as Aeration Blowers in Sewage Treatment

Aeration is a core process in sewage treatment, directly affecting the efficiency of organic matter degradation and nitrogen and phosphorus removal. Magnetic Bearing Turbo Blower, as a new type of aeration blower, have gradually replaced traditional roots blowers and centrifugal blowers in sewage treatment plants due to their unique technical advantages. The specific advantages are as follows:

1. High Energy Efficiency, Significantly Reducing Operating Costs

Magnetic Bearing Turbo Blower adopt magnetic levitation bearing technology, which eliminates mechanical contact between the rotor and stator during operation. This design avoids friction loss caused by traditional rolling or sliding bearings, reducing energy consumption by 20% - 40% compared with roots blowers and 10% - 20% compared with traditional centrifugal blowers. In sewage treatment, aeration systems typically account for 50% - 70% of the total energy consumption of the plant. The high energy efficiency of maglev fans can significantly reduce long-term electricity costs, creating considerable economic benefits for sewage treatment plants.

2.Stable Air Supply, Improving Treatment Efficiency

Sewage treatment has strict requirements for aeration stability, as unstable air volume and pressure will affect the activity of aerobic microorganisms and the treatment effect of sewage. Maglev fans are equipped with high-precision frequency conversion control systems, which can realize stepless adjustment of air volume in the range of 20% - 100%. They can quickly respond to changes in sewage water quality and quantity, maintaining stable dissolved oxygen concentration in the aeration tank. In addition, the air supply pressure of maglev fans is stable, with a fluctuation range of less than ±1%, which ensures the uniform distribution of air in the aeration system and fully mixes sewage with oxygen, thereby improving the degradation rate of organic pollutants and the efficiency of nitrogen and phosphorus removal.

3.Low Noise and Vibration, Optimizing Operating Environment

Traditional blowers, especially roots blowers, generate large noise and vibration during operation, which not only affects the physical and mental health of on-site operators but also may cause damage to surrounding equipment and buildings. Maglev fans have no mechanical friction during operation, and the vibration amplitude is less than 0.1mm/s, which is far lower than the national standard for vibration control. The noise level at 1 meter from the fan is only 70 - 80dB(A), which is equivalent to the noise of normal conversation. This low-noise and low-vibration characteristic makes maglev fans suitable for sewage treatment plants located in urban or residential areas, effectively optimizing the on-site operating environment and reducing environmental pollution.

4.Long Service Life and Low Maintenance Costs

 The service life of the core components of maglev fans can reach 15 - 20 years, while the service life of traditional roots blowers is generally 8 - 10 years, and the maintenance cycle is short. In addition, maglev fans are usually equipped with intelligent monitoring systems, which can real-time monitor parameters such as fan temperature, vibration, and current, and issue early warnings for potential faults. This predictive maintenance method can avoid sudden shutdowns caused by equipment failures, reduce the loss of unplanned downtime, and further reduce the overall operation and maintenance costs of the sewage treatment plant.
