Abstract
The liquid treating method according to the present invention introduces a bubble into liquid phase and applies vibration waves, such as ultrasonic waves, from each sides of the bubble. Collision of the vibration waves with the bubble imparts the compression pressure to the bubble. This effect is used to dissolve a gas forming the bubble into the liquid phase or to improve liquid quality of this liquid phase.
