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.

Abstract: 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.

Abstract: The disclosed systems and methods for maintenance of an enclosed body of water generally include mobile systems and/or methods for removal of mineral hardness and other particulate impurities via lime softening filtration. Chemicals are added to a body of water containing unwanted mineral hardness (or other particulate impurities) and mixed to assist dispersion. The chemicals react with the hardness minerals making them insoluble. The resulting precipitate falls out of solution to the bottom of the body of water for subsequent removal via filtration. This eliminates or otherwise reduces the need for draining water and/or adding new water to a body of water to maintain proper mineral hardness balance and/or concentration of other particulate impurities.
