Application of Continuous Electrocoagulation Process for Distillery Wastewater Treatment

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.
