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 time. However recent technical improvements made in the field of EC has increased its popularity. Recently, electrocoagulation (EC) has been playing more prominent role in the drinking water treatment because it provides some significant advantages such as quite compact, easy operation, automation, no chemical additives, high velocities and reduced amount of sludge. In this paper various electrocoagulation studies conducted for the efficient removal of fluoride from water has been compiled and presented as available in the literature.
