    Abstract: A frustum filter used for separation of cation and anion exchange resins, which is used in condensate water polishing system or apparatus, wherein said frustum filter comprises a microporous filtering net body (1) which is formed by sintering a mixture of silicon carbide grains and a binder, said net body being provided with a plurality of micropores, the diameter of said micropores being in a range of 50-300 micron, said filtering net body (1) being shaped as an inverted truncated cone and its maximum diameter being in a range of 50-200 cm, the angle between a inner tapered face and a horizontal plane being in a range of 15°-30° and the thickness of said filtering net body being in a range of 2 cm-14 cm. Some reinforcing steel bars which have the property of high temperature resistance are embedded in said filtering net body(1) in advance. A steel ring (6) welded at the housing (2) is fixed on the external circumference of said filtering net body (1). This invention has the following advantages: it can distribute evenly water and has high strength; it can not be blocked easily and will not create dead zones when filtration; the product of the invention has high strength and cannot be deformed easily over the prior art; it also has the properties of strong acid fastness, strong alkali fastness, high temperature resistance, oxidation resistance.

    Abstract: By passing an alkali regenerating agent A through a basic anion exchange resin (3), and through a strongly acidic cation exchange resin (4), the basic anion exchange resin can be regenerated while amphoteric organic materials such as the amino acids captured at the strongly acidic cation exchange resin can be desorbed. Then, an acid regenerating agent B is passed through the strongly acidic cation exchange resin to regenerate the strongly acidic cation exchange resin.

    Abstract: THIS INVENTION RELATES TO THE REGENERATION OF ANION EXCHANGE RESINS USED IN MIXED ION EXCHANGE RESIN BED DEMINERALIZERS WHEREIN THE RESINS ARE SEPARATED, THE ANION EXCHANGE RESIN FRACTION REGENERATED WITH AN ALKALI METAL COMPOUND, AND THE REGENERATED RESINS ADMIXED TO REFORM THE MIXED BED. SPECIFICALLY, THE INVENTION COMPRISES TREATMENT OF THE ANION EXCHANGE RESIN FRACTION AFTER REGENERATION TO REPLACE THE ALKALI METAL CATION ASSOCIATED WITH THE CATION EXCHANGE RESIN PRESENT IN THE ANION EXCHANGE RESIN FRACTION WITH AN ALKALINE EARTH METAL CATION SELECTED FROM THE GROUP CONSISTING OF CALCIUM, BARIUM, STONTIUM, AND MIXTURES THEREOF, AND REMOVING THE ALKALI METAL CATION FROM THE FRACTION PRIOR TO ADMIXTURE OF THE RESINS TO REFORM THE MIXED BED.
