Publication number: 20080185335Abstract: A method and apparatus for remediating a failing wastewater treatment system comprising a positive air, oxygen, ozone, or combination thereof, generating pressure pump (40) directing the air, oxygen, ozone or combination through a tube (50) to an air stone (60) suspended in the effluent. Attached growth bacteria grow on a plurality or random directional brushes (116) in an effluent tank, e.g., septic tank (14).Type: ApplicationFiled: May 19, 2005Publication date: August 7, 2008Inventor: Karl K. Holt

Publication number: 20080185337Abstract: A method for degrading, detackifying and reducing solvent in water comprising organic solvent-laden water-borne paint that comprises adding to the water an effective degrading, detackifying and/or solvent-reducing amount of at least one microorganism culture and sufficient micronutrients to sustain the growth of the at least one microorgansim culture and to reduce solvent content of the water. A method of reducing chemical oxygen demand in water comprising organic solvent-laden water-borne paint, wherein the water contains an excess amount of organic solvent from one or both of paint spray operations and paint spray nozzle cleaning operations, the method comprising adding to the water an effective degrading and detackifying amount of at least one microorganism culture and micronutrients to sustain the growth of the at least one microorgansim culture, whereby chemical oxygen demand in the water is reduced by at least 50% relative to the same system without adding the micronutrients.Type: ApplicationFiled: January 29, 2008Publication date: August 7, 2008Inventors: Amer Almadidy, Natacha Lavayssierre

Patent number: 7407581Abstract: Improved systems and methods for removing the load of perchlorate and other oxyanions off of ion exchange resins through bioregeneration are disclosed. The improved systems and methods rely upon direct contact between the resin and a liquid product containing enrichment cultures of or pure strains of perchlorate-destroying microorganisms. Controlled temperatures also lead to improvements as do upflow conditions leading to bed expansion. These methods can be incorporated into methods for removing perchlorate from aqueous streams.Type: GrantFiled: May 11, 2007Date of Patent: August 5, 2008Assignee: Basin Water, Inc.Inventor: Jacimaria R. Batista

Patent number: 7384556Abstract: Systems and methods for co-enhancing contaminant degradation such as LNAPL and DNAPL degradation. Embodiments of the inventive technology may relate to assuring adequate amounts (e.g., concentrations) of certain substances (e.g., nitrogen, electron acceptor, bacteria, microbial substrate) so that degradation of LNAPL and DNAPL is enhanced as intended. Any of the inventive methods may involve the amendment of groundwater with one or more particular substance (uric acid, electron acceptors, microbial substrate, as but a few examples) in order to enhance DNAPL, and perhaps also, LNAPL degradation.Type: GrantFiled: July 19, 2006Date of Patent: June 10, 2008Assignee: The University of Wyoming Research CorporationInventors: Song Jin, Paul H. Fallgren

Patent number: 7341664Abstract: A method and system for forming an in situ subsurface filter in a contaminated aquifer and for removing contaminants from groundwater drawn from a contaminated aquifer. The filter is produced in situ by injecting an aqueous solution comprising bacteria-stimulating chemical components through a well to bioactively generate a subsurface mineral filtering zone surrounding the well. As water is subsequently drawn through the well, contaminants are removed from the water as it passes through the filtering zone.Type: GrantFiled: June 10, 2004Date of Patent: March 11, 2008Assignee: Auburn UniversityInventors: Ming-Kuo Lee, James A. Saunders, Samuel H. Nichols, III
