DuPont said it will install a large PGClear plant at its Louisville , Kentucky , plant in June to treat chloroform- contaminated groundwater.
The device is part of a comprehensive PGClear field trial underway at Rice University, DuPont Central Research Center and Stanford University . Researchers say PPGClear can gently but quickly destroy some of the world's most common and problematic pollutants . It uses a combination of palladium and gold metals to break down hazardous compounds such as vinyl chloride , trichlorethylene ( also known as TCE ) and chloroform into non -toxic by-products.
According to the 6-by-8 -foot DuPont device package , groundwater is piped into a series of tubes, each containing thousands of palladium catalyst beads. The particles , about the size of a grain of rice, trigger a chemical reaction that breaks down chloroform into nontoxic methane and chloride salts.
The technology grew out of basic scientific research in a 10 - year federally funded initiative at Rice University to use nanotechnology to clean up the environment.
Michael Wong , professor of chemical and biomolecular Telegram Number Data engineering at Rice University and principal investigator of the PGClear project , said chlorinated compounds have been widely used as solvents for decades and are common groundwater contaminants around the world . These compounds are also extremely difficult to process cheaply using traditional techniques , the researchers say.
Solving the problems of this technology starts at the nanoscale . Rice 's team was working on nanoscale catalysts when developing the technology that eventually became PGClear . The technology was subsequently scaled up so that it could be implemented in the field in conventional reaction systems.
Wong has been working on this project since 2001 . DuPont contacted Wong in 2007 about his award-winning research and proposed developing a scalable process using a palladium catalyst to treat other chlorinated contaminants such as chloroform and vinyl chloride.
In March , an Environmental Protection Agency report said Google employees were exposed to high doses of cancer-causing TCEs at one of the company's satellite campuses located at a Superfund toxic waste site.
According to the U.S. Environmental Protection Agency , two Google office buildings suffered severe damage after workers shut down part of the ventilation system at an office building in Mountain View, California , between mid- November and mid -January . The TCE levels exceed concentrations considered safe by the Environmental Protection Agency . Report . . Federal agency obtained by the Center for Investigative Reporting.
