Nanobubble FAQ for Real-World Applications

A. They differ in size, behavior in water, and suitable applications.
Ordinary bubbles rise quickly; nanobubbles are smaller and can remain dispersed longer.
Microbubbles may suit flotation; nanobubbles can suit gas transfer or contact with fine surfaces.

A. Disinfection from nanobubbles alone should not be generalized across conditions.
Some studies report reactive species under specific conditions, but real effects vary with water quality and operation.
For defined oxidation or microbial control, use a suitable gas such as ozone and manage dose, contact time, residual ozone, and safety.

A. Bubble size and residence time matter, but they do not guarantee process performance.
Bubble behavior changes with temperature, turbidity, organics, salts, and operation; lab values do not transfer directly to every site.
Judge performance by the target metric—DO, ozone, pH, cleaning, etc.—over the required run time.

A. Smaller bubbles can increase gas–water interface and contact time.
Smaller bubbles provide more interface and longer contact, supporting transfer of O₂, O₃, CO₂, and other gases.
Transfer also depends on gas dose, temperature, pressure, water quality, and circulation. Technology page for more detail.

A. Choose based on target DO, available operating time, and cost.
Air is usually cheaper; oxygen can suit higher DO targets or faster response.
Selection considers flow, current/target DO, run time, and gas/energy cost. O₃, CO₂, and H₂ are chosen by process purpose.

A. Applications range from laundry and car wash to parts and process-equipment cleaning.
Applications include laundry, car wash, dishwashing, parts, and precision/process cleaning, where better surface and gap contact may help.
Results vary with soil, surface, temperature, flow, pressure, detergent, and wash method; comparison testing may be needed.

A. No. Results depend on the target and site conditions.
Water quality, gas/dose, flow, time, temperature, pressure, pollutant load, and process design all matter.
Review site data first and use lab or pilot testing when needed.

A. No. NTA characterizes bubbles; process performance must be verified separately.
NTA reflects one sample and time; real operation varies, so bubble metrics alone are not enough.
Pair NTA with process indicators such as DO, ozone, COD, color, pH, cleaning efficiency, and run stability.

A. We check both bubble characteristics and process indicators.
NTA measures bubble size/count; field checks compare DO, dissolved ozone, pH, ORP, COD, cleaning efficiency, or other target metrics.
Cloudiness after shaking is not an objective test because entrained air and other bubbles can affect it.

A. Look beyond bubble numbers to process-engineering capability and field data.
Check gas-specific experience, flow/pressure range, stability, maintainability, integration, commissioning, support, and pilot capability.
Honour Tech designs its core mixers and systems in-house and has supplied 600+ systems since 2017.

A. Often yes, but the existing process must be reviewed first.
Integration is based on pump flow/pressure, piping, tanks, water path, run time, and connection points.
Existing equipment often remains. The full process is checked to avoid gas loss or hydraulic interference with other equipment.

A. Economics should be based on total operating cost and process benefit, not equipment price alone.
Initial cost can exceed a simple diffuser because pumps, mixers, gas supply, and controls may be required.
Compare equipment, power/gas, water, chemicals, wastewater, maintenance, and productivity as total cost of ownership (TCO).

A. We recommend pilot testing when site variables are large or the performance target is critical.
Pilots are especially useful for difficult wastewater, variable cleaning conditions, strict targets, or tight gas control such as ozone.
Typical path: data review → feasibility → lab/pilot → selection/quote → design/fabrication → commissioning → performance check.
