Conventional technologies to aerate liquids with gas, typically oxygen, are not efficient.   Nanobubbling has developed as a gas transfer technology providing more efficient dispersion and stability in liquids. Nanobubbles are minuscule gas-filled spheres from 50-500 nm in diameter that can be generated with a variety of gases, including oxygen, ozone, nitrogen, hydrogen and carbon dioxide. Their small size and unique physical properties mean they are more stable than macro or microbubbles enabling them to remain suspended in liquid solutions over extended periods:

1.  High Internal Pressure.  Tiny size creates significant internal pressures, resulting in unique chemical reactions at the bubble’s interface that promote increased gas dissolution in liquids.
2.  Large Surface Area.  Tiny size creates a large surface area : volume ratio which enhances capacity for highly efficient gas transfer.  This enables faster saturation of liquids with gases, beneficial in beverage carbonation and wastewater treatment.
3.  Surface Charge.  Nanobubbles typically have a negative surface charge, making them attractive to positively charged contaminants opening applications for water and liquid purification and soil remediation.
4.  Durability.   Nanobubbles can remain suspended in liquids for extended periods depending on temperature which opens access to aquaculture, agriculture, industrial and medical applications.

The smaller the device the better the results.

An innovative and elegant next generation solution.

Global Cavitation, a Cairns-based company, has developed a patented next generation nanobubbling technology based on the principles of hydrodynamic cavitation that can generate nanobubbles at 7nm, 14x smaller than the largest global competitor.  This technology has no moving parts, does not need filters, requires almost no maintenance, is scalable and easily retrofitted to existing infrastructure and instantly infuse gas into water at scale as shown below.  This technology is a market leader.  Competitor machines are more complex, prone to
blockage, require regular maintenance, are more expensive and less versatile.

Global Cavitation is industrialising and negotiating contracts to roll out its hydrodynamic cavitation technology across aquaculture, agriculture and wastewater Europe, North America, and Middle East markets.  Why offshore?  Australian aquaculture and agriculture farmers prefer to validate new Australian technologies offshore where the new technology landscape and the problems it solves are more clearly perceived.
