenerated. In an alternative embodiment cation resin fines are physically separated from the anion resin cut.
