Abstract
A tank for storing a liquid is provided with a circulation passage for circulating the liquid by a suction pump. A pressure at the suction port of the suction pump is maintained at a negative pressure lower than a pressure at which gases dissolved in the liquid and the liquid is circulated, whereby the gases having been dissolved in the liquid are separated and the bubbles entrained by the liquid grow in size. These gases and bubbles are collected, agglomerated and discharged in the line connected to the discharge port of the suction pump.
