Abstract:
Novel water softening products and methods of treating hard water are provided. The products comprise a salt and a metal chelating agent. The products are useful for regenerating ion exchange material in a water softening system and providing softened water containing both sodium and potassium ions, while having dramatically increased efficiencies over prior art products.
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.

It also relates to a method for regulating the acidity of motor oil whereby the oil is caused to pass through the acidity-regulating device according to the invention. The invention further relates to a vehicle provided with anacidity-regulating device for motor oil according to the invention.
Abstract:
Disclosed is a process that uses reverse osmosis (RO) or nanofiltration (NF) membranes and ion exchange (IX) water softening resins to maximize the production of drinking water, purified industrial service water or recycled purified municipal or industrial effluents. The membrane and ion exchange units are configured in a manner that enables operation of the system at high permeate recoveries in the range 90% to 99%, thus producing purified drinking water with a minimum volume of wastewater to drains and a very low membrane cleaning or membrane replacement frequency. The process mitigates membrane fouling and scale formation and minimizes the use of water treatment chemicals including acidic and alkali solutions and sodium chloride salt that is normally required to regenerate the IX resin. The process provides considerable improvement over "Whole Home RO" drinking water prior art, where the membrane permeate recovery is normally limited to the range 30% - 50%, by producing drinking water more efficiently and in a cost-effective manner.

Abstract:
A water treatment device and method for treating a quantity of water is powered by gravitational flow. The device includes an upper collecting chamber (14) and a filtration chamber (18). The filtration chamber includes a set of reactance containing at least three components wherein one of the components is a polycation and another one of the components is a polyanion. As the weak base polymer, the biological polymer chitosan is preferably used. The method includes subjecting the water to gravitational flow through the filtration chamber (18).
Abstract:
Methods for removal of positively charged microbicidal compound, in particular an aziridino compound, from composition such as a blood product by contacting the composition with a cation exchange resin allowing the positively charged compound to bind to the resin and then separating the resin-bound compound from the composition.
