Abstract: An apparatus and method for regenerating spent ion exchange resin and recovering regenerant fluid is described. A regeneration system has a regeneration vat, a regeneration solution tank, a regenerant recovery tank, a chemical dispenser, a solids separator, a pH adjuster and a pump. The regeneration vat holds the spent resin and is connected to the regeneration solution tank to allow transfer of regenerant solution into the regeneration vat. Spent regenerant fluid travels to the regenerant recovery tank, where it is treated with chemicals provided from the chemical dispenser. The solids separator receives the treated regenerant liquid and separates precipitate flocs from the treated regenerant liquid. The concentration of chloride ions in the separated regenerant solution can be adjusted by the pH adjuster to form fresh regenerant solution. The pump pumps the fresh regenerant solution to the regenerant solution tank to regenerate additional spent cation exchange resin.
