2021 Ver.

It is a technology developed by applying the shear resistance relationship between the interface of the object and the adjacent area. When gas(ex. oxygen) is splitted into nanosize by the shear force generated at the interface of the object, dissolved gas is increased. Nano-sized bubble(gas) exists in water for a long time without degassing, and dissolved gas is maintained high for a long time.

The 2021 version of the N2BG consists of one pump and one bubble generator. The configuration is simpler than the previous N2BG, making installation and maintenance easier. The pump is a self-priming pump with a pressure of 4-4.5kgf/cm^2. The pressure of the pump is the energy for making shear forces, and the higher the pressure, the smaller the bubble. Gas is injected in front of the pump and in an amount that will not cause cavitation in the pump. The 2021 version of the N2BG has no blockage caused by solids. So It can be applied to water with high solids concentration such as fish farms and wastewater treatment plants. And it is possible to install the bubble generator in parallel, so the capacity can be increased to 1,000m^3/day or more.

When the air was used for N2BG, the dissolved oxygen concentration increased 6mg/L compared to the raw water and the dissolved oxygen solubility was over 180%. If this device is used in water with a water temperature of 28 degrees, dissolved oxygen can be kept above 14mg/L by air alone. When oxygen gas is used in the N2BG, the dissolved oxygen concentration increases to over 44mg/L.The nanobubbles in the sealed bottle remained intact even after 30 days. And nanobubble existed even after the nanobubble water had frozen and melted.
