Micro-high speed and high efficiency airfoil bearing turbo blower (referred to as air turbo blower) is increasingly widely used in the sewage treatment industry, its core technology through air suspension bearing to achieve contactless operation, combined with intelligent control system, significantly improve the efficiency of sewage treatment and reduce energy consumption.

I. Core application scenarios

a. Oxygen for aeration

By transporting compressed air to the aeration tank, the airfoil bearing turbo blower increases the concentration of dissolved oxygen in the water and promotes microbial degradation of organic matter. Its precise air volume adjustment ability (such as adjusting the speed through the inverter) can dynamically match the needs of different working conditions, avoiding the energy waste caused by excessive aeration of traditional equipment.

b. Mix and stir

Through the air bubble and water flow disturbance, the airfoil bearing turbo blower can evenly disperse the suspended matter in the sludge and enhance the solid-liquid contact efficiency. For example, in the MBR (membrane bioreactor) process, its efficient mixing capability reduces membrane contamination and extends equipment life.

c. Backwash and sludge treatment

In the backwash phase of the filter or membrane assembly, the air float blower provides high pressure air to wash away impurities and restore the efficiency of the treatment unit. In one case, the  airfoil bearing turbo blower replaced the traditional Roots blower, the backwash efficiency was increased by 30%, and the noise was reduced to less than 80dB.

II.Technical advantage and energy-saving effect

1. Noise level below 80 dBA, ensuring quiet operation, much more environmentally friendly.  

2. Significant energy-saving effects:  

 - 25%-50% more energy-efficient than Roots blowers.  

 - 20%-40% more energy-efficient than ring blowers.  

 - 20%-30% more energy-efficient than screw blowers.  

3. Oil-free medium, no need for lubrication oil, resulting in low operating costs.  

4. Whole set skid-mounted design, independent Siemens PLC control, Siemens touchscreen, and high level of intelligence.  

5. High-precision integration, compact size, occupying smaller space.  

6. Maintenance-free, only requires filter replacement every three months, with each filter costing less than 50 euros, ensuring low maintenance costs. Filters can be replaced during operation without the need for shutdown.  

7. Can be set for timed start and stop.  

8. Two mode options: speed mode and flow mode.  

9. Air foil bearings with a lifespan of up to 20 years, ensuring long-term operation without mechanical wear and no decrease in efficiency.  

10. Utilizes aerospace materials, five-axis machining for high-precision ternary flow impellers, and direct drive by high-speed permanent magnet motors, achieving speeds up to 30,000 RPM with no energy efficiency loss and motor efficiency as high as 98%.  

11. 12-month warranty since the customer receives the product, with a replacement-only policy during the warranty period.  

12. Domestic screens allow for remote monitoring via computer or mobile phone anytime, anywhere.  

13. OEM services are available at an additional 20% cost.  

14. There's a warehouse and after-sale service center in Gdansk, Poland, allows for quick replacement and installation, ensuring short delivery times.
