It relates to a dishwasher for a business equipped with a water device.

In general, nanobubbles refer to ultra-fine bubbles of 1 μm or less, which cannot be seen with the naked eye, with a diameter of less than a nano unit.

Typically, it is an air particle that is 1/2,000 of the size of a normal bubble and is finer than 25㎛ pores of the skin. When it disappears, it generates 40KHz ultrasonic waves, generates a high sound pressure of 140db, and generates an instantaneous high temperature of 4,000°C to 6,000°C. do.

Normal bubbles rise in the water and rupture at the surface, but the micro-nanobubbles shrink by pressure in the water and dissipate by generating various energies.

These nanobubbles are microbubbles that are generated when water and air are violently rotated, mixed, and agitated with ultra-fine bubbles, and are generated in the process of shrinking in water, and stay and dissolve for a long time.

On the other hand, nanobubbles as described above are used in various fields due to physical and chemical properties such as "gas dissolution effect, self-pressurization effect, charging effect", and in recent years, especially in fisheries such as fish and shellfish farms, and in agriculture, hydroponic cultivation , Food processing, livestock industry, and medical field for precise diagnosis.In various fields, physical therapy, high purity water treatment, sterilization treatment or agricultural and fishing wastewater treatment, industrial wastewater treatment, ultra-precision electronic component semiconductor wafer cleaning and lakes, rivers, It is used for environmental devices such as improvement of water quality in the sea.
