Shallow air flotation mainly produces a large number of micro-bubbles in water, so that air can attach to suspended particles in the form of highly dispersed micro-bubbles, resulting in a state of less density than water, using buoyancy principle to float it on the water surface, thus realizing solid-liquid separation of water treatment equipment.

Superiority of shallow air flotation

1. Large capacity, high efficiency and less land occupation.

2. The process and equipment are simple, easy to use and maintain.

3. Sludge bulking can be eliminated.

4. It can significantly reduce the floating SS and sinking SS.

5. Aeration into water during air flotation has obvious effect on removing surfactant and odor in water. At the same time, aeration increases dissolved oxygen in water and reduces some insoluble COD, which provides favorable conditions for subsequent treatment.

Shallow air flotation is effective for low temperature, low turbidity and algae-rich water sources. The best effect can be achieved by air flotation.

The advantages of shallow air flotation lie in its advantages of low investment, minimal floor area, high automation and convenient operation and management.www.khnwatertreatment.com
