DuPont says it will install a large-scale PGClear plant at its Louisville, Kentucky, facility in June to treat groundwater contaminated with chloroform.
The installation is part of a full-scale PGClear field trial being conducted by 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 contaminants. It uses a combination of palladium and gold metal to break down dangerous compounds such as vinyl chloride, trichloroethene, also known as TCE, and chloroform into non-toxic byproducts.
The 6-by-8-foot DuPont plant contains valves and pipes that carry Saudi Arabia Mobile Number List groundwater to a series of tubes, each containing thousands of beads of palladium-gold catalyst. The granules, about the size of a grain of rice, trigger a chemical reaction that breaks down chloroform into non-toxic methane and a chloride salt.
The technology emerged from basic science research at Rice during a 10-year federally funded initiative to use nanotechnology to clean up the environment.
According to Michael Wong, Rice professor of chemical and biomolecular engineering and lead investigator of the PGClear project, chlorinated compounds have been widely used as solvents for many decades and are common groundwater contaminants around the world. These compounds are also extremely difficult to treat inexpensively using traditional technologies, the researchers said.
Solving the problems of this technology began at the nanoscale. Rice's team was working with nanoscale catalysts when they developed the technology that eventually became PGClear. The technology was subsequently scaled up so that it could be used in traditional reaction systems for on-site implementation.
Wong has been working on this project since 2001. DuPont contacted Wong about his award-winning research in 2007 and proposed developing a scalable process using palladium-gold catalysts to treat other chlorinated pollutants such as chloroform and vinyl chloride.
In March, an Environmental Protection Agency report alleged that Google employees were exposed to high doses of cancer-causing TCE at one of the company's satellite campuses at the Superfund toxic waste site.
Between mid-November and mid-January, after workers turned off part of the air ventilation system at an office complex in Mountain View, California, TCE levels at two Google office buildings exceeded concentrations considered safe by the Environmental Protection Agency, according to an EPA report. . federal agency obtained by the Center for Investigative Reporting.
