I. Introduction of dissolved air flotation machine:
Dissolved air flotation machine is mainly used for solid - liquid or liquid - liquid separation. Through the gas dissolution and release system in the waste water to produce a large number of fine bubbles, so that it adheres to the density of solid or liquid particles close to the water in the wastewater, resulting in the overall density less than the state of water, and rely on buoyance to make it rise to the water surface, so as to achieve the purpose of solid-liquid or liquid-liquid separation.
Two, dissolved air flotation machine application scope:
1. Separation of fine suspended solids, algae and other microaggregates on the surface.
2. Recycle useful substances in industrial wastewater, such as pulp in papermaking wastewater.
3, instead of the secondary sedimentation tank and concentrated water sludge and other suspended matter.
Three, dissolved air flotation machine advantages:
Long-term stable performance, easy operation, easy maintenance, low noise;
The efficient adsorption of microbubbles and suspended particles in the dissolved air flotation machine improves the removal effect of SS;
Air flotation machine automatic control, simple maintenance;
The multi-phase flow pump of the dissolved air flotation machine can be carried with pressurized pump, air compressor, large dissolved gas tank, jet and release head, etc;
The dissolution efficiency of dissolved air water is 80-100%, 3 times higher than the traditional floating efficiency of dissolved air;
Multi-layer mud discharge to ensure water discharge effect;
