How to calculate the air volume of Roots blower in the aeration tank of WWTP?

The following factors need to be considered in the calculation of Roots blower air volume in the aeration tank of the sewage treatment plant: Shandong Xinqianshun Machinery will give you a detailed introduction!

The scale and treatment requirements of the sewage treatment plant: these factors determine the required air volume and pressure.

Volume and shape of aeration tank: These factors affect the distribution and flow of gas in the tank.

Oxygen demand: calculate the required air volume according to the oxygen demand of biochemical reaction.

The specific calculation method can be referred to the product sample or technical manual provided by the manufacturer of Roots blower. Generally speaking, the following steps can be followed:

The oxygen demand of the aeration tank can be determined by measuring the dissolved oxygen concentration in the tank.

According to the shape and size of the aeration tank, calculate the volume of the aeration tank.

Calculate the required air volume according to the volume and oxygen demand.

Select appropriate Roots blower model and power according to air volume and pressure requirements.

It should be noted that the impact of environment, climate, altitude and other factors on air density and oxygen content, as well as the impact of water quality, climate temperature and other factors on the performance of the blower should also be considered in actual use, so further conversion and calibration are required.
