Present study deals with the treatment of highly polluted dibrominated wastewater (DWW) using electrocoagulation process. The study methodology utilized 2 L batch reactor with four parallel aluminum (Al) electrodes with varying electrode gaps, current density and pH. The results show optimum value of 1.5 cm for electrode gap, 50 Amp/m2 forcurrent density and pH 9. For these optimal valus, the removal efficiencies emerged as: 34.09 % for COD, 29.80 % for TDS, 56.17 % for color and 20 % for turbidity. At pH 9, the maximum total metal loss (TML) was 1.77 g/L, while the highest power consumption was 2.4 Wh/L at pH 3. While pH 3 exhibited the most efficient settling rate, pH 9 resulted in maximum residue and foam weight of 8.42 g/L. Further, electrodes and residue were characterized using SEM, EDX, XRD and FTIR techniques. Investigation given detail information about applicapability of EC process to treat DWW. Results demonstrated that EC process is well applicable to treat DWW.
