ClearFlow Micro-Nanobubble Generators are designed to produce micro- and nanobubbles for water treatment, aquaculture, agricultural irrigation and other water-related applications.
The system generates bubbles ranging from approximately 80 nm to 20 μm. Compared with conventional aeration bubbles, micro-nanobubbles can remain suspended in water for longer periods and provide a larger gas-liquid contact area, supporting efficient gas dissolution and mass transfer.
With a reported gas-liquid dissolution rate of over 95%, ClearFlow micro-nanobubble generators can work with different gases, including air, oxygen, ozone and nitrogen, depending on the application requirements.
ClearFlow offers three product series to meet different project needs:
CF-NBC Compact Series: For hydroponics, indoor farming, laboratories and small aquaculture systems.
CF-NBW Wastewater Series: For wastewater treatment, dissolved air flotation (DAF), oxidation and water reuse.
CF-NBI Irrigation Series: For agricultural irrigation, aquaculture ponds, lakes and landscape water applications.
With multiple capacity and power configurations available, ClearFlow can provide suitable micro-nanobubble solutions for different water treatment and circulation requirements.

What Are Micro-Nanobubbles?
Micro-nanobubbles are extremely small gas bubbles generated and dispersed in water. Their small size gives them a relatively large total gas-liquid contact area and different suspension characteristics compared with conventional aeration bubbles.
Depending on the gas used and the application, micro-nanobubble technology can support:
Improved gas-liquid mass transfer
More efficient gas dissolution
Water oxygenation and circulation
Ozone-assisted oxidation processes
Aquaculture water quality management
Agricultural irrigation water treatment
The actual treatment performance depends on bubble size distribution, gas type, water quality, operating pressure and system configuration.
