Dissolved Air flotation is a kind of equipment to remove all kinds of industrial and municipal sewage suspended solids, grease and various kinds of glue.

Air flotation equipment is mainly used for solid-liquid or liquid-liquid separation. Through dissolved gas and release system, a large number of tiny bubbles are generated in the water to make them adhere to the solid or liquid particles with a density close to that of water in the wastewater, causing the overall density to be less than that of water, and lifting them to the surface by buoyancy, so as to achieve the purpose of solid-liquid or liquid-liquid separation. In the field of water treatment, air flotation equipment is applied in the following aspects:

1. Separate fine suspended matter, algae and other micro-aggregates in surface water;

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

3. Separation and concentration of water sludge instead of secondary sedimentation tank.
