Abstract

The aim of study was designed to investigate removal of dye (reactive scarlet) by electrocoagulation using tubular iron electrodes. Experiments were conducted to examine the effects of the operating parameters, such as pH, current density and flow rate on dye and COD removal in the electrocoagulation process. The energy consumptions were also analyzed. COD of the wastewater was reduced from 620.4 to 21.5 mg/L with the removal efficiency of 96.5 % at the current density of 30 mA/cm2, supporting electrolyte concentration of 0.1 M Na2SO4, and flow rate of 200 mL/min. The high dye removal efficiencies were obtained at all experiments. The initial dye concentration of 200 mg/L was reduced to 1.08 mg/L with the removal efficiency of 99.4 % at 30mA/cm2 after 90 min electrocoagulation.
