Demineralized Water - an overview | ScienceDirect Topics

Demineralization (DM) Demineralized water is required particularly for boiler feed purposes. In case where the total dissolved solids (TDS) of the raw water is very high, demineralized (DM) water is used for the cooling tower make–up water. In one variation, DM water is used as the make–up water for the urea plant direct cooling tower (CT).
