Patent number: 9162910Abstract: A fluid treatment system includes a fluid source, at least one anaerobic reactor vessel, and at least one aerobic reactor vessel. The anaerobic reactor vessel contains retaining a set of retaining structures that are at least partially coated with an anaerobic biofilm. The aerobic reactor vessel contains an aerobic biofilm. When fluid from the fluid source is exposed to the anaerobic biofilm, the anaerobic biofilm removes one or more metal substances from the fluid. When the fluid is exposed to the aerobic biofilm, the aerobic biofilm may cause organic materials in the fluid to metabolize. The system also may include a precipitation reactor that separates divalent metals from the fluid, a settling facility that forms a slurry comprising separated metals, and a neutralization reactor that modifies the fluid to a substantially neutral pH.Type: GrantFiled: July 11, 2012Date of Patent: October 20, 2015Assignee: ALLEGHENY-SINGER RESEARCH INSTITUTEInventors: James Christopher Post, Randy Hiebert, Robert Hyatt

Patent number: 8480902Abstract: A method of prevention of acid rock drainage excludes oxygen from waste rocks that contain ferrous sulfides by building an oxygen bio-barrier over exposed surfaces of the waste rock. The bio-barrier may be formed by applying a slurry to the rock. The slurry may contain several components such as microbial material, one or more nutrients, water or another fluid, and optionally water-absorbent material. The microbial material may include bacteria, algae, fungi or a combination thereof. Additionally, the slurry may contain one or more acid-neutralizing compounds, one or more cellulose-containing substances, and one or more UV protecting agents.Type: GrantFiled: July 2, 2010Date of Patent: July 9, 2013Assignee: Allegheny-Singer Research InstituteInventors: James Christopher Post, Garth David Ehrlich, John William Costerton

Patent number: 8425775Abstract: 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.Type: GrantFiled: June 22, 2010Date of Patent: April 23, 2013Assignee: Allegheny-Singer Research InstituteInventors: James Christopher Post, Garth David Ehrlich, John William Costerton
