description PROBLEM TO BE SOLVED: To provide an apparatus which can efficiently separate an oil-containing alkali solution from an alkali solution used for washing away oil which is an object to be treated, and enables the separation at a relatively low cost. SOLUTION: One tank 1 storing a foamed oil-containing alkali solution is installed (case A), or a plurality of tanks, such as a primary tank and a secondary tank, are installed together (case B). In the case A, a disposer 2 for eliminating bubbles in the foamed oil-containing alkali solution in the tank 1 and changing them into droplets or a liquid phase and discharging them or it outside the tank 1 is installed in the tank 1, or the same disposer 2 and a bubble generator 5 are installed. In the case B, the same disposer 2 and bubble generator 5 are installed, and a pipe 44 extending from the disposer 2 in the preceding tank for discharging treated liquid is connected to the following tank.
