ACID REGENERATION OF ION EXCHANGE RESINS FOR INDUSTRIAL APPLICATIONS

摘要

Methods and systems for acid regeneration of ion exchange resins are disclosed. Acid resins designed for use in a variety of cleaning application using a water source use a treated, softened, acidic water source according to the invention. Various methods of using the softened acidic water generated by acid regenerate-able ion exchange resins are disclosed to beneficially reduce spotting, filming and scale buildup on treated surfaces, reduce and/or eliminate the need for polymers, threshold reagents and/or rinse aids, and using protons generated in the acidic water effluent for triggering events useful in various cleaning applications.

主权项

1. A system employing an ion exchange resin regenerated by an acid comprising:
an inlet for providing a water source; a water treatment reservoir; a water treatment component housed within the water treatment reservoir, wherein said water treatment component comprises at least one ion exchange resin capable of generating a treated water source by exchanging protons on said resin for dissolved cations including water hardness ions and total dissolved solids in said water source, and wherein said ion exchange resin is an acid form or in an inert metal form; an outlet; and a water delivery line in fluid communication with a cleaning application and/or storage reservoir to provide the treated water source to the cleaning application and/or storage reservoir; wherein the inlet is in fluid communication with the water treatment reservoir; wherein a first end of the outlet is in fluid communication with the water treatment reservoir and a second end is in fluid communication with the water delivery line; wherein the treated water source is a softened, acidic, and low total dissolved solids (TDS) water having a hardness level of less than about 2 grains and a pH less than about 6.
