| Abstract |
| An electrochemical treatment has a great efficiency in removal of non-biodegradable material and it has high applicability in wastewater treatment due to a short operating time. Insoluble electrode used in electrochemical water treatment process is mainly manufactured through the platinum metal oxide coating process on the Ti substrate. The purpose of this study using electrochemical treatment with Ti/Ir(Titanium/Iridium) electrode is to provide fundamental data of Soluble Cutting Fluids treatment in CODCr. The result as follows. Experimental data in relation to applied voltage and concentration of NaCl are outlined. Under the condition of no addition of NaCl, changing on applied voltage as 15 V, 20 V, 25 V for 60 mins, the removal rates of CODCr were 57.14%, 75.71% and 71.43%(40 mins) for each voltage. The removal rates of CODCr increased with increasing the applied voltage and these experimental results show that removal rate of CODCr at the each concentration of NaCl increased with increasing the concentration of NaCl. |
