Air Bearing Turbo Blower Selection for Industrial Wastewater Aeration Projects
An air bearing turbo blower for industrial wastewater aeration is used to supply clean compressed air to aeration tanks, biological treatment basins, MBR systems, oxidation ditches, and industrial wastewater plants that need stable dissolved oxygen control with lower energy consumption.
For many plants, aeration is one of the largest electricity loads. Replacing older Roots blowers or oversized multistage blowers with a correctly selected air bearing turbo blower can reduce operating cost, improve process control, and support long-term wastewater treatment upgrades.
Typical Applications
- Industrial wastewater aeration systems
- Municipal wastewater treatment plant upgrades
- MBR aeration and biological treatment basins
- Food, beverage, textile, chemical, and paper wastewater projects
- Roots blower replacement for clean air aeration
- Energy-saving retrofit projects for existing blower rooms
Selection Parameters
- Required airflow range at minimum, normal, and peak load
- Discharge pressure based on water depth, diffuser resistance, pipe loss, and valve loss
- Ambient temperature, altitude, humidity, and installation room ventilation
- Dissolved oxygen control method and PLC or VFD communication requirement
- Air filter grade, inlet cleanliness, and maintenance plan
- Power supply, voltage, frequency, and local electrical standard
- Noise requirement and blower room layout
- Existing blower model if the project is a replacement
Important Site Conditions
Air bearing turbo blowers are best used for clean air aeration service. The inlet air should be filtered and protected from high dust, corrosive gas, high humidity condensation, and abnormal temperature. The blower room should have enough cooling and service space for maintenance.
Design Options
- Integrated control cabinet with touch screen
- DO control and remote operation interface
- Air filter and silencer package
- Common base and flexible connection
- Multiple blower parallel operation for load matching
- Customized voltage and site layout support

FAQ
Can an air bearing turbo blower replace a Roots blower?
Yes, when the airflow, pressure, operating range, and clean air condition are suitable. Existing pipeline resistance and diffuser condition should be checked before replacement.
What pressure data is needed for selection?
Please provide water depth, diffuser pressure loss, pipe length, valve loss, and required operating pressure range.
Is it suitable for corrosive or dirty gas?
No. Air bearing turbo blowers for aeration should handle clean filtered air. Corrosive, dusty, hot, or wet gas requires a different fan solution.
