boiler softening ion exchange resin principle

Water Softeners | Pretreatment Solutions | ChemTreat Inc.

In a water softener ion exchange occurs as the water runs through a bed of small plastic resin beads saturated with sodium ions. As the water containing calcium and magnesium ions flows past the resin beads calcium and magnesium ions stick to the ion exchange resin liberating the sodium ions which then go into the solution.

Ion Exchange (IX) - DuPont

Ion exchange is the reversible interchange of ions between a solution with soluble ionized substances and a solid (the ion exchange material such as a cation resin) in which there is no permanent change in the structure of the solid.

Anion vs. Cation | Ion Exchange Resins | Dealkalization

Ion exchange resins are made up of a highly porous polymeric material that is acid base and water insoluble. The tiny beads that make up these resins are derived from hydrocarbon and are about ½ millimeter in diameter. There are two main types of resins used for ion exchange: anion and cation.Within these two types there are four main classifications of ion exchange resins:

Chapter 08- Ion Exchange Water Demineralization & Resin ...

Sodium zeolite softening is the most widely applied use of ion exchange. In zeolite softening water containing scale-forming ions such as calcium and magnesium passes through a resin bed containing SAC resin in the sodium form. In the resin the hardness ions are exchanged with the sodium and the sodium diffuses into the bulk water solution.
