The particle size of the foaming liquid particles of the dissolved air flotation machine equipment is between 0.25 and 2.5mm, and a small amount of large particles of this equipment are about 10mm. Therefore, microbubbles of about 1 mm have a good adsorption effect on most suspended particles, which is also the direct reason for the super strong dissolved air rate during the operation of the dissolved air flotation machine.

The dissolved air flotation machine uses clean water or partially treated return water to inhale and mix air through the microbubble generator to form dissolved air and water, which is released under reduced pressure in the air floatation tank, and the air is dissolved in the water by 20-30μm bubbles It forms sediment, has a high specific surface area and adsorption capacity, and can effectively remove suspended solids in sewage with different concentrations.
