A University of Virginia nonprofit is unveiling a new invention that will improve water quality for over three billion people in developing countries. Tuesday, PureMadi officially debuts its ceramic water purification tablet, called a MadiDrop.
The disk, made of clay, sawdust, water and either silver or copper, can disinfect water for up to six months.
"All you do is take the tablet and drop it in a water storage container and it works for about six months to purify your water. So it's very simple to use, very inexpensive to make, so we think it could have a very positive impact on the developing world water," said Jim Smith, PureMadi director.
PureMadi is currently collaborating with a cooperative of almost 50 women potters in the Limpopo province of South Africa. The nonprofit is teaching them how to produce and sell these tablets.
