摘要: An apparatus and method for regenerating spent ion exchange resin is described. In one method, a fresh regenerant solution comprising sodium ions and chloride ions is prepared, and passed across spent cation exchange resin to regenerate the spent resin. To recover the spent regenerant solution, a regenerant treatment composition is added to the spent solution to form precipitate flocs, which are then separated out of the regenerant solution. The concentration of at least one of the sodium or chloride ions in the regenerant solution can also be adjusted to form fresh regenerant solution which can be reused.
