An Overview of the Deionization of Water

The deionization of water process is what happens when salt is removed from the water. For this process, the water passes through an ion exchange material, which removes the salt completely. Ion exchange is reversible and happens between liquids and solids without change to the solids. The primary salts found in water include sodium chloride, magnesium sulfate, and calcium bicarbonate, all of which are removed by deionization.

Deionization of water can sometimes be called demineralisation, and both mean the same thing. Removing salt from the bones is primarily when demineralisation or desalinisation is used. Primarily, people convert sea water to fresh water using desalinisation so that it can be used for drinking and other purposes.

Ion exchange resins stay in the pressure tank, so water must pass through the resins to be deionized. After some time, resins are completely exhausted, which means they no longer work and you need to replace them. Usually, sulphuric or hydrochloric acid is used to restore resin, and sodium hydroxide can regenerate anion resins.


When you consider deionization, it ensures that the water produced is of a higher quality than distillation or regular tap water. Along with such, you can find deionisers of various sizes, which means you can choose one that provides you with enough water to bathe, drink, do laundry, and more.

No dangerous chemical waste is produced using the process, which means it is safe for any household or business. Along with such, many heavy metals can be removed from your drinking water using this technology.


As with most things in life, there are some disadvantages to deionization. The efficiency of the process is increased when using mineral water, so you may want to use that instead, which can be a disadvantage if your property doesn’t produce mineral water.
