During the operation of the pressurized dissolved air flotation machine, the dissolved air pump absorbs water while inhaling, and the pump has high pressure mixing and vapor-liquid dissolving efficiency. A complex system consisting of a device and a release head.

The pressurized dissolved air flotation machine can operate at low pressure to a certain extent. The dissolved air efficiency of the entire equipment is as high as 99%, and the release rate is as high as 99%. The efficient adsorption of microbubbles and suspended particles improves the removal effect of SS. The dissolution efficiency of dissolved air and water is 80-100%, which is 3 times higher than that of traditional dissolved air flotation.

During the operation of the pressurized dissolved air flotation machine, the raw water enters its mixing reactor, and the chemical is added to the mixed reactor, so that separable flocs can be formed, and the pretreated sewage enters the air flotation device. The micro-bubbles (the diameter of the bubbles range from 30 to 50um) released in the sewage and the gas-water mixture in the inlet chamber are mixed. These tiny air bubbles adhere to the flocs in the sewage, forming aerosols with a specific gravity lower than that of water. The air floating body rises to the water surface and condenses into oil slick (or scum), which is scraped to the oil (slag) tank by scraping oil (slag) machine.
