Abstract

This study examined the possibility to remove color causing-compounds from effluent by pulse electrocoagulation. For better result, this work is focused on the comparison of energy saving effect at different current density, pulse frequencies. During the pulse electrocoagulation experiment using sacrificial aluminium electrodes operated at an electrical potential of 30 V. A factorial design was applied for optimization of working conditions of the pulse electrocoagulation experiments. In all tested cases, a decrease of the color removal time was observed with the increase of current density, it depends very much upon the pulse frequency. The energy consumption during electrocoagulation process were also discussed. The results indicated that the optimum conditions for the treatment of dyeing wastewater were achieved at temperature:25 , and inter-electrode distance:5 cm, voltage is 30V, the initial PH is about 8,pulse frequency is 1000Hz,Operating time is 20min.Finally, the technical-economical analysis results have clearly shown that the pulse electrocoagulation method is very promising for dyeing wastewater treatment.
