The issue of barium chloride consumption in the sulfate removal process using the barium method
Thread Content
This post was last edited by sunjl1981 on 2013-1-6 at 20:28. What is the theoretical amount of barium chloride required to remove sulfate ions using the barium method? In the desalinated brine produced using 100,000 tons of ion-exchange membranes, the sulfate content is between 9 and 10 g. The quality of the raw salt used is also poor, which results in a sulfate content of around 9 g in the initial brine. Currently, barium chloride is being used at a rate of 300 kg per hour, but this still doesn’t manage to reduce the sulfate level. Does anyone have any knowledge or experience in this area that they could share? Thank you. ， ， -

If the sodium sulfate level is less than 8g, then the sulfate level should be less than 5.4 for the quality to be considered satisfactory. Therefore, the amount of barium chloride is still insufficient – more needs to be added
Is the original poster still using the barium chloride method to remove sulfate ions? Has it been switched to CIM membrane-based cryogenic denitration?
