ABSTRACT:
Treating water with various grades of attapulgite clay and sepiolite using contacting or percolation techniques removes substances not removable by standard water purification methods under many conditions. Substances such as pesticides, toxins, hormones, heavy metal cations and viruses are removed from water by adsorption upon the clay surface. When contacting is employed, the clay containing the adsorbed substances is subsequently removed by sedimentation or filtration. The clays can be regenerated by appropriate chemical or thermal techniques.
