Q: Why does the sub-100-nanometer size matter?

At sub-100-nanometer diameters, water no longer behaves like a passive carrier — it becomes an active reaction medium. Internal gas pressure rises sharply (Laplace pressure), bubbles carry a strong negative zeta-potential that prevents coalescence, and they generate reactive oxygen species on collapse, enabling chemical-free oxidation and disinfection.

Q: How long do nanobubbles stay in water?

In stable conditions, Aquadei nanobubbles persist for weeks to several months. Persistence depends on water chemistry, temperature, and turbulence, but the bubbles do not simply rise out of solution like conventional aeration.

Q: What gases can be loaded into nanobubbles?

Aquadei systems can generate nanobubbles from oxygen, ozone, air, CO₂, nitrogen, and hydrogen depending on the application — from aquaculture oxygenation to chemical-free pool disinfection and agricultural root oxygenation.

Q: What industries use Aquadei nanobubble technology?

Agriculture, aquaculture, swimming pools and spas, hospitality, oil & gas, mining, municipal water and reuse, industrial process water, wastewater treatment, commercial real estate, and research laboratories.

Q: Can nanobubbles replace chlorine in swimming pools and spas?

Yes. Oxygen and ozone nanobubble systems provide continuous, chemical-free disinfection and oxidation, keeping water sanitized without the chloramine odor, skin irritation, or harsh byproducts associated with traditional chlorine treatment.

Q: How do nanobubbles help agriculture and irrigation?

Oxygen-rich nanobubble irrigation water elevates dissolved oxygen at the root zone, accelerating root growth, improving nutrient uptake, suppressing root pathogens, and increasing yield while reducing water consumption.

Q: Are nanobubbles effective for wastewater and industrial treatment?

Yes. Nanobubbles boost aerobic biological activity, accelerate BOD/COD reduction, oxidize odors and contaminants, and reduce sludge volumes — often allowing existing plants to handle higher loads without new infrastructure.

Q: Can nanobubbles be used in drinking water?

Absolutely. Oxygen nanobubbles enhance taste, freshness, and dissolved-oxygen levels in bottled and treated water without adding chemicals. Our O₂ True product line is built specifically for premium oxygenated drinking water.

Question 1

What are nanobubbles?

Accepted Answer

Nanobubbles are ultra-small gas bubbles — typically smaller than 100 nanometers in diameter — suspended in water. Unlike conventional bubbles that rise and burst at the surface, nanobubbles remain stable in solution for weeks or even months, dramatically increasing the dissolved gas concentration and creating an active reaction medium.

Question 2

How are nanobubbles different from microbubbles or regular aeration?

Accepted Answer

Microbubbles (1–100 µm) rise quickly and lose most of their gas to the atmosphere. Nanobubbles (<100 nm) have neutral buoyancy, a negative surface charge, and a vastly larger surface-to-volume ratio. The result is gas-transfer efficiency that can be many times higher than conventional aeration, with long-term oxygen retention in the water column.

Absolutely. Oxygen nanobubbles enhance taste, freshness, and dissolved-oxygen levels in bottled and treated water without adding chemicals. Our O₂ True product line is built specifically for premium oxygenated drinking water.

Question 11

Are nanobubbles safe?

Accepted Answer

Yes. Nanobubbles are simply ultra-small bubbles of naturally occurring gases (oxygen, air, ozone) dissolved in water. There are no additives, no residues, and no harmful byproducts. The technology is widely deployed in food-grade, agricultural, and drinking-water applications.

Question 12

Are nanobubble systems environmentally friendly?

Accepted Answer

Yes. Nanobubble systems reduce or eliminate the need for chlorine, ozone-only treatment, and chemical disinfectants; lower energy use compared to conventional aeration; and can significantly cut water consumption in agriculture and industrial processes.

Question 13

Do nanobubbles save energy?

Accepted Answer

Yes. Because nanobubbles transfer gas far more efficiently than coarse aeration, the same dissolved-oxygen targets can be reached with significantly less compressor or blower energy — often a 30–50% reduction in aeration energy.

Question 14

Can the Mizue nanobubble showerhead really improve skin and hair?

Accepted Answer

Mizue produces ultra-fine bubbles that penetrate pores and lift sebum, dirt, and product residue without harsh detergents. Users report softer skin, healthier scalp, and reduced soap usage. Full results are documented in our Mizue brochure on the Publications page.

Question 15

How do I choose the right Aquadei nanobubble generator?

Accepted Answer

It depends on water volume, target gas, flow rate, and application. Our team will scope the project with you — pool, greenhouse, pond, processing plant, or industrial loop — and recommend the right unit, from the compact Nano-15 to vertical skid systems and BioBooster wastewater units.

Question 16

How are Aquadei nanobubble systems installed?

Accepted Answer

Most systems are inline, side-stream installations that connect to existing pumps and piping. No tanks need to be drained, and integration with existing filtration or dosing systems is straightforward. Our installation guides on the Publications page walk through each product in detail.

Question 17

What maintenance do nanobubble generators require?

Accepted Answer

Aquadei systems are designed for low maintenance — periodic inspection of the gas supply, inline filters, and pump health. There are no consumable chemicals and no membranes that need frequent replacement.

Question 18

Do you ship internationally?

Accepted Answer

Yes. Aquadei products and partner-built systems ship worldwide, with regional support partners for installation and service. Contact us to confirm shipping and support for your country.

Question 19

Where can I find research and product documentation?
