Fans in sewage treatment plants generally have three functions:

1. Oxygen supply aeration

2. Mixing water

3. It can be backwashed.

It can increase oxygen for biochemical aerobic bacteria and prevent sedimentation from stirring and backwashing. Due to the large air volume and relatively high pressure requirements, Roots blowers are mostly selected. Rotary blowers and multi-stage centrifugal fans are also useful. Due to their own defects, small pressure flow range and other characteristics, they are somewhat unpopular, and their occupancy is not as high as Roots blowers.

In the sewage plant, Changfeng, Zhanggu and Jingong's Roots blowers and rotary blowers are common, mainly because they have a large number and can stand the test. For specific model selection, the air volume and pressure can be calculated according to the air water ratio, water depth, pipe load, etc., and then the fan type, specific model and motor power can be determined. Roots blower is recommended for sewage treatment, which is convenient for maintenance and low in cost.
