Ion Exchange Plants

Lenntech can design, build and commission tailor-made and turnkey ion exchange (IX) plants, covering several flows.

Please check Reference projects for more information on Lenntech built and running plants.

Ion exchange can have several applications, such as water softening (removal of calcium and magnesium ions), demineralization, as polishing step after Reverse osmosis, and for removal of heavy metals.

For more information regarding these applications check our product sheets:

- Softeners - Removal of Calcium (Ca) and Magnesium (Mg)

- Cationic/Anionic demineralisation plants

- Mixed Bed Polishing plants

- Selective ion-exchange for the removal of heavy metals

Lenntech can supply several ion resins for retrofitting in existing ion exchanger units.

Check the available exchange resins: Dowex / Rohm & Haas / Lanxess / Purolite.

We can also calculate for you existing system and water quality whether it is cost-effective to install a reverse osmosis system as pre-treatment or as replacement.
