What does water deionization mean in practice?
Ion exchangers remove charged components, but do not effectively retain all neutral substances, particles and microorganisms.
When does it matter?
The mixed bed resin depletes quickly when fed with high mineralization water, so it usually works as post-RO polishing.
Which solutions are related to it?
The output conductivity or resistivity is controlled and the media is replaced or regenerated before process requirements are exceeded.
