Water Engineering Technologies offers demineralization systems for a wide range of applications. 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 is chosen very accordingly to the volumes and composition of the raw water, the effluent- quality require for different uses and the comparative capital and operation cost. If silica removal is not required, 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.
