충진복극전해조를 이용한 수용성절삭유 처리 = Treatment of Water Soluble Metalworking Fluids using Packed Bed Bipolar Electrolytic Reactor

다국어 초록 (Multilingual Abstract)

The treatment of water soluble metalworking fluids has been an important environmental issue in recent years due to the extensive use of oil in the metalworking and metal industries, such as vehicle manufacturing industry. Biological treatment and reverse osmosis (RO) technologies have been used to treat water soluble metalworking fluids, but these conventional methods are ineffective in removing organics, T-N, limiting its use for water quality and economic feasibility. One promising alternative is electrochemical process. To attempt to remove contaminants in metalworking fluid by using an electrochemical method. The effects of the packing volume percentage of packing materials, voltage and electrode distance on the process performance were studied. PBBER were formed and applied voltage per packing materials, electrode separation, and removal efficiency and quantity of electricity per concentration were examined. The summary of the examined results are as below. The removal efficiency of CODCr, Oil & Grease and T-N by PBBER showed that 89.6%, 93.5% and 61.9%, respectively and at the highest with 75% of GAC packed, 7 V, 10 mm electrode distance.
