A useful definition is given below – “The vast majority of dissolved impurities in modern water supplies are ions such as calcium, sodium, chlorides, etc. The deionization process removes ions from water via 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.” 

Usage in the late twentieth century has been varied and numerous – although mainly in the field of industrial usage. From medical, laboratory, pharmaceutical, cosmetics, electronics manufacturing, food processing, plating, countless industrial processes, and even the final rinse at the local car wash, deionized water is even used in our warehouse to maintain water levels in the batteries of our forklift. For most basic usages both distilled and deionized can be seen as fairly interchangeable waters. During the process of distilling water many of the ions are removed.
