چکیده انگلیسی
The paper presents the study of electrocoagulation (EC) of aqueous dye solutions of two different industrial dyes in a batch stirred cell. Experiments were carried out with 200Â mg/l individual concentration of methylene blue (MB) and eosin yellowish (EY) in presence of NaCl as electrolyte. Effect of operating time and current density on the decolorization of dye solutions, reduction of chemical oxygen demand (COD) and variation in conductivity, pH during treatment has been studied. Small difference between color diminution and COD reduction has been found with the progress of treatment. First-order rate equation for dye removal has been developed from the experimental results. Sludge formation during EC and problems associated with this solid waste generation and disposal has been assessed. Energy consumption in KWh/m3 with reduction of COD (kg) during treatment has been reported. Electric power consumption of 1.5Â KWh reduces 0.21 and 0.11Â kg COD from 0.24 and 0.14Â kg of initial COD for MB and EY, respectively, starting from 200Â mg/l dye concentration.
