Better Gas–Water Contact with
Nanobubble Technology

Nanobubbles disperse gas as ultrafine bubbles, increasing gas–water contact for oxygen transfer, ozone oxidation, cleaning, and functional water. Honour Tech engineers systems for real process conditions.

01

What Are Nanobubbles?

Nanobubbles are ultrafine bubbles that rise slowly and remain dispersed longer, increasing gas–water contact.

Nanobubbles are gas bubbles smaller than 1 μm in diameter, also referred to as ultrafine bubbles.
Size comparison of conventional bubbles, microbubbles, and nanobubbles based on ISO 20480-1:2017

Bubble-size ranges (Source: ISO 20480-1:2017)

Larger Interfacial Area

Smaller bubbles create more gas–water interface, supporting gas transfer.

Brownian Motion

Their small size and irregular motion help them remain dispersed longer than larger bubbles.

High Oxygen-Transfer Efficiency

Small bubbles and longer contact can improve oxygen transfer. One Honour Tech test measured ~90% efficiency under specific conditions.

Surface Charge

Surface charge may influence fine particles and contaminants, supporting separation under suitable water and process conditions.

02

Small Bubbles, More Contact Time

Performance depends on the gas, process, and operating conditions—not bubble size alone.

Conventional Bubbles

Rise quickly to the surface, limiting gas–water contact time.

Nanobubbles

Remain dispersed longer and provide a larger interface, supporting gas transfer.

01 · GAS TRANSFER Transfer O₂, O₃, CO₂ and Other Gases

  • Process-integrated system design

04 Validation-Based Application

  • Confirm water quality and target
  • Pilot/comparative tests when needed
05

Application Conditions & Validation

Nanobubbles supplement rather than automatically replace existing processes. Results depend on:

  • Source-water or wastewater quality
  • Applied gas
  • Flow and circulation time
  • Temperature and operating pressure
  • Organic/contaminant load
  • Existing process and performance target

We review process conditions and use lab or pilot tests when needed before system selection.
