Abstract
Devices and associated methods described herein in accordance with embodiments of the present technology can, for example, treat acidity and remove suspended solids and heavy metals from acid mine and acid rock drainage, as well as from other acidic and various aqueous fluids of various pH. The disclosed system includes a cavitation/electro-coagulation reaction chamber, solids separation, and other optional components including a passive media contact reaction chamber, and/or an oxidation/reduction electrode assembly to facilitate or expand upon parameters requiring treatment. The disclosed system can be packaged in small housing units suitable for insertion within mine tunnels or adits, but may also be expanded for large scale applications.
