The role of Roots blower in sewage treatment and the role of Roots blower in sewage aeration!

In this chapter, we will talk about the role of Roots blower in sewage treatment. Roots blower mainly plays the role of aeration. It can effectively mix the air in the aeration tank by compressing and conveying the air from the bottom of the aeration tank.

Aeration can increase the oxygen content in water, provide a suitable environment for aerobic bacteria, and facilitate the cultivation of aerobic bacteria. It can also provide air source for aeration tank and oxidation tank.

In small and medium-sized sewage treatment plants, three leaf roots blowers are commonly used, mainly because the three leaf blowers have large air output and stable operation. So let's recommend a good brand of Roots blower!

In the sewage treatment plant, the energy consumption of the sewage aeration fan accounts for about half of the total energy consumption, so the selection of the appropriate aeration fan plays a vital role in saving the operation cost of the enterprise. However, this link is often the most troublesome for customers, because they are not professional in the selection. So today we will take a look at whether Roots blower or centrifugal blower is ideal in the mainstream process of sewage treatment.

We all know that Roots blower and centrifugal blower are the two most common types of water treatment fans, and they are different in use.

Roots blower is a constant flow fan. The main working parameter is the air volume. The output pressure changes with the change of pipe and load, and the air volume changes little. It can be called a positive displacement fan. The air volume transported is proportional to the number of revolutions, and the gas is transported from the suction side to the discharge side.

The centrifugal fan is a constant pressure fan, and the main working parameter is the air pressure. The output air volume changes with the change of pipe and load, and the air pressure changes little. Therefore, in terms of pressure, Roots blower is higher than centrifugal blower. If higher pressure blower is required for sewage treatment, Roots blower is generally selected. In case of deep water and high pressure, aeration volume can be guaranteed. If the load requires constant pressure effect, centrifugal fan shall be used.

When it comes to the selection of aeration fans, we should finally consider our own situation. The first thing customers need to consider is the scale of the project treatment. If it is a small sewage station, it is enough to choose Roots fans. But generally, large and medium-sized sewage plants choose more centrifugal fans. In the end, it is still a case by case analysis.
