The basic purpose of resin regeneration is to restore the exhausted resin back to its proper ionic form for service. Although there are various manuals and sources that contain information on how to regenerate resins, for many, guessing plays a major role in this process. To eliminate the guess factor from the resin regeneration equation, this article will provide an overview of the basic regeneration procedures and guidelines for softeners and two-bed deionizers.

Higher pH solutions, through the addition or use of alkalis such as sodium hydroxide, sodium bicarbonate or sodium carbonate, will result in severely decreased uranium regeneration.

Frequently there are inconsistencies between the effectiveness of two regenerations even though the same procedure was followed.
Ion exchange resins are regenerated every day, and whether regenerating in huge vessels or regenerating in small laboratory columns, mixed beds or two beds, the object of the regeneration is the same: to restore the exhausted resin back to its proper ionic form for service.
