PROBLEM TO BE SOLVED: To provide a separation, removal, and circulation system for bubbles in a liquid which makes it possible to efficiently remove bubbles generated in a liquid.SOLUTION: A system is configured by installing a bubble separation apparatus 50 for separating a first oil free from bubbles and a second oil containing bubbles from an oil flowing in from a main tank 10 by utilizing swirling current of the oil and a sub-tank 60 having a plurality of partitioning plates and a plurality of filters for tapping and gathering the bubbles contained in the second oil which flows in. The oil in the main tank 10 is pressurized by a pump 40 and supplied to the bubble separation apparatus 50 via a first pipe P1; the first oil separated by the bubble separation apparatus 50 is turned back to the main tank 10 via a second pipe P2; the second oil is led to the sub-tank 60 via a third pipe P3; and a third oil from which bubbles are removed in the sub-tank 60 is turned back to the main tank 10 via a fourth pipe P4. |
