Abstract
The present disclosure relates generally to the treatment of water using biochar. More specifically, the treatment of flowback water from drilling operations such as hydraulic fracturing or the treatment of tailing water from tar sands production. Such treatment results in the reduction of various constituents such as metal ions, organic compounds and various metals to provide recycled water suitable for reuse or discharge.
