In general, nanobubbles are ultra-fine bubbles that cannot be seen by the eye, and are microscopic air particles with a size of 1/2,000 of a normal bubble and less than 25 μm of skin pores. When extinct, 1) 40KHz of ultrasonic waves are generated, and 2) It generates a high sound pressure of 140db, and 3) instantaneous high heat of 4,000 to 6,000 degrees is generated.

In other words, general air bubbles rise in water and rupture at the surface, but nanobubbles are reduced by pressure in water, generating various energy and extinguishing.

These nanobubbles are mainly generated when water and air are violently rotated with ultra-fine bubbles.

Such nanobubbles are used in various fields due to their physical and chemical properties such as "gas dissolution effect, self-pressurization effect, charging effect", and in recent years, especially in the fields of fishing and agriculture, they are used for various aquaculture and hydroponic cultivation. In the medical field, it is used for precise diagnosis, and it is used in physical therapy, high-purity water treatment, and environmental devices in various fields.
