Nano bubble（Ultra Fine Bubble）

The nano bubble technology is the Japanese technology that can generate ultra fine bubbles of a nanometer size and make them be dissolved in water.

The nano bubble technology is the Japanese technology that can generate ultra fine bubbles of a nanometer size and make them be dissolved in water.
If it is applied to aquaculture of fish and shellfish, a substantial rise in the efficiency can be expected.
The commonly used air diffusers could not increase the amount of dissolved oxygen, since the air it generates would float up to the surface immediately.
With the application of the nano bubble technology, you can produce a large amount of dissolved oxygen with small electric power and, beside, you can install the device reasonably in any type of places without air diffusers.

Ways of utilizing the technology: The case of utilizing in a culture pond

• Desire to make the cultured fish larger.
• Desire to keep the water in the culture pond clean.
• Desire to reduce the costs for electricity.
• Desire to introduce the oxygen supplying system at a low price.

The nano bubbles can be used in various ways, other than application to the fishery aquaculture: If used for agriculture, it will promote the growth of agricultural produce, if used for the cleaning purposes, the cleaning capacity will be augmented and, if used for purification of water, it will activate the microorganism to strengthen the purifying capacity.
In addition, concerning the gas that can be made into nano bubbles, the technology can apply to dissolution of not only the air in the water but various kinds of gases.

• O₂ (Oxygen) Rearing of agricultural produce, activation of microorganism, and aquaculture of fish.
• O₃ (Ozone) Sterilization and high-grade water treatment.
• CO₂ (Carbon dioxide) Carbonated springs, and neutralization processing.
• Air Cleaning, aquaculture of oysters, enclosure of fragrances.
• N₂ (Nitrogen) Food processing and maintenance of freshness.
• F (Fluorine) Utilization in the medical fields.

N.B.: The effects mentioned above are some of many examples, including those whose mechanism is being verified.
