| ion exchange |
Most common ion exchange systems use a zeolite resin bed and simply replace unwanted ions (Ca 2+ and Mg 2+ ) with benign (soap friendly) sodium or potassium ions. This is the common water softener. A more rigorous type of ion exchange swaps hydrogen (H + ) ions for unwanted cations and hydroxide (OH - ) ions for unwanted anions. The result is H + + OH - --> H 2 O. This system is recharged with hydrochloric acid and sodium hydroxide. The result is essentially deionized water.
