Ion Exchange can be defined as a reversible exchange of ions between a solid (resin) and a liquid containing dissolved ions. Mineral salts are comprised of cations and anions. Since deionization requires the removal of all ions, both the negatively charged anions and positively charged cations, minerals capable of attracting both are required. These materials are known as anion and cation exchange resins.
Mixed bed deionizers are fixed bed systems in which ion exchange resins are contained in pressure vessels. The water is then forced through the resin. After a service run, the resin becomes exhausted and unable to remove additional ions so it must be regenerated with strong acid and base solutions to restore its ion exchange capacity..
How Does Mixed Bed Resin Work
Water treatment operators prefer to utilize mixed bed deionization resins in order to refine product water and obtain demineralized water quality. Mixed bed is made up of durable acid cation exchange and strong base anion exchange resin.
More contaminants are exchanged by hydrogen and hydroxyl ions within this process, and the water generated is often exceptionally pure.
