Abstract
The optimal operation conditions, including voltage applied, reaction time, distance between electrodes. and electrode material. were investigated for the treatment of soil flushing effluent using electrofloatation. When 3V was applied for 1 hour, 88% oil-water separation efficiency was achieved. In case of 6V and above, 90% efficiencies were achieved. As reaction time and distance between electrodes were longer, separation efficiencies were higher and lower, respectively. Separation efficiencies for different anode materials were copper > aluminum > iron > titanium. It might result from the differences of their electrical conductivities.
