Nanobubble Technology
Put Oxygen to Work in Your Water Application
Solari Water and Energy uses nanobubble technology to engineer how oxygen and other gases are transferred into water — supporting better water quality, stronger biological processes and improved performance across agriculture, aquaculture, waterways and industrial applications.
Oxygen Changes
What Water Can Do
Water may be available, but that doesn’t mean it is performing at its best.
In biological and production systems, dissolved oxygen can influence conditions around roots, aquatic environments and other oxygen-dependent processes. When oxygen becomes limited, it can constrain the environment the water is supporting.
Nanobubble technology provides a way to engineer oxygen delivery into the water itself, helping maintain oxygen where it is needed rather than relying solely on conventional aeration.
Better Conditions for Biological Processes
Maintaining oxygen availability can support aerobic conditions in root zones, growing systems, aquaculture and other biological water applications, helping create a more stable environment for biological activity and performance.
More Effective Gas Transfer
Ultrafine bubbles remain dispersed in water differently from larger conventional bubbles, helping transfer and retain gases within the water for longer and improving their availability throughout the treatment or production system.
Small Bubbles. Different Behaviour.
Nanobubbles are extremely small gas bubbles that behave differently in water from the larger bubbles produced by conventional aeration. Their size allows them to remain dispersed through the water rather than quickly rising to the surface and escaping.
This creates greater opportunity for oxygen or other gases to transfer into the water, making nanobubble technology particularly useful where efficient and sustained gas delivery is important.
Remain in the Water
Their extremely small size allows nanobubbles to remain dispersed through the water rather than rapidly rising and escaping at the surface.
Increase Gas–Water Contact
Longer residence within the water creates more opportunity for the introduced gas to interact with and transfer into the surrounding water.
Deliver Oxygen Where It Matters
Nanobubbles can carry oxygen through irrigation, aquaculture and treatment systems, helping maintain availability closer to where it is required.
Where Nanobubbles Make a Difference
Nanobubble technology can be applied across very different water environments, from irrigation and livestock production to aquaculture, waterways and treatment systems. The opportunity is the same: put gases such as oxygen to work more effectively in the water, where they can support the required biological, treatment or production outcome.
Irrigation & Horticulture
Delivering oxygen through irrigation water can support aerobic root-zone conditions and oxygen-dependent biological processes.
Livestock Production Water
Nanobubble oxygenation can form part of an integrated approach to managing water as a production input in intensive livestock systems.
Aquaculture
Oxygen availability is fundamental to aquatic production, making efficient oxygen transfer an important part of water management.
Ponds & Waterways
Nanobubble systems can be applied where dissolved oxygen and water conditions need to be improved or actively managed.
Wastewater & Effluent
Improved oxygen transfer can support oxygen dependent treatment processes and form part of a broader wastewater treatment system.
Industrial & Process Water
Nanobubble technology can be integrated into treatment and process water systems where controlled gas transfer supports the required water outcome.

Nanobubble technology has been applied and studied across commercial growing systems, horticulture and water remediation — providing practical evidence of how improved oxygen delivery can influence water and production conditions.

Nanobubble Systems for
Real World Applications
Solari Water and Energy offers a range of nanobubble systems designed for different water volumes, operating environments and treatment requirements. From compact installations to higher-flow applications, each system can be selected and integrated around the water source, required gas transfer and intended outcome.
Rather than treating nanobubble generation as a standalone piece of equipment, Solari considers how it needs to work with the wider water system — including oxygen supply, pumping and other treatment technologies where required.
Nanobubble Generation
The core of the system
Solari’s nanobubble generators introduce gas into the water as ultrafine bubbles. Different configurations allow the technology to be applied across smaller installations, submerged applications and higher-flow treatment systems.
MiniGaLF
A compact ultrafine bubble generator designed for smaller-scale applications and retrofit installations. MiniGaLF can introduce air, oxygen, nitrogen or carbon dioxide into a water stream, providing a practical option where nanobubble generation needs to be incorporated into existing equipment or processes without a larger treatment system.
Submersible Ultrafine Bubble Generator
A complete submersible ultrafine bubble generation system designed to operate directly within tanks, ponds and other water bodies. Its submerged configuration makes it particularly suited to applications where water needs to be circulated and oxygen or other gases introduced directly at the point of treatment.
Nanobubble Pump Skid 737 / 747
A higher-flow nanobubble generation system designed for applications requiring greater water movement and gas transfer capacity. Available in 737 and 747 configurations, the skid-mounted system provides a practical platform for integrating nanobubble treatment into irrigation, livestock water, wastewater and larger production-water systems.
Supporting Oxygen Supply
When the Application Requires More Oxygen
Nanobubble generation and oxygen supply perform different roles within the water system. Where an application requires concentrated oxygen rather than ambient air, Solari nanobubble equipment can be paired with PSA oxygen generation to provide a controlled oxygen source for delivery into the water.
This allows the oxygen supply to be selected around the requirements of the application, while the nanobubble system handles the transfer of that gas into the water.
Industrial Oxygen Concentrators
PSA oxygen concentrators provide an on-site source of concentrated oxygen for applications where a nanobubble system requires a dedicated oxygen supply. Available configurations allow oxygen generation to be matched to the requirements of the system.
Booster Oxygen Concentrators
Booster configurations combine oxygen generation with increased delivery pressure, providing a supporting oxygen source where the nanobubble equipment or system configuration requires higher-pressure gas supply.
Integrated Gas Treatment
When Nanobubbles
Carry More Than Oxygen
Nanobubble technology can also be used to introduce other gases into water as part of a broader treatment process. The same characteristics that make ultrafine bubbles effective for oxygen transfer can be applied where a different gas is required to achieve the treatment objective.
Solari’s ozone nanobubble systems combine ozone generation with ultrafine bubble mixing, creating greater opportunity for the gas to interact with the water during treatment. This allows nanobubble technology to become part of a more integrated treatment approach, selected around the water conditions, application and required outcome.
Solari O₃ Nanobubble Systems — 828 / 838
These systems combine ozone generation with nanobubble mixing in an integrated configuration for water-treatment applications where ozone is selected as part of the treatment process.
Put Nanobubble Technology to Work
The right nanobubble system starts with the water, the application and the outcome you need to achieve. Solari Water and Energy can assess those requirements and determine how nanobubble generation, gas supply and supporting treatment technologies should work together within the wider water system.
