Abstract
The present invention includes an anion exchange method that uses sulfate-containing acid mine drainage (AMD), or any sulfate containing water resource, to remove strontium, barium, and/or radium from contaminated water sources, such as but not limited to hydraulic fracturing waste water, flowback, and/or produced water, without requiring any external regenerant. The removal process may be adopted with any waste water or impaired water source containing sulfate anions.
