Water De-ionizer (Double Bed)
Model LP047
Water De-ionizer (Double Bed) Deionizers (DI) remove both cations and anions, releasing hydrogen ions (H+) in exchange for the former, and hydroxyl ions (OH-) for the latter. The hydrogen a hydroxyl ions subsequently combine to form pure water. In this process the raw water is first passed through Cation resin. By this process the all the ionized salts get converted to acids. This acidic water is then passed through anion resin which absorbs the acid. Thus the output water gets de-mineralized.
Applications:
Deionizers are most commonly used when ionic contamination is such that reverse osmosis alone cannot be relied upon to produce water of acceptable quality. In such most instances, mixed bed deionizers may be placed downstream of the reverse osmosis unit, completing the purification process.A wide variety of public water vending machines as well as many industrial applications in the electronics industry operate in this manner.
