[/top_collection] [bottom_collection] The Deionization Process The vast majority of dissolved impurities in modern water supplies are ions such as calcium, sodium, chlorides, and iron. Using a deionized water system for laboratory water, these ions can be removed through a technique called ion exchange. Positively charged ions (cations) and negatively charged ions (anions) are exchanged for hydrogen (H+) and hydroxyl (OH-) ions, respectively, due to the resin's greater affinity for other ions. The ion exchange process occurs on the binding sites of the resin beads. Once depleted of exchange capacity, the resin bed is regenerated with concentrated acid and caustic, which strips away accumulated ions through physical displacement, leaving hydrogen or hydroxyl ions in their place.

Deionizer Types There are four basic forms of deionizers: 1.Disposable cartridges 2.Portable exchange tanks 3.Automatic units 4.Continuous units A two-bed system employs separate cation and anion resin beds, while mixed-bed deionizers for high purity water use both resins in the same vessel. The highest quality water is produced by mixed-bed deionizers, while two-bed deionizers have a larger capacity. Continuous deionizers, mainly used in labs for polishing, do not require regeneration. High Quality and Low Prices US Water focuses on disposable DI cartridges, which provide the highest quality water at the lowest price,
