摘要： A water purification module includes a fluid path and a control unit. The flow path includes a cationic resin cartridge, an anionic resin cartridge in fluid communication with the cationic resin cartridge, and at least one bypass fluid path arranged to bypass one of the cationic resin cartridge and the anionic resin cartridge, while allowing water to flow to the other of the cationic resin cartridge and the anionic resin cartridge. The flow path also includes a valve arrangement comprising one or more valves configured to selectively direct water to the at least one bypass fluid path. The control unit is configured to control the valve arrangement to direct water to the at least one bypass fluid path based on a production mode of the water purification module.

摘要： A system and method configured to restore ion exchange kinetic properties and purify resin is described. Degraded ion exchange kinetic properties of anion resin will eventually result in impurity slippage through resin charges. This system and method employs an acid catalyst in combination with sulfite cleaning solution to remove organic material and to protonate iron oxides for deconstruction and removal from anion resins. The cleaning solution, when applied via a cleaning vessel utilizing an eductor(s)/plenum and wedge-wire screen draw chamber, while controlling all phases of cleaning by electronic monitoring, yields complete restoration of ion exchange kinetics on usable resin. As such, the system and method provides a safe, effective, and vastly improved method for restoring anion resin kinetics and improving regeneration quality, for improved resin performance and minimizing resin replacement costs.

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.

摘要： A method of acid manufacturing using acid cation resins for recycling salt and/or salt products from wastes and/or waste waters utilizes a brine solution, an acid cation resin, an acid solution, and an ion exchanger. The acid cation resin is into hydrogen form with the acid solution within the ion exchanger. The acid cation resin is then washed using water with salinity to remove any excess acid from the exterior of the acid cation resin. A selected brine of salts is then prepared of the desired acid(s) to be produced. The desired acid is produced by contacting the acid cation resin containing cations in concentration with the selected brine. A second ion exchange reaction is executed to substitute hydrogen for cations in the selected brine.

摘要： A method of acid manufacturing using ion exchange resin allows for the production of acids on location where the acid is being utilized to prevent the necessity of transporting the acid. An ion exchange medium provides a medium for substituting hydrogen ions for salt cations within a salt solution in order to protonate the salt solution. As the salt solution becomes protonated to form an acid solution from the respective salt anion as the concentration of hydrogen increases. The ion exchange medium is recharged with a hydrogen ion source solution. The ion exchange resin is safe to transport even while charged with hydrogen ions.
