Abstract: The present study deals with the treatment of distillery wastewater by continuous electrocoagulation (CEC) method utilizing iron (Fe) as an electrode material. Impacts of flow rates (L/h) and retention time (τ) were investigated on reduction of different physicochemical parameters (TS, colour, COD). COD reduction of 80.10% and 83.1%; and color reduction of 83.2% and 91.5%, separately was accomplished at retention time of 2 and 4h. In addition to this, after 200 minutes electrolysis time (ET), 71% of TS in wastewater was diminished at flow rate of 1 L/h. SEC was found to be from 14.1 to 11.6 kWh/kg COD eliminated with change in flow rate from 3 to 1 L/h at 160 minutes ET. Dissolution of electrodes was likewise explored with an alteration of flow rates.
