Abstract
The prolonged consumption of excess fluoride by people and animals causes a disease called fluorosis. The sources of intake are water, food and air. Over the past seven decades, engineering attempts to tackle fluorosis have focused on defluoridation or removal of excess fluoride from drinking water. A combined process based on coagulation using alum and adsorption/ion exchange using activated alumina is described along with some of the limitations and unsolved problems.
