pH. The fluoride removal is directly related to aluminum F− hydroxide complex [AlnFm(OH)3n−m] formation during electrocoagulation (Emamjomeh et al. 2011).
2.6 Conclusion and Future Perspective
The contamination of fluoride in drinking water and groundwater has reached an alarming level already. This needs the immediate concern and involvement of people to alleviate this problem. Suitable remedial measures should be explored, meeting the geohydrological, sociocultural, ecopolitical, and environmental aspects of the area and also the people. Several defluoridation techniques have been employed when the level of fluoride increases in potable water. The fluoride concentration limit of potable water for any region is based on its dietary habits, annual daily temperature, nature, and level of exposure in the area. The remediation technology should consider the facts of availability of material, cost‐effectiveness, and level of fluoride removal, as well as technical complexity.
