Nanobubbles as described above are generated in various ways, such as a swirling liquid flow type, a state mixer type, an ejector type, a venturi type, a pressure dissolution type, an ultrasonic type, an electrolysis type, and a micropore filter type.

In order to generate nanobubbles through various types of nanobubble generating facilities or devices, a liquid (feed water) mixed with gas is supplied, and the gas is converted into microbubbles to generate nanobubbles.

The process in which the feed water is converted into microbubbles is made through a process in which the feedwater containing air bubbles (a mixture of water and air) is separated and compressed while passing through the microtubules of the generating means provided with the microtubules.
