Abstract
This study aims to investigate removal of methylene blue dye from synthetic wastewater using electrocoagulation method. Two electrocoagulation reactors with a new configuration were used in this study. One of them with aluminum electrodes and the other with iron electrodes. The effects of several parameters such as initial pH, detention time initial concentration, current density, electrode surface area and conductivity on the removal efficiency were studied. Experimental results revealed that the removal efficiency using aluminum and iron electrodes increased with the increase of every parameter stated except for the initial concentration. It was found that the optimum conditions for aluminum and iron electrodes were: initial concentration of 10 mg/L, current density of 4 A/m2, electrode surface area of 1.3 m2, conductivity of 2200 μS/cm and initial pH of 7 and 11 for aluminum and iron electrodes, respectively. The results showed that within 70 min of detention time and at the optimum conditions, the maximum removal efficiency of dye was 93.62 and 97% for aluminum and iron electrodes, respectively. At the optimum conditions, it was found that the energy consumption for dye removal using aluminum and iron electrodes was 0.634 and 0.375 kW.h/m3, respectively.
