As early as the 19th century, researchers have been using fluid mechanics and physics began for the millimeter bubble in the liquid generation, the rise of the process. The last century 50's, in the chemical field began to bubble and droplet research. After that, the research results of two-phase flow (gas-liquid, liquid-liquid), especially the basic phenomenon of gas-liquid dispersed phase, have greatly promoted the application of large-scale chemical machinery. The miniaturization of gas bubbles is a key technology in the chemical industry to promote the movement of matter and increase the rate of chemical reaction. However, at that time, no microbubble generation technology and means can be applied in chemical industry.
Micro-nano bubble generation technology is the late 20th century, the late 90's, the 21st century in Japan has been vigorous development of its manufacturing methods, including the cycle of shear, pressure dissolution, electrochemical, microporous pressurized, mixed jet, etc., Under certain conditions can produce micro-nano-level bubbles. Micro-nano-bubble water is now widely used in aquaculture agricultural planting sewage treatment bath water metal surface cleaning and other fields.
