Portable Exchange Deionization

How Does Deionization Work?

Deionization uses two types of synthetic resins to remove virtually all ionic material from water (99.9%). No other method will achieve 18.3 megohms/cm resistance (the highest purity of low mineral water possible).

Here’s how it works, the Cation resin exchanges positively-charged ions for H+ while Anion resin exchanges negatively-charged ions for OH-. As Cation resins release hydrogen (H+) in exchange for cations (positively-charged ions in water), Anion resins release hydroxide (OH-) ions for anions (negatively-charged ions in water). The displaced H+ and OH- combine to form H2O.

Water Specialties, Inc. has been Utah’s contractor for â€‹Deionized water since 1984.
