The micronanometer aeration machine, also known as the micronanometer oxygenation machine, consists of a pump, micronanometer bubble generator, pressure gauge, aeration head, and some pipe fittings. It is a set of equipment specifically developed for river treatment and dissolved oxygen management. The principle involves using nanotechnology to initially compress a large amount of air into a large number of non-pressurized microbubbles with a diameter of 0.25mm. Then, by utilizing the release system, these 0.25mm non-pressurized microbubbles are highly dispersed in a semi-vacuum state through both gas and liquid phases, producing micronanometer bubbles with diameters less than 3μ and nanobubbles, collectively termed as micronanometer bubbles. These bubbles are released into the water to rapidly enrich oxygen, achieving the effect of increasing dissolved oxygen in the water.
