The present study is based on removal efficiency of electrode during the treatment of oily wastewater in the samples of industrial origin in the Surajpur region of Chhattisgarh state through electrocoagulation method. The statistical analysis shows that all the variables set in the preparation of the model, within the tested boundaries, have significant effect on the model. Current density, initial pH, and operating time for the treatment of wastewater influence the COD, TOC, and turbidity removal efficiencies. The optimal electrocoagulation conditions for maximum removal efficiencies of COD, TOC, and turbidity found by RSM are illustrated as current density (64.28 A/m2 ), initial pH (7.03), and operating time of EC (20.60 min) for Fe electrode and current density (62.67 A/m2 ), initial pH (5.01), and operating time of EC (24.39 min) for Al electrode. It is characterized by desirability of 0.728 for Fe electrode and 0.819 for Al electrode. At optimized conditions, the actual COD, TOC, and turbidity removals are found to be 93.0%, 83.0%, and 99.8% for Fe electrode and 93.5%, 85.2%, and 99.9% for Al electrode, respectively, which confirms close to the predicted response using RSM. Minimal operating costs for Fe and Al electrodes are 0.371 and 0.337 €/m3. A mathematical approach is useful for picturing the theoretical electrocoagulation of metal cutting wastewater treatment.
