According to the working principle, air flotation can be divided into many categories, but their functions are similar. Air flotation equipment is currently used in water supply, industrial wastewater and urban sewage treatment. Compared with other solid-liquid separation equipment, air flotation equipment has the characteristics of less investment, extremely small footprint, high degree of automation, and convenient operation and management. In practice, targeted selection and use should be made according to the characteristics of wastewater treatment process, water quality and quantity of wastewater.

1. Advection pressurized dissolved air flotation machine: The dissolved air method is pressurized jet (the interior is not easy to be blocked). This type of air flotation is currently widely used in China. The structure is relatively simple, and the on-site operation and installation are relatively simple. It is suitable for pretreatment and partial follow-up treatment of various industrial wastewater and municipal wastewater.

2. Vertical flow pressurized dissolved air flotation machine: The dissolved air method is pressurized jet. This type of air flotation is currently used very rarely in China. Due to its complex structure, high height, and difficult operation and maintenance, Therefore, compared with the advective pressurized dissolved air flotation effect, the effect is greatly reduced, and there is only an advantage in the floor space.

3. High-efficiency shallow air flotation machine: The dissolved air method is pressurized jet. This type of air flotation is also widely used in China, especially in the paper industry. Other industries have also begun to use it slowly in recent years. The content is relatively high, and there are not many good ones in China at present (it is suitable for projects with large water treatment volume, and GF type dissolved air flotation is recommended for water volume less than 100T/H).

4. Vortex concave air flotation machine: The dissolved air method is the high-speed rotation of the impeller and the negative pressure suction to generate micro-bubbles. This type of air flotation is widely used in China, mainly in the pretreatment section of oily wastewater, and the effect is better.

5. Multi-stage air flotation machine: The dissolved air method is pressurized jet, and this type of air flotation is used more, which is characterized by small footprint, high processing capacity, and large impact load resistance.

6. Experimental air flotation: It is mainly used for qualitative and quantitative fly analysis of the feasibility of air flotation of various wastewaters.

7. Micro air flotation: mainly used for wastewater treatment with small water volume.
