What does demineralization medium mean in practice?
The cation exchanger and anion exchanger can work separately or as a mixture, removing ions up to the limit determined by the capacity and the breakthrough point.
When does it matter?
In water with high TDS, consumption is quick, and the medium does not constitute an independent barrier to microorganisms and organics.
Which solutions are related to it?
Typically, they are fed with RO permeate, conductivity is monitored, and replacement or regeneration is selected to suit the process requirements.
