What sewage can be treated by air floatation machine?

The principle of the air flotation machine is to release a large number of micro bubbles into the water, so that the suspended solids attached to the water can be lifted to the surface of the liquid through the effect of buoyancy.

Features of air flotation device:

1. Large processing capacity, high efficiency and small land occupation.

2. The process and equipment structure are simple and easy to use and maintain.

3. The effluent quality is good, not only low turbidity and SS content, but also high dissolved oxygen.

4. The water content of the discharged scum is lower than that of the sludge discharged from the sedimentation tank, which brings greater convenience to the sludge disposal and saves the cost of sludge disposal.

Principle of air flotation machine application scenario:

1. Solid liquid separation: the particle size of solid particles in sewage is very small, and the density of particles and flocs formed is close to or lower than that of water, which can effectively solve this problem.

2. In terms of water supply, it can be used for purification of water sources with high algae content and polluted water.

3. Liquid liquid separation: separation and recovery of petroleum, organic solvent, surfactant and various metal ions from sewage.

4. Improve the sewage system with limited land use, and solve the hydraulic load and solid load.

5. It is effectively used for activated sludge thickening.
