SKU: MBDI Category: Ion Exchange Systems > Water Deionizers Brand: Pure Aqua Other Names: Mixed Bed DI System, Stainless Steel MB Ion Exchange Unit, MB Polisher Machine, Mixed Bed De Ionization System


Mixed Bed Deionizers MBDI Series

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.

Pure Aqua 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.
