CHARLOTTESVILLE, Va. (AP) - A water purification tablet that could enhance the quality of life for millions of people in developing countries is making its official debut at the University of Virginia.
Called MadiDrop, the ceramic tablet can disinfect water for up to six months when it is placed in a vessel from which water is poured.
The disk was developed by PureMadi, a nonprofit U.Va. organization. Madi is a South African word for water. The filtering process has been used for the past year in Limpopo province in South Africa, where a factory has produced several hundred flowerpot-like water filters.
Each filter can serve a family of five or six for two to five years. Developers of the tablet say it removes or kills 99.9 percent of pathogens in water.
