A master’s thesis at the College of Engineering at the University of Karbala discussed sulfates, the impact of their high concentrations on the environment, and the method of removing them from water resulting from treatment plants.
The study presented by researcher Ashraf Fakhry Obaid aimed to reduce the concentration of sulfates to what is consistent with the acceptable limits of the World Health Organization, estimated at (250) milligrams per liter of drinking water.
The study concluded that the produced material has a high ability to remove dissolved pollutants, as this was demonstrated in its removal of dissolved sulfates at a rate exceeding (90%).
