    Using the different solubility of water under different pressures, micro-bubbles are generated in the water under pressurized or negative pressure conditions, replacing the air flotation process of traditional air-entraining equipment to draw air into the water.

    Dissolved air flotation is mainly used in sewage treatment systems, which has a miraculous effect on algae removal and is a new breakthrough in sewage treatment systems.

    The working principle of dissolved air flotation is: the air sent by the air compressor to the air tank is brought into the dissolved air tank through the jet device, and is forcibly dissolved in the water under the pressure of 0.35Mpa to form dissolved air water and sent to the air flotation tank. In the case of sudden release, the air dissolved in the water precipitates, forming a large number of micro-bubble groups, which are in full contact with the suspended solids in the pumped and flocculated sewage, and adsorbed in the flocculated suspended solids during the slow rise process, so that its density decreases and floats to the surface, so as to achieve the purpose of removing SS and CODcr.

    Introduction of dissolved air flotation machine:

    The dissolved air flotation machine is mainly used for solid-liquid or liquid-liquid separation. A large number of fine bubbles are produced in water through the dissolved air and release system, so that they adhere to the solid or liquid particles whose density is close to that of water in the wastewater, resulting in a state where the overall density is less than that of water, and rely on buoyancy to make them rise to the water surface, so as to achieve the purpose of solid-liquid or liquid-liquid separation.

    Application scope of dissolved air flotation machine:

    1. Separate fine suspended solids, algae and other micropolymers in the surface.

    2. Recycle useful substances in industrial wastewater, such as pulp in papermaking wastewater.

    3. Replace suspended solids such as sludge in secondary sedimentation tanks and concentrated water.

    Advantages of dissolved air flotation machine:

    1. Long-term stable performance, easy operation, easy maintenance, low noise

    2. The efficient adsorption of micro-bubbles and suspended particles in the dissolved air flotation machine improves the removal effect of SS

    3. The automatic control and maintenance of the air flotation machine are simple

    4. The multiphase flow pump of the dissolved air flotation machine can be equipped with a pressurized pump, an air compressor, a large dissolved air tank, a jet and a release head, etc

    5. The dissolving efficiency of dissolved air water is 80-100%, which is 3 times higher than the traditional dissolved air flotation efficiency

    6. Multi-layer mud discharge to ensure the water outlet effect
