Removal of Fluoride from Groundwater by Batch Electrocoagulation Process Using Al Plate Electrodes

Abstract

Dental fluorosis cases are observed due to the high consumption of high fluoride drinking water in some parts of Anatolia. Fluorosis is resulted from high concentrations of fluoride in groundwater and observed in some regions of Turkey having volcanic rocks and geothermal fields. Results of fluoride analyses showed that the concentrations in groundwater samples were above the admissible limit values for potable water (>1.5 mg/L). Objectives of this work are; to study the high fluoride in groundwater of Sarım-Karataş region, its health effects and to examine its removal efficiency from groundwater by electrocoagulation (EC). EC process including the electrodes, reactor and the power source successfully removed the fluoride from groundwater sample. F removal rate was found as ~96% at the end of 3 hour.
