摘要：A stratified bed of ion exchange resins is regenerated by countercurrent orupflow regeneration. Expansion of the bed is prevented by returning used regenerantsolution to the top of the bed and pumping the returned regenerant solutiondownwardly through the layer of resin at the top of the bed. Recycling of the usedregenerant solution also regenerates the upper layer of resin.
