摘要

This paper presents the results of the treatment of a real textile wastewater by electrocoagulation (EC)process. The textile effluent used in the experiments was obtained from a textile industry inMalatya/Turkey. The effluent was wastewater taken from dying process of the industry. Aluminumelectrodes were connected to an EC reactor in three different types: monopolar-parallel (MP-P),monopolar-serial (MP-S), and bipolar-parallel (BP-P). Color and turbidity removals were selected asperformance criteria. Moreover, the financial cost of the total treatment has been considered asimportant as removal efficiencies. Electrical and sacrificial electrode costs have been used in thecalculation of the total cost. The results show that MP-P mode is the most cost effective for bothelectrode connection types. All connection types show similar results in reducing color and turbidity,MP-P is preferred as a low cost treatment. In addition, iron and aluminum electrode materials havebeen investigated in the MP-P EC reactor. The results show that, according to electrical and sacrificialelectrode costs, iron is superior to aluminum but aluminum electrode leads to high turbidity, color andCOD removal efficiencies.
