20110186508 | MEMBRANE BIOFILM REACTOR FOR REMOVING CONTAMINANTS FROM GROUND WATER - Apparatus and methods for water treatment are described, particularly for the simultaneous removal of nitrate, perchlorate, and other organic contaminates from contaminated water using a membrane biofilm reactor (MBfR). | 08-04-2011 |
20090152194 | REMOVAL OF SELENIUM IN CONTAMINATED WASTEWATER STREAMS - Compositions and methods for the removal of selenium species from water containing high-salt concentrations and/or petroleum contaminants are described. The compositions and methods use a selenium-reducing microorganism adapted to adverse environments. | 06-18-2009 |
20090039031 | Controlling the formation of hexavalent chromium during an oxidative remediation of a contaminated site - A method for inhibiting formation of hexavalent chromium during oxidative remediation of a contaminated site containing trivalent chromium is described. The method comprises introducing ozone at a first point to the contaminated site, where the ozone is introduced at a first frequency and for a first period of time, and introducing hydrogen peroxide to the contaminated site, where the hydrogen peroxide is introduced at a second frequency and for a second period of time. The first and second frequencies and first and second periods of time are selected to inhibit formation of hexavalent chromium within the site of remediation. | 02-12-2009 |
20090032471 | Innovative treatment technologies for reclaimed water - Innovative methods and systems for the removal and destruction of contaminants present in reclaimed or other waste water are described. | 02-05-2009 |
