Question 1

What’s the difference between ozone and oxygen nanobubbles?

Accepted Answer

The nanobubble technology is the same; the gas determines the treatment effect. Oxygen nanobubbles are used to increase dissolved oxygen and support aerobic biological processes. Ozone nanobubbles are used mainly for oxidation and disinfection.

Question 2

When should I use ozone instead of oxygen nanobubbles?

Accepted Answer

Use ozone when the treatment goal is oxidation rather than oxygenation. Typical applications include tertiary disinfection, sulfide and odour control, colour reduction, and treatment of certain compounds that are difficult to address biologically.

Question 3

Are ozone nanobubbles safe for fish?

Accepted Answer

Ozone must be carefully controlled in aquaculture because residual ozone can harm fish and other aquatic organisms. Oxygen nanobubbles are the more appropriate choice when the goal is continuous oxygenation.

Question 4

Do nanobubbles replace conventional aeration?

Accepted Answer

They can reduce reliance on conventional aeration in some applications, but they are not automatically a direct replacement in every plant. The right setup depends on oxygen demand, basin design, treatment objectives, and existing equipment.

Question 5

Can oxygen and ozone nanobubbles be used in the same treatment system?

Accepted Answer

Yes. They can serve different stages or treatment objectives within the same overall process. Oxygen may support ongoing biological treatment, while ozone is applied separately for targeted oxidation or disinfection.
