Abstract
In this work, a real effluent discharged by Brazilian textile industry, has been electrochemically treated using boron doped diamond (BDD) anode for removing chemical oxygen demand (COD) and colour. Preliminary experiments were performed under real discharged effluent conditions (pH, conductivity and COD) in order to verify the applicability of this treatment process. However, a partial elimination of COD and colour effluent were achieved, 12% and 21%, respectively. Therefore, new set of experiments were carried out where COD of textile effluent was completely reduced by applying 60 mA cm-2 in presence of Na2SO4 and NaCl; reducing the time of depuration and consequently, the costs, confirming the potential efficiency of this dyestuff treatment.
