ABSTRACT:
An ion exchange system having a number of vessels containing beds of ion exchange material that remain in the same vessel during exhaustion and regeneration is operated so that the efficiency of exhaustion and regeneration is increased and the amount of time the vessels and ion exchange material stand idle is reduced. A number of vessels are connected in parallel in service while other vessels are connected in series for regeneration. Vessels with freshly regenerated ion exchange material are connected in series with the service vessel containing the most nearly exhausted bed of ion exchange material while that bed is being substantially completely exhausted.
