In the process of flotation of the air flotation machine, the appropriate coagulant should first be added to the sewage, which can not only change the hydrophilic properties of the suspended particles in the sewage, but also flocculate the fine particles in the sewage into larger flocs. It is easier to adsorb trapped air bubbles and accelerate the floating of particles.

Secondly, the flotation agent is also one of the chemical solvents used in air flotation. When the polar group of the flotation agent is adsorbed on the surface of the hydrophilic suspended particles, the non-polar group will face the water, promoting the hydrophilicity The hydrophobic substance is converted into a hydrophobic substance, which further adheres to the fine air bubbles to form a stable scum layer.

In order to improve the water tightness of the surface of suspended particles during the air flotation process, an appropriate amount of coagulation aid can be added to the sewage, which has a significant effect on improving the floatability of the particles; there are also inhibitors, which can temporarily or permanently inhibit certain substances. The flotation performance, but there is no impediment to the removal of suspended particles.

There is also a regulator, which can be used to adjust the PH value of sewage, which plays a key role in improving and improving the dispersion of air bubbles in water, and at the same time, it can also improve the adhesion between suspended particles and air bubbles, so that the air flotation effect is better. .
