What are micro-nano bubbles?

If you see a small factory at the end of a green mountain in Seki-shi, Gifu Prefecture, that is NAC Co.
With Monotransfilm, a micro-nano bubble generator Foamest® and the tiny bubbles B.nano produced by its
unique technology, the company is changing the way the world thinks about bubbles one after another.

Microbubbles are bubbles with a size of 1-1/1,000 mm.
Nanobubbles are bubbles with a size of 1/1,000 to 1/1,000,000 mm.
Micro-nano bubbles are a mixture of bubbles ranging from microbubbles tonanobubbles.

By creating stripes of sponge-like porous areas on the
cross-section of the resin film, special functions such as
viewing angle control and gas permeability can be achieved.
Foamest is made using this gas transmission function.

B.nano penetrates into hard ground and improves the field from the soil. It activates micro-organisms inthe soil, improves plant rooting and increases the effectiveness of fertilisers. It is particularly effective
when used during the seedling stage. Of course, it can be used in both hydroponics and soil cultivation.
Diluting pesticides with B.nano water also allows them to penetrate areas that are often missed, such asat the base of leaves and in the spikelets. This increases the effectiveness and consequently reduces theParts cleaning / Wastewater treatment / Oilwater separation

The penetrating power and negative charge of B.nano are at work in the industrial sector. For cleaning,
B.nano penetrates into nooks and crannies and removes even nano-order dirt. In wastewater treatment,
B.nano captures any fine particles with its negative charge, helping to purify the water and reduce thetreatment burden. This contributes to cost reduction.
Only the B.nano can do this, as it does not cause convection. It is ideal for grease traps that must not
be agitated and industrial products that could be damaged by water flow.

be effective even in large areas, and you can hope for an improvement in the environment that goesbeyond a simple oxygen supply. B.nano is particularly suitable for stress-sensitive fry and shrimp, as it
does not create convection currents.
However, algae also become more energetic, so countermeasures may be necessary.
