The University of Illinois at Chicago School of Public Health has launched a solar-powered ozone-based water treatment project in Kisumu, Kenya, as part of a project funded by Grand Challenges Explorations, an initiative of the Bill & Melinda Gates Foundation. Dr. Samuel Dorevitch, associate professor at the UIC School of Public Health, principal investigator on the grant, traveled to Kenya this summer to study the expansion and testing of this clean drinking water system in two informal urban settlements located in the city of 500,000 people.
The water disinfection system uses solar power to produce ozone gas. The gas is then bubbled through water collected from natural or municipal sources to kill germs and make the water safe for drinking. In partnership with the Safe Water and acquired immune deficiency syndrome (AIDS), or SWAP, a non-governmental organization based in Western Kenya, Dr. Dorevitch and colleagues have already installed small versions of the system in ten homes in Kisumu’s Kisian Village, where it can disinfect about 40 liters of water a day.
“New and better ways of treating drinking water have to work well in the laboratory, but they also have to be user-friendly and work well in people’s homes,” says Dr. Dorevitch, who is also a fellow of UIC’s Institute for Environmental Science and Policy. “People in Kisian Village who used the solar-powered water treatment system say it’s simple to use and they continue to use it even months after the research ended.”Friday Letter Submission, Publish on January 10
