At present, the air suspension blower can only achieve positive pressure, that is, blowing air, but not inhaling. Therefore, this equipment is often used for aeration, and its main applications are in the fields of sewage treatment aeration and aquaculture aeration.

Sewage aeration mainly rotates the impeller through the air suspension blower to generate gas, and through the method of aerating the water, the gas and the sewage are brought into contact to remove harmful gases such as nitrogen dioxide and odor in the water, increase the concentration of oxygen, and accelerate the degradation of aerobic microorganisms. 

The current social environment is energy conservation and emission reduction. The notice of the national urban sewage treatment and utilization facility construction plan also mentioned that some of the sewage treatment facilities that have been built should be upgraded to improve the ability to reduce major pollutants.

Many improved sewage treatment plants lack phosphorus and nitrogen removal functions and do not have the ability to biologically treat them. They mainly transform sewage treatment plants in developed areas, major water sources, and major river basins.

The air suspension blower can be used in new construction or renovation projects of sewage treatment plants. It has the advantages of energy saving and environmental protection, and can replace the Roots blower. The country is also calling for the upgrading of sewage treatment facilities, so the air suspension blower in the sewage treatment plant will be used in the future.
