Electrolytic Defluoridation (EDF) Technique
In India, an estimated 62 million people, including 6 million children suffer from fluorosis due to consumption of excess fluoride contaminated water. As per BIS 10500, 2004 and WHO guideline the desirable limit of fluoride in drinking water is 1.0 mg/L, which can be extended to 1.5 mg/L in the absence of alternate source.
Electrolytic defluoridation process is a water purification system suitable for fluoride affected area with water containing excess fluoride. The defluoridation process is based on the principle of electrolysis, using aluminium plate electrodes placed in the raw water containing excess fluoride. During the electrolysis, anode gets ionized and fluoride is removed by complex formation, adsorption, precipitation, coagulation and settling.
