Cleaning water purification system

摘要

The present invention relates to the provision of water having a conductivity of 3 ¼S/cm or less, comprising prefiltering (2) inlet water for removal of particulate solids, pumping the prefiltered water and subjecting it to deionization by reverse osmosis (5) and ion exchange (6) treatment. The deionized water is collected in an air-free tank (7) from which the water having a conductivity of 3 ¼S/cm or less may be obtained.
