The content is very low. Our company also has an iodine removal process, but since the iodine content in the brine is low, we have not implemented such a process. The same is likely true for bromine as you mentioned
Theoretically, these should all be removed, as these ions affect the ion membrane. However, the iodine and bromine contents in ordinary brines are below the requirements of ion exchange membranes, so there is no need to remove them. But if it is found to exceed the requirements of the ion membrane, it must be removed.
