Sandra McSurdy, U.S. Department of Energy (DOE), ”Treating Flowback Water with Acid Mine Drainage (AMD) for Reuse in Shale Gas Activities”
Researchers at the University of Pittsburgh and the U. S. DOE are developing a treatment for flowback water utilizing AMD. Treating and reusing flowback water on-site will reduce the amount of freshwater needed and the amount of wastewater that needs to be hauled by truck. Sulfate removal tests were performed on flowback and AMD water mixtures with a goal to achieve a final sulfate concentration of less than 100 mg/L for reuse.
