Abstract:
Methods and systems for an integrated acid regeneration of ion exchange resins are disclosed for use in cleaning applications. Acid resins designed for use in a variety of cleaning application using a treated, softened, acidic water source are disclosed. Various methods of using the softened acidic water generated by acid regenerate-able ion exchange resins within a cleaning application, e.g. ware wash machine, 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.
