The surface of the suspended matter in air flotation is hydrophobic and hydrophilic, and the hydrophobic surface is prone to adhering bubbles, so the air flotation method can be used, and the hydrophilic particles can be properly applied to chemicals during use. After treatment, it can be directly converted to hydrophobicity.

When air flotation is treated in water, coagulants are often used, which can directly consolidate colloidal particles into flocs. Such flocs have a certain network structure and are very prone to trapped air bubbles, which can greatly improve the efficiency of air flotation. The air flotation efficiency of the product, if there is a surfactant in the water, such as a frequently used detergent, it can directly form its foam, and it will also attach suspended particles to rise together.

In fact, the air flotation method is also known as the dispersed air method. It is mainly to effectively set its micropores at the bottom for effective diffusion. The compressed air in the equipment will escape directly on the board or tube surface in the form of smiling bubbles. The impeller is installed out of the water and at the bottom of the pool, with the axle perpendicular to the water surface.
