Innovative method reduces arsenic in drinking water to tough EPA standard
HOBOKEN, N.J. -- A Technogenesis ® Company grown at Stevens Institute of Technology, HydroGlobe Inc, has licensed to Dow Chemical Company a patent-pending technology that effectively removes arsenic III and V from drinking water. Pioneered by Stevens researchers Dr. George P. Korfiatis and Dr. Xiaoguang Meng, the innovative technology will be developed by Dow to create new adsorptive media for cost-effective removal of arsenic and heavy metals from drinking water.
"This technology is the most effective available today for removal of both arsenic and heavy metals from drinking water," said John Schroeder, CEO of HydroGlobe. "We are pleased to be working with Dow to bring the technology to the marketplace."
The titanium-based adsorbent will increase the efficiency of point-of-use and point-of-entry water treatment applications, and will provide value to municipalities who need a safe, cost-effective way to meet the new EPA arsenic standard of 10 ppb that takes effect in 2006. The New Jersey State DEP is also considering the imposition an arsenic standard of less than 10 ppb, which HydroGlobe's technology has been demonstrated to meet.
"Arsenic removal is a high priority issue in today's water treatment marketplace," said Ian Barbour, general manager, Dow Liquid Separations. "This new technology will enable us to make great strides in delivering the highest quality water at the lowest cost, while meeting government regulations." Technogenesis is Stevens' unique environment for education and research, in which students, faculty, and partners in academia, government and industry jointly nurture new technologies and companies from laboratory innovation to marketplace implementation.
ABOUT HYDROGLOBE, INC. (www.hydroglobe.com)
HydroGlobe is a company of scientists, engineers and businesspeople, who are convinced that the prevalence of heavy metals, particularly arsenic, in water poses a serious and continuing threat to human health – and have decided to do something about it.
In 1997 at the Center for Environmental Systems at Stevens Institute of Technology in Hoboken, New Jersey, researchers developed the "Direct Co-precipitation Filtration Process" which they successfully piloted at sites in the United States to remove contaminants such as arsenic, chromium, selenium, copper and lead from groundwater and surface water.
Based on this technology, HydroGlobe was founded in 2001. These same researchers invented a simple, inexpensive family-sized filter. In their first application, they created the first arsenic-free village in Bangladesh, attracting the world's attention to the dire health risk posed to its 70 million people. For that success and others, HydroGlobe was awarded "Most Socially Responsible Company" at the New Jersey Technology Council Venture Fair in 2002. The next year HydroGlobe won the "Best Early Stage Company" award at the same fair.
Recently, HydroGlobe was awarded a contract to demonstrate the effectiveness of its lead removal from leachate in firing range berms.
Today, HydroGlobe, as the sole and exclusive licensee of water technologies from Stevens Institute, has teamed with industry partners to supply products that efficiently and effectively remove heavy metals from water.
