Shallow air flotation mainly adopts the principle of dissolved air flotation in the process of working. It is to inject part of dissolved air water into the water to be treated, and use the tiny bubbles released from the dissolved air water to float suspended substances or oil in the water to the surface, so as to achieve the purpose of solid-liquid separation.

The main engine of high efficiency shallow air flotation equipment refers to the separation part of the air flotation equipment, including pool body, scum collecting device, overflow regulating device, rotating water intake and distribution mechanism, etc.

Bubble Formation in Water of Shallow Air Floating Machine

1. The smaller the bubble radius, the greater the additional pressure in the bubble, and the more and more severe the collision probability between the air molecules in the bubble and the bubble film. Therefore, in order to obtain stable micro-bubbles, the strength of bubble film should be ensured.

2. Small bubbles, fast floating speed, little disturbance to the water body, not to crush flocs. It can also increase the probability of collision between bubbles and flocs. However, it is not that the finer the bubbles, the better the bubbles are. The finer the bubbles, the faster the bubbles rise, so the size of the buoyancy pool and the engineering cost are affected. Adding a certain amount of surfactant can effectively reduce the surface tension coefficient of water, enhance the fastness of bubble film, and reduce R.www.khnwatertreatment.com
