Demineralisation Plant (DM)

DM (demineralised) water plants are systems used to carry out industrial water treatment. To be more precise, the DM plant remove dissolved solids or minerals from process streams and feed water. These plants remove minerals using any one of the following procedures.The demineralization plants are two-column systems, where the water first passes through a cation exchange column and then next passes through an anion exchange column.Demineralization is the process of removing mineral salts from Water by using the ion exchange process. Demineralised Water is Water completely free ( or almost ) of dissolved minerals as a result of one of the following processes.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.
