In areas where acid mine drainage has diminished the available water supplies, processes which are capable of producing potable water from this drainage are of interest. Ion exchange processes have this capability. The investigation was intended to study several conventional ion exchange processes, using commercially available materials and to determine if any of these processes could be used to produce potable water from acid mine drainage. The three best systems were found to be: Strong acid cation exchanger regenerated with sulfuric acid; Weak base anion exchanger regenerated with caustic soda; and Weak base anion exchanger regenerated with sodium hydroxide and carbon dioxide (modified Desal process). Treatment plants in three sizes were designed for each system so that cost estimates could be established.
