Found here:<br /><br />http://www.physorg.com/news6198.html<br /><br />The U.S. Environmental Protection Agency has grappled with the goal of lowering the perchlorate risk, but current solutions are difficult or very expensive. <br /><br />Because perchlorate cannot be removed by conventional water treatment processes, Rittmann, director of the Center for Environmental Biotechnology at the Biodesign Institute at ASU, has developed a new technology that uses bacteria to render perchlorate-contaminated water harmless. <br /><br />“We are really just harnessing the natural capabilities of microorganisms,” says Rittmann, who also is a civil and environmental engineering professor. “What we consider contaminants, they consider food.” <br /><br />The system, called a membrane biofilm reactor (MBfR), uses hydrogen gas as an electron donor to reduce the perchlorate ions to harmless chloride ions (like those found in everyday table salt) and water. <br /> <div class="Discussion_UserSignature"> <p>"1) Give no quarter; 2) Take no prisoners; 3) Sink everything."  Admiral Jackie Fisher</p> </div>
