1. Wastewater Aeration: In the biological treatment process, Roots blowers are used in the aeration system to provide oxygen supply to microorganisms for biodegradation of organic matter in wastewater by compressing and injecting air into the aeration basin or aeration tank. This helps to promote the growth and metabolic activity of the microorganisms and accelerates the sewage treatment rate.
2. Sludge agitation and mixing: In the sewage treatment process, Roots blowers can be used to agitate and mix sludge. By generating air bubbles and water flow, Roots blowers can suspend and evenly mix sludge, preventing sludge deposits and lumps and improving sludge treatment.
3. Sludge Dewatering: In the final stage of wastewater treatment, sludge needs to be dewatered to reduce its volume and moisture content. Roots blowers can be used in sludge dewatering equipment to dewater sludge by providing gas pressure to induce evaporation and volatilization of water in the sludge.
4. Sewage Lifting and Conveying: In the sewage treatment process, there is a need to lift the sewage from a low place to a high place or to convey the sewage to a distant treatment equipment. Roots blowers can be used to provide air pressure to propel the flow of sewage and realize sewage lifting and conveying.
5. Wastewater Odor Control: Wastewater treatment processes can produce malodorous odors that can affect the surrounding environment and the health of workers. Roots blowers can be used in odor control systems to improve the working environment by providing airflow and ventilation to expel or treat malodorous odors.

Roots blowers are very important in wastewater treatment. They play a key role in wastewater aeration, sludge mixing and blending, sludge dewatering, wastewater lifting and conveying, and wastewater odor control, improving the efficiency and quality of wastewater treatment.
