What Are Nanobubbles?

Nanobubbles are gas-filled bubbles typically smaller than 1 μm in diameter—thousands of times smaller than visible bubbles.

At this scale, bubbles behave differently from conventional macro- or micro-bubbles. Instead of rising quickly and escaping, nanobubbles remain suspended in water for extended periods due to their near-neutral buoyancy and unique surface properties.

These characteristics make nanobubbles especially effective for applications where stable gas delivery, high contact efficiency, and controlled interaction with liquids are required.

How Nanobubbles Behave in Water

Nanobubbles exhibit distinct physicochemical behaviors compared to conventional bubbles generated by aeration or gas injection.

Traditional Bubbles

Nanobubbles

Because of their size and surface charge, nanobubbles:

This results in significantly improved gas utilization compared to traditional bubbling systems, where most gas escapes before participating in the process.

Core Functional Behaviors:

Extended Gas Retention
Gas remains dissolved and available for reaction or interaction
Improved Mass Transfer
More gas participates in the intended process
Uniform Distribution
Reduced dead zones and localized inefficiencies
Controlled Interaction
Enables consistent, repeatable system performance

Why PureNanoTech’s Nanobubbles Perform Differently

Not all nanobubbles are created equal. Performance depends heavily on generation method, bubble purity, size distribution, and system stability.PureNanoTech’s proprietary generation approach is engineered to maximize functional performance rather than simply producing small bubbles.

Performance Advantages

Ultra-Small and Stable Nanobubbles

PureNanoTech nanobubbles remain stable in water for extended periods—typically <200 nm and exceeding 100 days—supporting long-lasting system performance.

High Gas Transfer Efficiency

By maximizing gas retention and contact, PureNanoTech systems achieve over 90% gas utilization efficiency.

Reactive Oxygen Species (ROS) Effects

Under appropriate conditions, nanobubbles can support ROS-related effects that enhance cleaning, hygiene, and oxidation processes.

Low Energy, Low Pressure Operation

Systems are designed to operate without high-pressure pumps or aggressive mechanical forces, reducing energy consumption and wear.

Multi-Gas Capability

PureNanoTech systems support O₂, O₃, H₂, N₂, CO₂, air, and other gases, enabling application-specific tuning.

How Nanobubbles Transform Ozone Performance

Ozone is a powerful oxidant, but its effectiveness is often limited by rapid decay, inefficient gas transfer, and off-gassing losses. When ozone is delivered using nanobubbles, these constraints are significantly reduced.

Nanobubbles change how ozone behaves in water, enabling more efficient, stable, and controlled oxidation performance across treatment and disinfection systems.

Extended Ozone Stability

Extended Ozone Stability

Nanobubbles help stabilize ozone in water, extending its effective lifetime and allowing more time for oxidation reactions to occur.

Higher Gas–Liquid Transfer Efficiency

Higher Gas–Liquid Transfer Efficiency

A greater proportion of injected ozone dissolves and participates in treatment rather than escaping as off-gas.

Reduced Off-Gassing and Ozone Loss

Reduced Off-Gassing and Ozone Loss

Improved gas retention lowers ozone release into the environment, enhancing safety and operational control.

Improved Oxidation Effectiveness

Improved Oxidation Effectiveness

Enhanced contact efficiency supports stronger and more consistent oxidation against microorganisms and contaminants.

Lower Ozone Dosage Requirements

Lower Ozone Dosage Requirements

Increased utilization efficiency often allows systems to achieve target performance with reduced ozone input.
