The main purpose of air flotation equipment is to use highly dispersed tiny bubbles as carriers to adhere to hydrophobic particles in sewage, and treat small bubbles and particles as a whole, whose overall density is less than water, and then float to the surface, so as to achieve solid-liquid or liquid-liquid separation. The following is a brief introduction to the working principle of air flotation machine:

1, Breathe air into the water, which will form fine bubbles, so that the small suspended objects in the water adhere to the air bubble, with the bubble floating up to the surface, forming scum, to remove suspended objects in the water and improve the water quality.

2. Influencing factors of air floatation and measures to improve the effect of air floatation: the smaller the diameter of air floatation and the more air floatation, the better the effect. Inorganic salts in water can accelerate the rupture and merger of bubbles and reduce the effect of air flotation. Adding flocculant can promote the aggregation of suspended matter and make it stick to the air bubble and float up. Flotation agent can be added to change the surface of hydrophilic particles into hydrophobic substances and stick to the air bubble and float up with the air bubble.
