The Role of Aeration Blowers
First and foremost, an aeration blower with precise air volume and pressure plays an essential role in the activated sludge process. Specifically, it continuously infuses air into the sewage and thoroughly oxygenates the water. Consequently, this vigorous agitation accelerates the interaction between oxygen, liquid, and aerobic microorganisms. Ultimately, this process breaks down and oxidizes organic matter in the wastewater effectively.
Two Major Categories of Aeration Blowers
Generally, engineers can choose from two main categories for water treatment:
- Positive Displacement Blowers (PD Blowers): This category includes Rotary blowers and traditional Roots blowers.
- Centrifugal Blowers: This group includes multi-stage centrifugal blowers, single-stage high-speed centrifugal fans, and vortex blowers.
Key Factors in Selecting Water Treatment Blowers
System Applicability & Pressure Resistance
When a sewage treatment system is newly commissioned, the system pressure remains within the design range. Over time, clogged aeration micropores and pipe scaling can increase system resistance.
While traditional Positive Displacement (Roots) blowers provide a constant flow regardless of pressure drops, they are often noisy and energy-intensive. Modern Centrifugal Blowers, equipped with advanced VFD (Variable Frequency Drive) controls, can not only adapt to these pressure changes smoothly but also offer vastly superior efficiency for medium-to-large scale treatment plants.
Energy Efficiency
The energy consumed by aeration blowers can account for 50% to 70% of the total power usage in a wastewater treatment facility. Therefore, selecting high-efficiency centrifugal blowers is the most critical step in reducing your plant’s operational costs (OPEX).
Low Noise Operation
Environmental protection facilities shouldn’t create secondary noise pollution. High-end centrifugal blowers are dynamically balanced (≤ G3.0 grade) and designed with aerodynamic casings to operate significantly quieter than traditional Roots blowers.
Explosion-Proof Requirements
In specific applications involving biogas, chemical engineering, or hazardous environments, explosion-proof blowers are mandatory. Yutong custom-engineers heavy-duty, anti-corrosive, and explosion-proof fans tailored to these severe conditions.
