Super-Nano Bubble Generator
High-Concentration Nano Bubbles
Generates a high concentration of ultra-fine micro and nano bubbles, down to the nanometre range, for maximum dissolved oxygen — bubbles that rise slowly, stay suspended longer and dissolve gradually, for maximum oxygen utilization with minimal waste.

What it’s for
Smaller Bubbles, Longer in the Water
The super-nano generator produces bubbles as small as the nanometre range, offering exceptional gas-liquid contact. Nano bubbles rise slowly and remain suspended longer, which increases oxygen transfer efficiency, and they gradually dissolve into the water rather than escaping at the surface — maximum oxygen utilization with minimal waste.
The result is higher dissolved oxygen for biological treatment and better water quality, supporting natural purification and ecological restoration. It is engineered for high-performance aeration with optimised energy use, and built for consistent, low-maintenance service across a wide range of water treatment applications.

Applications
Where It’s Specified

Domestic sewage treatment, improving biological treatment and water quality.
Black and odorous water bodies, supporting natural purification of polluted water.
Deep-drain wastewater from rivers and lakes, and ecological restoration projects.
Common questions
Frequently Asked Questions
How is it different from the Micro-Nano generator?
It runs at 8500 rpm, against 2850 rpm for the Micro-Nano, to produce a higher concentration of nanometre-range bubbles that stay suspended longer. The Micro-Nano covers larger duties — up to 9 kW and 24 kgO₂/h — where the Super-Nano tops out at 4 kW and 9 kgO₂/h.
Why do smaller bubbles matter?
Nano bubbles rise slowly and remain suspended longer, so more of their oxygen transfers into the water, and they gradually dissolve rather than escaping at the surface — more oxygen used, less wasted.
When is it worth it over a standard aerator?
When a site needs higher dissolved-oxygen performance or pollutant breakdown than standard aeration typically achieves — black and odorous water bodies or deep-drain wastewater, for example.
