Revolution in Water Treatment

The visible bubbles that are observed in daily life, such as in fizzy drinks (mm range), have large diameter that make them rise and burst. Bubbles in the range of 10 to 100 μm (micron, equal to 1/1000 mm) called fine bubbles (FBs), have very slow rising speed and can still be observed in the cloudy aspect of the water.

Ultra fine bubbles (UFBs) are gas bubbles which size is below 100 nm (1/10,000 mm, proportion of a coin compared to Eiffel tower!) and are invisible to the eyes.

They have very peculiar characteristics that can be used in various fields: water and wastewater treatment, surface water cleaning, soil remediation, agriculture and aquaculture. NT provides technologies producing high concentration of these UFBs of any gas, for eco-friendly and cost-effective solutions adapted to the needs of the customers.
