Abstract: A system and method configured to restore ion exchange kinetic properties and purify resin is described. Degraded ion exchange kinetic properties of anion resin will eventually result in impurity slippage through resin charges. This system and method employs an acid catalyst in combination with sulfite cleaning solution to remove organic material and to protonate iron oxides for deconstruction and removal from anion resins. The cleaning solution, when applied via a cleaning vessel utilizing an eductor(s)/plenum and wedge-wire screen draw chamber, while controlling all phases of cleaning by electronic monitoring, yields complete restoration of ion exchange kinetics on usable resin. As such, the system and method provides a safe, effective, and vastly improved method for restoring anion resin kinetics and improving regeneration quality, for improved resin performance and minimizing resin replacement costs.
