What is an ultrafine bubble generator?

An ultrafine bubble generator is a device that mixes water and a gas and produces ultrafine bubbles. Ultrafine bubbles should be smaller than 200 nano meter to be called an ultrafine bubble. Since 200 nano meters is quite large to be called nanoscopic the name nanobubbles is for this reason not officially used by ISO. The ISO has named nano sized bubbles ultrafine bubbles. The naming convention follows the same names as for particles.
Basically, there are two types of ultrafine bubble generators, first there are gas-water circulation types of ultrafine bubble generators. Second there is a gas-water pressurization-decompression also often referred to as pressurized dissolution type of ultrafine bubble 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 ultrafine bubbles. 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 too low to create any ultrafine bubbles.
Acniti sells ultrafine bubble generators with the gas-water circulation type, we have branded them the turbiti series. Acniti also sells the pressurized dissolution ultrafine bubble generators, which are branded as GaLF. GaLF stands for Gas Liquid Foam.
