Introduction of air flotation machine. The dissolved air flotation (DAF) is mainly used for solid-liquid or liquid-liquid separation. Through the air-dissolving and release system, a large number of fine air bubbles are generated in the water, making them adhere to the solid or liquid particles in the wastewater,so that density is close to that of water, resulting in a state where the overall ...

There are many parameters that affect flotation efficiency. The most important of these parameters is the amount of air drawn into the cell using various pathways for flotation. The process of taking this air from the atmosphere and giving it to water is called aeration. In classical flotation cells, air compressors are used to give air to the ...
