Demineralisation or Deionisation is the process of removing mineral salts from water by using the ion exchange process.
Demineralised water is water almost free of dissolved minerals as a result of one of the
following processes:
- Distillation
- Deionization
- Membrane filtration (reverse osmosis or nano filtration)
- Electro dialisis
- Or other technologies.
Demineralized water also known as Deionized water which has its mineral ions removed. Mineral ions such as cations of sodium, calcium, iron, copper, etc and anions such as chloride, sulphate, nitrate, etc are common ions present in water.
