METHOD AND DEVICE FOR FLUORIDE REMOVAL FROM DRINKING WATER

摘要

A water filtration device and method in which water is pumped through a chamber (513) containing iron oxide particles or material (750), which allows removal of ionic contaminants, including fluoride. Water is then pumped through a plurality of ultrafilration tubes (632, 521). The water enters the sides of the tubes into the tube interior and flows out of the open ends of the tubes. The sides and the ends of the tubes are separated by a water impermeable barrier (22).
