    Abstract: Systems and methods for regenerating mixed bed demineralizers are disclosed in this invention. Ion exchange resins are separated in a separation vessel and are separately regenerated in a regeneration vessel. No inert resins are required for separation. Fluid purification and resin regeneration may occur simultaneously, without the use of additional storage tanks or vessels.

    CPC classification number: B01J49/09

    Abstract: In the regeneration of a mixed bed of cation and anion resins which are separated into layers, these being individually regenerated, the effluent regenerant of the anion layer is collected at points above the interface between the layers and the regenerant of the cation layer is introduced at points below the interface. A central device for collecting and distributing regenerant has inlets on the upper side and outlets on the under side, and all the inlets and outlets are controlled by nonreturn valves.

    Abstract: IN THE REGENERATION OF MIXED-BED ION EXCHANGE RESINS, THE RESINS ARE FIRST SEPARATED IN THE CONVENTIONAL MANNER BY AN UPFLOW OF LIQUID. THE RESINS ARE THEN ISOLATED FROM ONE ANOTHER, AND CONTAMINANT CATION EXCHANGE RESIN IS SEPARATED FROM THE ANION EXHANGE RESIN BY FLOATING THE ANION EXCHANGE RESIN IN AN INTERMEDIATE-DENSITY LIQUID HAVING A DENSITY INTERMEDIATE BETWEEN THE CATION AND ANION EXCHANGE RESINS. THE CONTAMINANT CATION EXCHANGE RESIN SINKS TO THE BOTTOM OF THE VESSEL, PERMITTING THE ANION EXCHANGE RESIN TO BE READILY ISOLATED.
