Nanobubble Aeration (NBA)
‘A true game changer’

Nanobubble aeration is an exciting recently developed technology offering several benefits, particularly in water treatment, aquaculture, and environmental management in many sectors.

The use of nanobubbles
-tiny bubbles with diameters smaller than 200 nanometres-
can provide the following advantages:

Improved Oxygen Transfer

Nanobubbles increase the surface area for oxygen transfer in water, leading to higher dissolved oxygen levels. This helps in promoting the health of aquatic organisms in aquaculture systems and enhances biological processes in wastewater treatment.

Enhanced Water Treatment

Nanobubbles can improve the efficiency of processes like coagulation, flocculation, and flotation in water and wastewater treatment, leading to better removal of contaminants such as oils, fats, and heavy metals.

Increased Stability

Nanobubbles tend to remain stable in water for extended periods, sometimes for weeks, unlike traditional microbubbles, which quickly rise and escape. This prolonged stability provides a bank of used gas and ensures longer-lasting effects in water treatments.

Enhanced Disinfection

The bubbles can generate reactive oxygen species (ROS) that act as natural disinfectants, helping to degrade harmful pathogens, bacteria, and viruses in water. Using air, oxygen and even ozone ROS values increase dramatically.

Improved Water Quality in Aquaculture

By boosting oxygen levels and reducing harmful gases (like ammonia), nanobubble aeration improves the water quality in fish farms, supporting better growth and health of fish and other aquatic species.

Energy Efficiency

Nanobubble aeration systems can be more energy-efficient than traditional aeration methods, as they require less power to achieve the same or better oxygen transfer rates.

Reduction of Biofouling

Nanobubbles can help reduce biofilm and scale formation on surfaces in supply or irrigation pipes, tanks, and other equipment, leading to lower maintenance costs and enhanced system efficiency. Nozzle clogs and cleaning down time can be a thing of the past.

Sustainability

The technology is based around enhancing natural aeration processes making it more environmentally friendly, more sustainable and reducing the need for chemicals and other interventions in water treatment processes. It can be used to restore natural water ecosystems.
