“…According to the other investigators, EC can be used for treatment of boron‐polluted water and wastewater containing boron at initial concentrations of more than 50 mg L −1 . However, it is seen that the removal efficiency of EC is higher at the lower concentrations of 50 mg L −1 in the right optimization conditions.…”

“…The different properties exhibited by the various metal or nonmetal compounds make it possible to use many of the boron compounds in the industry . Boron is also found in surface water at around 4.5 mg L −1 . The long‐term use of water containing boron can cause toxic effects for plants, animals, and humans .…”

The objective of this study is to determine the optimum parameters of electrocoagulation process in treatment of boron in low concentrations. Especially, studies on electrode optimization in low boron concentrated waters are insufficient. Therefore, the effect of electrode combination (Al–Al, Al–Fe, Al–SS, Fe–Al, Fe–Fe, and Fe–SS), pH (5–9), current density (8–24 mA cm −2 ), distance (1–3 cm), and electrolysis time (10–90 min) on treatment of boron containing wastewater is studied to obtain maximum removal efficiency. The maximum removal efficiency of boron is obtained as 95.6%. Operation conditions for maximum removal are the electrode combination of Fe–Al, current density of 16 mA cm −2 , pH 7.0, concentration of 30 mg L −1 and the reaction time of 70 min. Operating cost of the electrocoagulation process is calculated as 2.35 $ m −3 . This study indicates that the electrocoagulation process can be successfully applied in order to treat boron‐polluted wastewaters at low initial concentrations.
