What is De-ionised water?

Deionisation simply means the removal of ions.

Ions are electrically charged atoms or molecules found in water that have either a net negative or positive charge. For many applications that use water as a rinse or ingredient, these ions are considered impurities and must be removed from the water.

Ions with a positive charge are called “Cations” and ions with a negative charge are called “Anions”. Ion exchange resins are used to exchange non desirable cations and anions with hydrogen and hydroxyl, respectively, forming pure water (H20), which is not an ion. Below is a list of ions commonly found in municipal water.

Where can you use de-ionised water?

  • To prepare chemical solutions and mixtures
  • For preparation of electrolytes for the acid and alkaline batteries
  • For dilution of concentrated anti-freeze
  • For final rinse of printed circuit boards, for washing equipment from acids and alkalis, after technological operations in the electronics industry.
  • For refueling cars glass washers
  • For top up the cooling system, because it does not create salt deposits in the system
  • For flushing cooling systems of cars
  • In the perfume industry
  • To fill irons and steam household devices and where is necessary to avoid mineral deposits

Using deionised water as a cleanser is a new method. It does not use any chemicals; they are replaced by the water. The water is brought to almost perfect purity. This deionised water is four times cleaner than distilled water. It is already in the so-called active phase, when decomposed into ions and cations, it itself easily removes everything that is on the cleaning surface. As a result on the surface of any material washed with deionised water after drying there are no spots.

The de-ionised water is not for drinking because it doesn’t contain any salts and trace elements.
