ABSTRACT:
The invention concerns an ion exchange process and system, particularly for the regeneration step following a softening or desalination of aqueous solutions. The regenerant solution is fed in an upward stream through the ion exchanger in a direction opposite to the charging direction, as a sequence of intermittent pulse intervals consisting of pulse flow followed by a period of no flow. During the pulse flow, there is limited hydrodynamic lifting of the ion exchange resin beds in layers, followed by subsequent sedimentation during the pause period, without mixing of the layers.
