Abstract
In this study, titanium scraps were used as bipolar packed-bed electrodes for the electrochemical treatment of soluble cutting fluid (SCF), and the removal efficiency of COD<sub>Cr</sub> from the SCF and oil from the titanium scraps were analyzed in accordance with the scrap density, current density, electrolyte type and concentration. The removal efficiency of COD<sub>Cr</sub> after 60 min was 76.0%, 73.8%, 85.0%, and 84.2% for a scrap density of 0, 10, 20, and 30 g/L, respectively, while the removal efficiency for oil was 75.8%, 78.8%, and 66.8% for a scrap density of 10, 20, and 30 g/L, respectively. In addition, the removal efficiency of COD<sub>Cr</sub> after 60 min was 85.0%, 89.1%, and 94.4% and that of oil was 78.8%, 86.3%, and 89.3% for a current density 40, 60, and 80 A/m<sup>2</sup>, respectively. Finally, after testing the system with no electrolyte or with either Na<sub>2</sub>SO<sub>4</sub> or NaCl (5-10 mM), the highest removal efficiency of COD<sub>Cr</sub> and oil was 94.4%, and 89.3%, respectively, with no electrolyte and a current density of 80 A/m<sup>2</sup>. In conclusion, the removal of efficiency of COD<sub>Cr</sub> and oil was maximized with a scrap density of 20 g/L, a current density of 80 A/m<sup>2</sup>, and no electrolyte.
