What Is Demineralised Water?
Demineralised water, commonly called DM water, is water that has had dissolved minerals, salts, and ions such as calcium, magnesium, sodium, chloride, sulphates, and nitrates removed through processes like ion exchange, reverse osmosis, or electrodeionization.
Unlike ordinary drinking water, DM water contains extremely low levels of dissolved solids, making it suitable for industrial and scientific applications where impurities can affect product quality or equipment performance.
DM water is widely used in:
- Pharmaceutical manufacturing
- Chemical processing
- Automotive battery production
- Laboratories
- Boiler feed systems
- Power generation
- Cosmetics manufacturing
- Electronics production
Why Choosing the Right Demineralised Water Supplier Matters
