Ion exchange resins for water treatment by adsorption
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. Water treatment is the best-known and biggest field of application for ion exchange resins.

US5166220A - Water softening process - Google Patents
An improved process for regenerating the ion exchange resin in a water softening system. The process substantially reduces the amount of water and salt required for regeneration of the resin. The process includes the steps of venting the resin tank to the atmosphere and draining eventually all of the water from around the resin. Next, a brine solution is added to the resin tank.

Ion-exchange Resin | Ionic Systems USA
Ion exchange occurs in a variety of substances and it has been used on an industrial basis since circa 1910 with the introduction of water softening using natural and later, synthetic zeolites. Sulfonated coal, developed for industrial water treatment, was the first ion exchange material that was stable at low pH.
