In this work, the performance of batch electrocoagulation (EC) treatment using iron electrodes with monopolar and bipolar electrode configurations for trivalent chromium (Cr (III)) removal from a synthetic wastewater was investigated. The influences of current density (from 2 to 25 mA/cm2) and initial metal concentration (from 100 to 250 mg/L) on the removal efficiency were explored in a batch stirred cell for monopolar and bipolar configurations. Removal of Cr (III) by EC process from aqueous solution with both monopolar and bipolar electrode configurations was a feasible process. For the initial Cr (III) concentration of 250 mg/L, almost complete removal (99.88%) of Cr (III) was noted after 20 min of EC in case of bipolar electrode arrangement at 25 mA/cm2 with 4.5 mmol/L of supporting electrolyte (Na2SO4) against 89.58% of Cr (III) removal for monopole electrode configuration. At the same electrolysis time, the power consumption was 47 and 15.3 kWh/m3 in case of monopolar and bipolar configuration respectively for the previous removal conditions.
