FAQ
A nanobubble is an ultra-fine bubble, typically less than 200 nanometres in diameter, that remains suspended in liquid due to its extremely small size. Unlike larger bubbles, nanobubbles have unique properties, including a high surface area-to-volume ratio, stability, and the ability to stay in liquid for an extended period. They are used in various applications, from water treatment to enhancing industrial processes.
Nanobubbles solve several problems across different industries. They enhance oxygen delivery in water, making them valuable for aquaculture and agriculture. In water treatment, they help remove contaminants and improve water quality. Nanobubbles also improve cleaning efficiency in industrial processes and can be used in various applications, including oil and gas production, concrete strength improvement, CO2 reduction, and cooling tower efficiency. Their ability to remain stable in liquids for long periods makes them effective in applications where sustained action is required.
Nanobubbles can last for days, or weeks, in a liquid, depending on the environmental conditions and the medium they are in. Their small size and the negative charge on their surface help them resist coalescence, allowing them to remain suspended in liquids for much longer than larger bubbles.
Nanobubbles improve water quality by enhancing the oxygenation of water, which supports the breakdown of organic matter and promotes the growth of beneficial aerobic bacteria. They also assist in the removal of contaminants like heavy metals, oils, and other pollutants by increasing the efficiency of oxidation processes. Nanobubbles can also help reduce biofilm and algae growth, leading to cleaner and healthier water.
The primary difference between nanobubbles and microbubbles is their size. Nanobubbles are typically less than 200 nanometres in diameter, while microbubbles are larger, usually ranging from 1 to 100 micrometres. Nanobubbles have a longer lifespan and greater stability in liquid due to their small size and negative charge, while microbubbles rise to the surface more quickly and burst.

Nanobubbles enhance oxygen transfer by providing a large surface area relative to their volume, allowing for more efficient oxygen dissolution in water. Their small size enables them to stay suspended in water longer, maximising the contact time with the surrounding liquid and ensuring better oxygen distribution throughout the water column.
Nanobubbles assist in removing pollutants from water through enhanced oxidation and flotation processes. Their small size and large surface area increase the efficiency of chemical reactions, helping to break down and oxidise organic and inorganic contaminants. Additionally, nanobubbles can attach to pollutants, making it easier to separate them from the water through flotation.
Nanobubbles improve the efficiency of chemical reactions by providing a larger surface area for gas-liquid interactions. This increased surface area facilitates faster and more complete reactions, reducing the amount of time and energy required for chemical processes. Nanobubbles can also enhance the effectiveness of catalysts, leading to higher yields and better process efficiency.
