De-mineralized Water

De-mineralized water is specially purified water that has had most or all of its mineral and salt ions removed, such as Calcium, Magnesium, Sodium, Chloride, Sulphate, Nitrate and Bicarbonate. It is also known as Deionised water, DI or Demin water. De-mineralized water and deionised water are generally considered distinct from distilled water, which is purified in a still ie. by boiling and re-condensing, a process which also removes salt ions. The major differences are that De-mineralized water is usually freer of mineral ions, depending on the number of processes used to make it, and distilled water may have less organic contaminants, as deionisation does not remove uncharged molecules such as viruses or bacteria. However, deion sation also leaves behind less 'scale' than distillation, and so has a cleaner production. De-mineralized water is water completely free (or almost) of dissolved minerals as a result of one of the following processes:

  • Distillation
  • De-ionization
  • Membrane Filtration (reverse osmosis or nanofiltration)
  • Electrodyalisis
  • or other technologies.

The amount of dissolved solids in water that has followed one of these processes could be as low as 1 mg/I and is in any case always less than 10 mg/I. The electrical conductivity is generally less than 2 mS/m and may be even lower (< 0,1 ms/cm).


  • It can be used as Battery Water.
  • It can be used as Bus/Truck/Motor Car Radiator Water.
  • It can be used as Generator Jacket Water.
  • For Pharmaceutical use.
  • For Pathological use.
  • For Certain Production use etc.
