Deionised Water Uses 



Deionised water is water that has had almost all of its mineral ions removed, including calcium, sodium, iron, copper and chloride. It is often confused with demineralised water, which is water that has had all of its minerals and contaminants removed. Deionised water is used regularly in laboratory and pharmaceutical environments to prepare chemicals and mixtures or test certain substances for specific compounds.



Its other uses include:




  • In acid and alkaline batteries


  • Flushing and topping up car cooling systems


  • In household detergents


  • In perfumes and other cosmetics.



Although deionised water has had most of its ions removed, it still isn’t cannot be classed as entirely pure. Our demineralisedand ultrapurewaters are recommended alternatives for when higher grade water is required.



Other names for deionised water include DI Water, de-ionised Water and purified water. 



Production & Testing of Deionised Water 



We make deionised water using a several step filter process. We first use an organic trap, where a special resin removes most of the organic matter.  The water then passes through a twin-bed deionizer, where one anionic tank removes the cat ions whilst the other cationic tank removes the An ions.  By now, the maximum level of impurities in the water is 10 µS/cm - already much lower than traditional distilled water. At this point, the water is can be called deionised.



To further reduce impurities, the water is then passed through a mixed bed resin, where impurities are reduced to > 0.05 µS/cm.  The deionized water is given ultraviolet treatment, passing through a strong UV light to kill any remaining micro-organisms.  Finally, the water moves through a 0.2 micron filter.  After the final stage, the water is "Ultrapure water" – this can be purchased from us here.
