Abstract
The present invention provides an improved process for the regeneration of ion exchange gels and resins. Exhausted regenerating solutions from a either a cationic or anionic exchange column are converted into fresh regenerating solutions via one or a combination of electrodialysis units having at least one bipolar membrane. The spent regenerants may be treated in an electrodialytic water splitter, an acid or base purification unit, or any combination thereof, to reclaim as much or as little of the regenerating solution as is required by the particular process.
