Air flotation separation is the air and water under certain pressure and conditions, so that the gas is greatly integrated into the water, and then the pressure formed through a special device to release the pressure, the rapid generation of a large number of micro-bubbles, and the suspended matter in the water (flocculent after the addition of drugs) in full contact with the bubbles and the suspended matter to form a floc, whose density is less than water, so that folder flocs quickly rise to the surface of the water, the suspended matter in the liquid surface aggregation of the dregs, scrape the dregs to achieve the effect of solid-liquid separation.
