Clean Water of All Impurities

We have both separate and mixed bed deionization systems so that you can find the right one for your needs.

Deionization is a method of water purification that removes mineral salt contaminants. Calcium, copper, iron and sodium ions, as well as anions such as bromide and chloride, are removed during the purification process. Deionization is a method used when clean water is required immediately due to the rapid degradation of highly pure water.

In ion-exchange resin tanks, negative and positive molecules in water are exchanged with hydrogen (positive) and hydroxyl (negative) molecules to purify potentially polluted water. Filtration effectively removes organic contaminants, improving water quality and reducing scale formation. In addition, the resins bind to any mineral salts in the liquid, separating them from the water and allowing only pure water to exit the tank. As a result, deionized water is a commonly used solution in manufacturing facilities.

Because the degree of purification provided by deionization tanks varies depending on the resin and the deionization technique employed, it is crucial to select the right one for each application.

Separate-Bed Deionization Systems

In this system, separate columns of cation and anion resins are used. This streamlines the resin regeneration process. Because one resin’s regenerant will completely load the regenerant for the other, they must be kept separate. For example, the cation resin must be regenerated with a strong acid. Strong acid would fill all of the anion resin’s sites, leaving no sites for ion exchange with the ions we’re attempting to eliminate. After regeneration, the resin can remove impurities from the water, leaving you with highly pure water.

Mixed-Bed Deionization Systems

While using separate anion and cation resin beds produces relatively pure water, residual products from the two exchange processes contaminate it. The combination of the two resins purifies the water even further. The resins must, however, be separated for the regeneration process. This is accomplished by combining two different densities of resin and then allowing the lighter resin to float to the top using a controlled water flow. A mixed-bed Diffusion Ionization system can generate one order of magnitude purer water than a two-bed Diffusion Ionization system.
