Abstract
A method of in situ treatment of fracture fluid that is contaminated with a heavy metal may include passing a flow of contaminated fracture fluid through a reactor vessel. The reactor vessel may contain a plurality of biofilm retaining structures. Each of the structures may at least be partially coated with a biofilm. Additionally, the biofilm may include a plurality of bacteria retained in a matrix and the matrix may include DNA, protein and carbohydrates produced by the bacteria.
