Nanobubbles in Aquaculture 


OXYGEN

The intensive nature of aquaculture systems can lead to a number of environmental and operational challenges, one of which is oxygen deprivation.

In aquaculture systems, the high density of organisms and the presence of organic matter such as feces and uneaten food can lead to an increase in dissolved organic matter (DOM) and a decrease in oxygen levels in the water. This can lead to a number of negative effects on the health and growth of aquatic organisms, including reduced growth rate, increased susceptibility to disease, and increased mortality.

In addition to these negative effects on the organisms being farmed, oxygen deprivation in aquaculture systems can also lead to environmental problems such as eutrophication and fish kills. Eutrophication is the process by which an ecosystem becomes overloaded with nutrients and organic matter, leading to excessive growth of algae and other aquatic plants. This can deplete oxygen levels in the water and lead to the death of fish and other aquatic organisms.

To mitigate these problems, aquaculture systems often rely on mechanical aeration or oxygen injection systems to supplement the oxygen levels in the water. However, these methods can be costly, energy-intensive, and can lead to the production of harmful by-products such as ozone. Therefore, there is a need for alternative methods for oxygenation in aquaculture systems that are more efficient and environmentally friendly. Nanobubbles to the rescue!

NANOBUBBLES OXYGEN

Oxygen nanobubbles are tiny bubbles of oxygen gas that measure between 20 and 200 nanometers in diameter. As water pushes through a nano injector, oxygen is ported into the water train. As the oxygen and water collide it creates cavitation. These cavitation bubbles collapse and generate very small bubbles, called nanobubbles, that remain suspended in the liquid. When the liquid contains dissolved oxygen, the nanobubbles formed will be oxygen nanobubbles.

The small size of the nanobubbles makes them highly stable and long-lasting, allowing them to remain suspended in the water for extended periods of time. This is in contrast to traditional oxygenation methods, which typically rely on large bubbles that quickly rise to the surface and escape into the atmosphere.

Oxygen nanobubbles have a high surface area-to-volume ratio, which allows them to dissolve large amounts of oxygen into the water. This makes them an efficient and effective way to supplement the oxygen levels in aquaculture systems and other water-based systems.

Oxygen nanobubbles also have the potential to reduce oxygen consumption in aquaculture systems. In traditional oxygenation methods, oxygen is released into the water in the form of large bubbles, which quickly rise to the surface and escape into the atmosphere. This results in a significant amount of oxygen being lost, which leads to higher oxygen consumption.

However, because oxygen nanobubbles are small and stable, they do not rise to the surface as quickly as large bubbles do. This allows for a more prolonged and efficient release of oxygen into the water, resulting in less oxygen being lost to the atmosphere. Additionally, the high oxygen concentration provided by the nanobubbles could also mean that less oxygen is needed to maintain the desired levels.

In summary, oxygen nanobubbles can increase oxygenation efficiency by providing a higher oxygen concentration, and reducing oxygen consumption by reducing the amount of oxygen lost to the atmosphere.
