University of Delaware researchers have developed an inexpensive, nonchlorine- based technology that can remove harmful microorganisms, including viruses, from drinking water. The patented technology incorporates highly reactive iron in the filtering process to deliver a chemical "knock-out punch" to a host of notorious pathogens, from E. coli to rotavirus.
The new technology could dramatically improve the safety of drinking water around the globe, particularly in developing countries. According to the World Health Organization (WHO), over a billion people lack access to safe water supplies.
