Removal of Water Supply Contaminants: Barium

Barium is very similar to calcium in its chemical behavior. Therefore, processes which are effective in removing calcium should effectively reduce the barium level in water. A. Ion Exchange Ion exchange softening will effectively remove barium from water. The barium, along with calcium and magnesium, will exchange with the sodium ions of the resin.

Impact of polymer EOR and salinity on barium sulphate ...
