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.

Abstract: The present invention provides a method for extracting ε-polylysine (ε-PL) and its hydrochloride salt from fermentation broth, which belongs to the field of bio-separation engineering. ε-PL and its hydrochloride salt are produced from fermentation broth through sequential solid-liquid separation, ultrafiltration, two-stage ion exchange, nanofiltration, evaporation concentration and drying techniques. Technologies of membrane filtration and two-stage ion exchange are applied to the preparation of ε-PL and its hydrochloride salt in the present invention, and the invention are characterized by reduced cost, improved automation, and increased product yield and purity, and the method of the present invention would be more suitable for industrial production.

Abstract: A method of producing a scale-control resin including combining in an aqueous solution a cation-exchange resin and a weak-acid anion mineral or salt having a multivalent cation to allow ion exchange between the resin and the multivalent cation. The cation-exchange resin may be a weak-acid ion exchange resin. The method may further include adding a strong-acid salt having the same multivalent cation as the weak-acid anion mineral or salt to the aqueous solution.
