Sewage treatment project we generally use Roots fan effect?

In sewage treatment projects, the use of Roots fans has the following effects:

First, performance characteristics

Stable gas supply

The Roots fan provides a stable air flow and pressure, ensuring a stable supply of oxygen for microorganisms during the wastewater treatment process, which is essential to maintain the normal operation of the biochemical treatment system. For example, in the activated sludge treatment process, the stable gas supply can make the microorganisms in the activated sludge fully contact with the organic matter in the sewage, and carry out an effective biochemical reaction.

Its air volume is not affected by pressure changes, and even when the system resistance changes, it can maintain a relatively stable output to ensure the continuity and stability of the sewage treatment process.

Higher pressure

Roots fans can produce high pressure to meet the needs of different sewage treatment processes. For example, in processes that require deep aeration, high pressure can diffuse air more deeply into the wastewater, improving the efficiency of oxygen transfer.

For large wastewater treatment plants or where air needs to be transported over long distances, the high pressure characteristics of Roots fans ensure the smooth delivery of air to all treatment links.

2. Operation reliability

Simple and strong structure

The structure of Roots fan is relatively simple, mainly composed of shell, impeller, gear and other components. Most of these components are made of high-strength materials, with good wear resistance and corrosion resistance, and can operate stably in harsh sewage treatment environments for a long time.

Its simple structure also makes maintenance and repair relatively easy, reducing equipment maintenance costs and downtime.

Long operating life

The design life of Roots fan is long, generally up to more than 10 years. Under normal use and maintenance, Roots fans continue to provide a reliable air supply for sewage treatment projects.

Good quality and stable performance make Roots fan in the sewage treatment industry has been widely used.

3. Wide range of application

Suitable for different scale sewage treatment projects

Whether it is a small sewage treatment station or a large sewage treatment plant, Roots fans can provide the right air volume and pressure according to the actual demand. For small sewage treatment projects, small Roots fans can be selected to meet the basic aeration needs; For large sewage treatment plants, large-scale air supply can be achieved by running multiple Roots fans in parallel.

Its flexible configuration can adapt to the needs of different scale sewage treatment projects.

Suitable for a variety of sewage treatment processes

Roots fan has a wide range of applications in various sewage treatment processes, such as activated sludge method, biofilm method, oxidation ditch method and so on. In different processes, Roots fans can adjust the air volume and pressure according to process requirements to provide a suitable growth environment for microorganisms.

For example, in the biofilm process, Roots fans can evenly distribute air on the surface of the biofilm through microporous aerators to promote the growth and metabolism of the biofilm.

Fourth, economic cost considerations

Low initial investment cost

The initial investment cost of Roots fans is relatively low compared to other types of fans. Its simple structure, mature manufacturing process and fierce market competition make the price relatively close to the people.

For some sewage treatment projects with limited budgets, Roots fans are a more economical choice.

Low operating costs

Roots fans have relatively low energy consumption and high energy efficiency. In the long run, the energy consumption cost of sewage treatment project can be reduced.

In addition, the maintenance cost of Roots fans is also relatively low, reducing the overall operating cost of the equipment.

In summary, the use of Roots fan in sewage treatment projects has the advantages of stable gas supply, high pressure, reliable operation, wide application range and low economic cost. However, when selecting Roots fans, it is also necessary to comprehensively consider factors such as specific sewage treatment process requirements, project scale and budget to ensure that the most suitable equipment is selected.
