nanobubble generator

A nanobubble generator or as it should be called according the ISO standards, an ultrafine bubble generator is a device that mixes water and a gas and produces nanobubbles. Nanobubbles should be smaller than 200 nano meter to be called a nanobubble. Since 200 nano meters is quite large to be called nanoscopic the name nanobubbles is not completely appropriate. For this reason, the ISO has named a nanobubble an ultrafine bubble. The naming convention follows the same names as for particles.

Basically, there are two types of nanobubble generators, first there are gas-water circulation types of nanobubble generators. Second there is a gas-water pressurization-decompression also often referred to as pressurized dissolution type of nanobubble generator. All units are based on one principle or the other, or a combination of both. In the gas-water circulation type the gas is introduced into a water vortex and the gas bubbles are formed by breaking the vortex. In the pressurized dissolution method, about 5% of gas is under pressure dissolved in water and forms a supersaturated solution. When the water is depressurized, the gas escapes from the water and forms nanobubbles. It's like opening a bottle of beer or a can of coke, the drink in the bottle is depressurized and bubbles are formed. The pressure in a beer or coke is to low to form any nanobubbles.

Acniti sells nanobubble generators with the gas-water circulation type, we have branded them the turbiti series. Acniti also sells the pressurized dissolution nanobubble generators, which are branded as GaLF. GaLF stands for Gas Liquid Foam.
