System and method for generating nanobubbles

Abstract

Provided is a nanobubble generating system and a nanobubble generating method in which nanobubbles exist stably in a liquid phase by a very simple constitution and a very simple process. A nanobubble generating system has a generation chamber for accommodating a gas phase part existing in the upper side and a liquid phase part in contact with the lower side of the gas phase part under sealed condition, a supersaturated dissolved liquid generating device for generating supersaturated dissolved liquid in which a gas is dissolved in the liquid phase part under supersaturated condition, and a nanobubble generating device for feeding a pressurized gas to said supersaturated dissolved liquid via through-holes having a nano-sized opening size to generate nanobubbles having a diameter smaller than 1 μm.
