Isi artikel

UV/H2O2 reactor was operated to decolourize an azo dye (Cl reactive Red 195A) from textile wastewater. In the present study, the UV radiation source was a low-pressure mercury arc lamp (60W emitting at 253.7nm). The effects of initial hydrogen peroxide dosage and UV irradiation were examined to evaluate the process applicability, an estimation of the main operating costs, in particular the electric power for UV irradiation and the H2O2 addition. In general, the result demonstrates that the UV irradiation time had a major influence on the overall treatment cost and therefore had to be kept to a minimum. To achieve the required colour removal efficiency, increased addition of H2O2 was required.
