Nanobubble Ozone Technology – Advancing Mass Transfer Through Physics

As water treatment demands intensify, nanobubble technology is emerging as a method to significantly enhance ozone delivery. Understanding the fundamental physics behind these microstructures is essential for successful implementation.

Nanobubbles, which measure less than 200 nanometers, feature a critical negative surface charge, also known as zeta potential. This charge provides electrostatic stabilization, preventing the bubbles from collapsing or aggregating like conventional aeration systems. The result is a dramatic increase in both mass transfer efficiency—with some systems achieving over 99%—and ozone persistence, allowing the oxidant to remain stable in the aqueous phase for extended periods.

These persistent, charged microstructures offer several practical advantages, including improved penetration into biofilms and porous media, and enhanced localized oxidation reactions at the bubble interface. Learn how this technology is successfully applied across various sectors, from improving oxidation in high-organic surface water to enhancing fouling resistance in membrane systems.
