Nanobubbles are extremely small gas bubbles that can provide a unique way to increase and maintain dissolved gas in water. Unlike conventional bubbles that quickly rise to the surface and escape, nanobubbles can remain suspended in water for extended periods.
How Do Nanobubbles Work?
Nanobubble technology uses shear forces generated at the interface between an object and its surrounding area to break gas, such as oxygen, into nano-sized bubbles.
The smaller bubble size increases the interaction between the gas and water, helping increase the amount of dissolved gas in the water.
Why Are Nanobubbles Different?
One of the key characteristics of nanobubbles is their ability to remain in water without rapidly degassing. This allows dissolved gas to be maintained at a higher level for longer periods compared with conventional larger bubbles.
From Gas to Nanobubbles
The process can be simplified into three steps:
1. Gas Introduction
Gas such as oxygen is introduced into the water.
2. Nano-Sizing
Shear forces split the gas into extremely small, nano-sized bubbles.
3. Longer-Term Dissolved Gas
The nanobubbles remain in the water, helping maintain elevated dissolved gas levels over time.
The Potential of Nanobubble Technology
Because nanobubbles can enhance and maintain dissolved gas in water, the technology has potential applications across areas such as aquaculture, agriculture, water treatment, and other water-based processes.
Nanobubbles may be small in size, but their ability to interact with water makes them an important technology for improving gas transfer and dissolved gas management.
