Mitigation of Fluoride Contamination from Drinking Water through Fluoride Removal Techniques: A Review

Review of fluoride removal from drinking water.

Fluoride in drinking water has a profound effect on teeth and bones. Up to a small level (1-1.5mg/L) this strengthens the enamel. Concentrations in the range of 1.5-4 mg/L result in dental fluorosis whereas with prolonged exposure at still higher fluoride concentrations (4-10mg/L) dental fluorosis progresses to skeletal fluorosis. High fluoride concentrations in groundwater, up to more than 30 ...

Use of bauxite from active Iranian mines for the removal of fluoride from drinking water

Background: Fluoride plays an important role in bone and dentin mineralization; however, excess fluoride intake is harmful to mankind. Methods: This study evaluated the performance of bauxite from active Iranian mines in removing fluoride from drinking water. The effects of pH, contact time, adsorbent dose, and fluoride concentration on defluoridation and removal efficiency were determined. Ki...

Electrocoagulation: Promising Technology for Removal of Fluoride from Drinking Water - A Review

Electrocoagulation has a long history as a water treatment technology having been employed to remove a wide range of pollutants. Inspite of its manifold applications the technique has never been accepted as a mainstream water treatment technology due to lack of a systematic approach to electrocoagulation reactor design, operation and the issue related to electrode dissolution over period of tim...

Human Health Effects of Drinking Water Fluoride Contamination: Indian Scenario

Fluoride is one of the main contaminants in groundwater present naturally in many parts of the globe causing a set of human health symptoms known commonly as Fluorosis. India lies in the geographical belt with 225 districts of 19 States having high fluoride concentrations (> 1.5 mg/l) in groundwater. For many rural as well as urban areas in India, hand-pumps and tube-wells are the only source o...
