Systems and methods for regenerating and restoring kinetic properties of resins

摘要

Systems and methods configured to restore ion exchange kinetic properties and purify resins are described. The degraded ion exchange kinetic properties of the anion resin eventually lead to impurity leakage through the resin charge. These systems and methods utilize an acid catalyst with a sulfite scrubbing solution to remove organic material and protonate iron oxide for decomposition and removal from anionic resins. When the cleaning solution is applied through the cleaning vessel utilizing the eductor(s)/plenum and wedge-wire screen draw chamber, electronic monitoring controls all steps of the cleaning while fully controlling the ion exchange kinetics of the usable resin. restore As such, the system and method provide a safe, effective and greatly improved method for restoring anion resin kinetics and improving regeneration quality, for improved resin performance and minimization of resin replacement costs.
