Roots fans have a very important role in wastewater treatment. The following is a summary of their main roles:

1. Providing oxygen for sewage treatment: In the biological treatment process, oxygen in the air is needed to promote the microorganisms to degrade the organic matter in the sewage, thus realizing the purification purpose. Roots fans provide sufficient oxygen to the wastewater treatment system by providing an efficient and stable airflow to ensure a smooth biochemical reaction.
2. Stirring sludge in the tank: The stirring tank is an important part of the sewage treatment system, and the Roots fan is used to generate a strong airflow in the stirring tank, stirring the sludge in the tank, preventing sludge from being deposited and agglomerated, and guaranteeing the uniformity and high efficiency of biochemical reactions.
3. Provide pressure delivery: Wastewater treatment systems need to deliver treated water and gas to the next treatment unit or with the use of other equipment, such as membrane separation, reverse osmosis and other technologies, Roots fans ensure stable and consistent treatment results by providing high-pressure, stabilized air to deliver liquids.
4. Removal of dissolved gases: During the sewage treatment process, dissolved gases such as ammonia and carbon dioxide are contained, and the presence of these gases can affect the treatment effect or even lead to equipment failure. The Roots fan removes the dissolved gases from the sewage by providing sufficient airflow to ensure stable and consistent treatment results.
5. Drying sludge: During the sewage treatment process, a large amount of sludge is produced, which can cause serious pollution to the environment if not handled properly. Roots fans are used to dry the sludge, which reduces the volume while facilitating sludge recycling.

In summary, Roots fans play an important role in wastewater treatment, promoting biochemical reactions and substance transfer by providing efficient and stable airflow, ensuring stable and consistent treatment results, and reducing pollution of the environment.
