What is Micro Nano Bubble?

Micro nano bubble is the general terms for micro-bubble, micro nano bubble and nano bubble. Micro bubble is very the bubble of which diameter is several tens of micrometer (1µm = 1/1,000mm). The diameter or bubble visible to the naked eye is approximately 2mm. but the micro bubble of which size is less than its 1/1,000 is invisible the naked eye because its particle is too fine.

Size and Features of Micro Nano Bubble

Bubble Type Per Size and Its Features

Type	Definition and Features
Normal Bubble	Bubble diameter more than several tens µm Rising fast above the surface of water and bursting No quality change and no energy source
Micro Bubble (NB)	Fine bubble of its diameter 10µm (1/100mm) ~ several tens µm Slow rising toward the surface of water Complete dissolution with contraction and disappearance in water (supply of oxygen particle in bubble) - increasing possibility of oxidation related to sterilization and cleaning Energy emission with forming super high pressure and temperature at disappearance.
Micro Nano Bubble (MNB)	Fine bubble of its diameter 0.1µm (1/10,000mm) ~ 10µm Slow rising toward the surface of water Contraction speed faster than micro bubble Generating by contraction of micro bubble
Nano Bubble (NB)	Ultra fine bubble of its diameter less than 0.1µm (1/100000mm) Short bubble life due to self-pressurization of the surface tension Possibility of repulsive electrostatic force by surface electrification or long time Stabilization by surface-active agent (Usable as nano oxygen water or nano ozone water Especially stabulizad nano bubble by the surface electrification maintains bubble character for long time, so that it can be applied to biotechnological and medical fields
