Abstract
A method for removing sulfates from seawater by immersing a barium adsorbent into produced water to adsorb the barium ions from the produced water. The adsorbent is combined with an acidic solution that pulls the barium ions into the acidic solution. The acidic solution containing barium ions is combined with seawater to precipitate the sulfate as barium sulfate (BaSO).
