WebElectrodeionization ( EDI) is a water treatment technology that uses DC Power, ion exchange membranes, and ion exchange resin to deionize water. EDI is usually a polishing treatment to reverse osmosis (RO). EDI differs from other RO polishing technologies such as chemically regenerated mixed beds, in that it is continuous and requires no ... 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 ).
