Enhancing quality of life through advanced nanobubble applications across various industries.

What is a nanobubble?

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.

What is a nanobubble used for?

Nanobubbles are used in a wide range of applications due to their unique properties. In water treatment, they are employed to improve water quality; in agriculture, they enhance plant growth; and in aquaculture, they increase oxygen levels in water. Nanobubbles are also utilised in various industrial processes, such as oil and gas production, improving concrete strength, reducing CO2 emissions, and enhancing the efficiency of cooling towers.

Nanobubbles are generally negatively charged because of the adsorption of ions from the surrounding liquid onto their surface. This charge helps stabilise the bubbles by preventing them from coalescing or merging with other bubbles, allowing them to stay in suspension for longer periods. The negative charge also contributes to their unique interactions with contaminants in water, making them effective in water purification processes.

Why are nanobubbles negatively charged?

What problems do nanobubbles solve?

Nanobubbles are formed through various methods, including the rapid mixing of gas into a liquid, electrolysis, or using specialised nanobubble generators. One advanced method is through hydrodynamic cavitation, where gas is introduced into a liquid under high pressure and then rapidly released, creating nanobubbles. Our multi-chamber hydrodynamic cavitation device, the G-CAV, is designed to revolutionise gas infusion processes across various industries. The G-CAV ensures efficient and consistent formation of nanobubbles, making it ideal for applications ranging from water treatment to industrial processes.

What is the difference between nanobubbles and microbubbles?

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.

Nanobubble technology benefits a wide range of industries, including agriculture, aquaculture, wastewater treatment, food and beverage processing, oil and gas production, concrete improvement, CO2 reduction, cooling towers, and industrial cleaning. Each of these industries can leverage nanobubbles for applications like water treatment, enhanced oxygenation, cleaning efficiency, and improved process outcomes.

What industries can benefit from nanobubble technology?

How do nanobubbles improve water quality?

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.

Can nanobubbles be used in wastewater treatment?

Yes, nanobubbles are highly effective in wastewater treatment. They help in breaking down organic pollutants, enhancing biological treatment processes, and reducing sludge formation. The high surface area of nanobubbles allows for more efficient gas transfer, making them ideal for aerating wastewater and improving the overall treatment process.

Nanobubble for Wastewater

Yes, nanobubbles are highly beneficial in aquaculture. They enhance water quality by increasing dissolved oxygen levels, which is crucial for the health and growth of aquatic organisms. Nanobubbles can also help reduce harmful ammonia and nitrite levels, leading to a more stable and healthier environment for fish and other aquatic species.

How do nanobubbles enhance oxygen transfer in water?

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.

How do nanobubbles affect the growth of plants?

Nanobubbles positively affect plant growth by increasing the oxygen levels in the water used for irrigation. This enhanced oxygenation supports better root respiration, leading to more robust root systems and increased nutrient absorption. As a result, plants grow faster, healthier, and are more resistant to diseases.

Nanobubble for Agriculture

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.

What are the energy savings associated with using nanobubbles?

Nanobubble technology can lead to significant energy savings, particularly in processes that require aeration or mixing. Due to their efficient gas transfer properties, nanobubbles can reduce the need for mechanical aeration, which is typically energy-intensive. This efficiency translates into lower energy consumption and operating costs.
