Demineralised water

Tap water usually contains small amounts of salt. Demineralised water, also called demiwater, is technically pure water that has all salts removed. This makes the water suitable for numerous applications where the use of pure, good quality water is important, for instance the chemical and foodstuffs industries.
Demineralised water can for example be used as rinse water, boiler water, cooling water, test water or battery water.
