Abstract
wastewater of textile industry, especially azo compounds often are contain toxic materials and persistent in the environmental. Therefore, it is necessary to evaluate performance various methods for the removal. Acid red 37 combinations is single structure in the azo dyes which have already been widely used in the textile industry. Purpose this study Optimization of effective factors and Investigation performance electrofenton and electrocoagulation method at synthetic wastewater for Acid Red 37 dye removal from aqueous. This study, synthetic wastewater was formation from Acid Red 37 dye and pilot Scale was implemented. In this study was investigated concentration, pH, electrical density and temperature parameters. Ultimately was determine optimum conditions. was determine Amount of consumption energy at 90 percent efficiency. To investigate degradation of pollutant was GC-Mass. results was show both of methods was ability removal of Acid Red 37. But electrocoagulation was beter than electro fenton. Respectively, Optimum conditions to removal electro fenton and electrocoagulation were pH=3, time=120 min, density- 30 mA.cm2, concentration=50 mg/L, consumption energy 142.8 KWh/Kg Dye and pH=7 time=120 min, density- 30 mA.cm2, concentration=150 mg/L, consumption energy 130.2 KWh/Kg Dye. the results was show electrocoagulation beter than electrofenton and high ability for removal Acid Red 37.
