Micro-Nano Bubble Generator Technology
The Ultra-Micro Nano Bubble Generator Is A New Technology Water Treatment Equipment independently developed
by LOREN Industry Co.,Ltd. Utilizing the synergistic effect of "super-soluble air-explaining technology" and
"nano-dispersion technology", water and air are highly compatible and mixed, ultrasonic cavitation
dispersion releases high-density, uniform micro-nano bubbles, and the air initially compressed into a large
amount of 0.25 mm bubbles, and then use the release system to highly disperse the gas and liquid phases
in a semi-vacuum condition to produce micro-sized bubbles and nano-sized bubbles with a diameter of less
than 3μm, which are released into the water body to form a milky white gas-liquid mixture Body, achieve the
effect of rapid oxygenation. The technology has obtained 35 national patents, has major innovations, and
has developed a series of special equipment for river treatment. The high-density bubbles released by the
equipment surround the pollutants and eventually burst into the water. The bubbles are completely dissolved
in the water, effectively degrading the pollutants in the water. Micro-nano bubbles can provide dissolved oxygen
to the water, inhibit the increase in sediment, digest the existing sludge, and create a good sediment environment.
Spherical nanobubbles suspended in liquid with diameters between 200 nanometers and 3 microns. The surface
of the bubble is rigid, similar to a high-pressure balloon, and is not easy to burst. Play the role of high-efficiency
aeration, effective algae removal, sediment digestion, and circulating water.
