Ion Exchanger

Ion exchangers are used to remove salts (cations and anions) from the water.

The applications are:

• Softening - Removal of Calcium (Ca) and Magnesium (Mg) ions

• Demineralisation - Removal of a part or all ions from water

• Treatment of radioactive waste water

• Removal of NH4⁺ from waste water

• Selective cation ion-exchange for the removal of heavy metals

• Principle
• Methods of regeneration
• Ion exchange vocabulary
• Ion Exchange reaction

For every different application of water conditioning specific ion exchange resins (Rohm & Haas / Bayer / Purolite) are available. Lenntech can advise you which is most appropriate. Also we can supply several ion resins for retrofitting in existing ion exchanger units. Furthermore we can calculate for every existing system and water quality if it is worthwhile to install a reverse osmosis system as pre-treatment or as replacement. Please feel free to contact us for any information on this matter.
