Abstract
In India, fluoride is the major inorganic pollutant of natural origin found in groundwater. Fluoride pollution occurs due to natural and manmade reasons and high concentrations have a detrimental effect on health. Electrochemical techniques like Electrocoagulation(EC) appears to be one of the most effective approaches for treatment of water and wastewater because of its versatility, safety, selectivity, amenability to automation and environmental compatibility. Results show that the percentage removal of fluoride was around 94 to 96% for monopolar and bipolar electrodes. Adsorbents like tricalcium phosphate and activated alumina used along with electrocoagulation process also gave promising results. 2013 CAFET-INNOVA TECHNICAL SOCIETY.
