Title: Process for removal of undissolved impurities from ion exchange resin
IPC: B01J49/00
Filed: 1977-02-22
Abstract: A process for scrubbing undissolved impurities from the upper portion of an ion exchange resin filtration bed is disclosed wherein air is introduced in the upper portion of the bed and develops a pressure within the vessel.
