Abstract
Sorbable ions are removed from aqueous compositions by the use of an apparatus and method which permits the aqueous composition to flow in an uninterrupted or continuous manner. Included is a resin cycling contactor assembly which continuously accepts the flow of aqueous composition and which turbulently contacts it in a generally co-current elongated contactor path during which ions are removed from the aqueous composition and sorbed to the resin. The resin cycles within the resin cycling contactor assembly until a selected degree of resin contamination is achieved, at which time a predetermined portion of the resin is removed from the resin cycling contactor assembly and replaced by regenerated resin. The resin is regenerated within a regenerator assembly which accomplishes regeneration by counter-current flow of liquids through a packed resin bed.
