Removal of fluoride from drinking water by using electrocoagulation (EC) with aluminium (Al) electrodes

Author(s): Pramod Kharmale, Sangramsingh Thakur
Abstract: Endemic fluorosis caused by fluoride in excess is a global geochemical disease. Maintaining fluoride concentration of 1mg/L in the dietary intake can prevent skeletal and dental problems (WHO, 1.5 mg/L max. limit). Recent attention of scientists has been devoted to the study of different types of low cost methods such as Electro coagulation (EC) is an emerging water treatment technology that has been applied successfully to treat various wastewaters and also for drinking water. Effects of different operating conditions such as pH, voltage, hydraulic retention time (HRT) and number of aluminum plates between anode and cathode plates on removal efficiency are investigated. A simple setup was fabricated made up of Acrylic for Electro coagulation along with sand filter has been used for fluoride removal. The fluoride laden synthetic water is passed through a reactor (1.5 L) in which electro coagulation (current passed 25 amp. to 80 amp.) is done and then effluent was filtered through sand filter and effluent after filtered was analyzed for different pH, Voltage, fluoride concentration. Results showed that there will be significantly reduction of fluoride concentration within time period of 30 to 40 minutes as specified by Indian Standard for drinking water. The objective of the present study is to examine the feasibility of using EC in fluoride removal from drinking water.
