Shengshi - Dissolved Air Flotation Machine (DAF)

In the sewage treatment process, the air flotation machine can flocculate and settle suspended matter in the water. It mainly consists of a pressure dissolved air tank, an ejector, a dissolved air releaser and an air flotation tank. First, the sewage to be treated flows into the pressure air dissolving tank, and air is introduced through the ejector for air dissolving. Then, the air dissolved in the sewage is released through the dissolved air releaser to form tiny bubbles. These tiny bubbles combine with pollutants such as suspended solids, grease and various colloids in the water to form scum. Finally, the scum is separated from the water through an air flotation tank.

1. Remove oil and TSS.
2. Separate small particles and algae in groundwater.
3. Recover valuable products in industrial sewage such as paper pulp.
4. Act as secondary sedimentation tank to separate and concentrate suspended particles and sludge.

1. Large capacity, high efficiency and small occupying space.
2. Compact structure, easy operation and maintenance.
3. Silt expansion elimination.
4. Aerate to the water while air floating, it has an obvious effect to the elimination of active agent and foul smell in water. Meanwhile, the increased dissolved oxygen provides a favorable condition to the follow-up process.
5. It can achieve the best effect in adopting this method when disposing the water with lower temperature, lower turbidity and more algae.
