Background technique

The air flotation machine is a machine that uses small or tiny air bubbles to float impurities in the medium to the surface. In terms of sewage treatment, except for some sewage with more sand and sewage with heavy mechanical impurities, most sewage contains light suspended particles. The treatment of this kind of sewage is usually achieved by using an air flotation machine. By introducing air bubbles into the water body to make them adhere to the flocs, the overall density of the flocs is greatly reduced, and the rising speed of the air bubbles is used to strengthen the flow rate of the flocs. Use it to float up to quickly realize solid-liquid separation.
