  • Patent number: 5392921
    Abstract: A resin processing system in which a mixture of resins, preferably a mixture of anionic and cationic resins, is separated by a laminar or essentially laminar flowing fluid through a separator module, wherein the anionic particles are removed from the top of the module, and the cationic particles are removed from the bottom of the module. The separated particles can be reused, with or without regeneration of the resins, or can be discarded. Preferably, the mixed resin is cleaned by use of one or more vibrating screen and rotating sprayers which spray water prior to introduction into the separation module. Furthermore, the cleaned mixture can be used without separation. The resin processing system can be used to clean and separate resins which have been used, or to condition resins which have not been used, in water purification processes.
