WebIon exchange operation is basically discontinuous: a loading phase, called service run, is followed by regeneration of the exhausted resins. There are two main methods for the regeneration process: Co-flow regeneration, where the fluids are flowing from the top to the bottom of the column both during the service run as well as during regeneration. WebIon exchange is a method widely used in household filters to produce soft water for the benefit of laundry detergents, soaps, and water heaters. This is accomplished by exchanging divalent cations (such as calcium Ca 2+ and magnesium Mg 2+) with highly soluble monovalent cations (e.g., Na + or H +) (see water softening ).

Ion exchange takes place in one column, while the resin in the second column is being regenerated, resulting in continuous operation. Usage Examples. Continuous ion exchangers are used when it is imperative that the product be continually generated.

WebThe principle of the ion exchange process is the trading of different ions or complexes on a resin/sorbent bed, triggered by the different affinity (selectivity) of the resin to each one of the ions. A typical resin is a water insoluble polymer cross-linked matrix with a functional group. The exchanging ions from the treated solution are bonded ...
