The challenge of improving water quality in water-stressed areas of the world may have a natural champion in the Moringa oleifera tree. More specifically, a particular protein found in the meal of dried and ground M. oleifera seeds, when adsorbed onto sand, has shown some excellent preliminary results in removing total suspended solids (TSS) and in killing coliform bacteria.
