De Mineralized water treatment plant (D.M. PLANT)

Process :
Demineralization systems are very widely employed not only for conditioning water for high pressure boilers but also for conditioning various process and rinse water the ion exchange system chosen very accordingly to the volumes and composition of the raw waters, the effluent- quality require for different uses and the comparative capital and operation cost briefly if silica removal is not require the system may consist of a hydrogen cation exchanger unit and a weekly basic anion exchanger unit usually followed by a degasifier to remove by aeration most of the carbon dioxide formed from the bicarbonates in the first step when silica removal basic anion exchanger unit usually with a degasifier between the unit to removed carbon dioxide ahead of the strongly basic anion exchanger unit for uses where the very highest quality of effluent is required this may be followed by secondary polishing unit consisting of either.
