Demineralization of process water

Also called de-ionization, demineralization means the removal of total dissolved solids (TDS) contained in raw water.

This might be necessary because these minerals may cause problems in downstream applications and water purity levels required.

Demineralization is used for high pressure boilers and numerous other industrial processes.
