Graphical Abstract (IMAGE) National Research Council of Science & Technology Caption The KIST's research team found that magnesium inhibits the formation of CaCO3 and CaSO4 and effectively prevents membrane fouling since the magnesium readily combines with the carbonate and sulfate ions in the seawater The team also found that the added magnesium chloride (MgCl2) increased the stability of the hydrophobic membrane, thereby increasing wetting resistance.
