Abstract
The electrocoagulation was applied to removal of fluoride and coexisting anions from simulated groundwater. The concentration of fluoride, chloride and sulfate was of 5 ppm, 347 ppm and 199 ppm, respectively. The influence of pH, current density, electrolysis time and sulfate presence were studied. Fluoride and sulfate removal efficiency, chloride concentration and specific energy consumption were calculated.
