Ordinary bubbles rise in water rapidly and burst on the water surface releasing the encapsulated gas into the atmosphere. Fine bubbles, on the other hand, stay in water because they are extremely slow to rise. Bubbles in diameter of 10 microns rise 3mm per minute.
Fine Bubble (Micro, Nano)
Fine Bubble Characteristics
As the bubble size becomes smaller, inner pressure increases due to surface tension of the interface between gas and liquid matter. Logically, the pressurization process is infinite. Pressurization promotes dissolution of gas into the water (Henry’s Law) as the fine bubbles implode.
Ultra-fine Bubbles (Nano-size)
Ultra-fine Bubble Characteristics
Ultra-fine bubbles have been confirmed to stay in a liquid for over six months, moving horizontally in solution due to their Brownian movement. They do not rise to the surface for release into the atmosphere.
