Ion Exchange Resins

Ion Exchange Resins

Ion exchange (IX) resins are polymers that are capable of exchanging ions with ions in a solution that is passed through them.

Ion exchange resins are used to remove dissolved particles from liquids. Therefore, functional groups are bonded to the polymer beads. These functionalized polymers adsorb particular anions or cations from the liquid and discharge others.

While membrane technology is very cost-efficient for water with a high salt content, only ion exchange resins can purify water with low salt concentrations to the point where only trace amounts remain.
