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

The calculation of Roots blower air volume in the aeration tank of the sewage treatment plant can generally be carried out through the following steps:

1. Determine the design parameters of the aeration tank, including the volume (V) of the aeration tank, dissolved oxygen requirements, aeration time, etc.

　　2. Calculate the required total aeration rate (Q) according to the design parameters and process requirements. The total aeration volume refers to the amount of oxygen provided in the aeration tank within a unit time, which is usually calculated based on the standard volume flow, and the unit is m3/h.

3. Obtain the performance parameters of Roots blower, including the rated air volume and rated power of the blower.

4. According to the total aeration volume (Q) required and the rated air volume of the blower, calculate how many blowers are required. Generally, the following formula can be used for calculation:

Number of blowers required=total aeration rate (Q)/rated air volume of blowers

5. Estimate the total power required according to the rated power and actual operation status of the blower.

Please note that the above is an overview of the general calculation method, and the specific calculation needs to be adjusted according to the actual situation and equipment parameters. In addition, since we do not know the specific situation, the above answers are for reference, and the specific operation still needs to be carried out according to the actual situation and relevant specifications.
