Is it good to use a Roots blower for aeration? Advantages and disadvantages of in-depth analysis**
**Keywords: Is it good to use Roots blower for aeration**
**1、 Technical characteristics of Roots blower**
Roots blower is a positive displacement fan that pushes gas through the engagement of two parallel rotors, providing a constant flow rate and strong pressure adaptability (0.1-1.2 bar).
**2、 Advantages in aeration applications**
1. * * High pressure capability * *: Suitable for deep water aeration (such as water depths above 5 meters), while rotary type may have insufficient pressure;
2. Durability: The cast iron body is corrosion-resistant and has a lifespan of over 10 years;
3. * * Stable flow * *: not affected by pressure fluctuations in the pipeline network, suitable for scenarios with large water quality fluctuations.
**3、 Potential drawbacks**
-* * Noise issue * *: It can reach 90dB or more and requires the installation of a muffler;
-High energy consumption: Compared to magnetic levitation fans, the energy efficiency is about 10-15% lower;
-* * Maintenance cost * *: The gearbox requires regular replacement of lubricating oil.
**4、 Suggested Applicable Scenarios**
-* * Recommended use * *: High pressure demand scenarios such as chemical wastewater and high concentration organic wastewater;
-Not recommended: Urban sewage treatment plants that are sensitive to noise (unless they have sound insulation measures).
**Data support: After a paper mill switched to Roots blowers, the aeration uniformity improved by 30%, but the electricity bill increased by 8%.
