Bringing Advanced Air Suspension Blower Technology to Remote Regions
When it comes to wastewater treatment, many facilities in large cities already have access to advanced and energy-efficient technologies. But what about plants located in remote, mountainous regions with difficult logistics and limited infrastructure?
This is exactly the challenge that RAETTS recently faced in Suijiang County, Yunnan Province, China. Despite the geographical barriers, RAETTS successfully installed and commissioned 8 units of 75kW Air Suspension Turbo Blowers for a municipal wastewater treatment plant. This project demonstrates that no matter how remote the location, RAETTS is committed to delivering sustainable solutions.
Why the Upgrade Was Needed
The wastewater treatment plant in Suijiang had been relying on outdated Roots blowers. While they were once the industry standard, Roots blowers are energy-intensive, noisy, and costly to maintain. For a plant operating continuously, the high power consumption and frequent maintenance created both financial and operational burdens.
The plant’s operators decided it was time for a major upgrade. They needed a blower solution that was not only energy-efficient but also reliable, oil-free, and suitable for long-term operation in a remote region with limited access to maintenance resources.
That’s where RAETTS Air Suspension Blowers came in.
The RAETTS Solution: 8x75kW Air Suspension Blowers
RAETTS provided a tailor-made solution: the installation of 8 units of 75kW Air Suspension Blowers to replace the old Roots blower system.
Key advantages of the RAETTS system include:
-
Energy Savings: Each blower operates at around 44kW in real conditions, compared to 75kW or more with Roots blowers. This translates into nearly 40% power reduction. Over the course of one year, the energy savings alone deliver a significant return on investment.
-
Low Maintenance: Unlike Roots blowers that require frequent lubrication and part replacements, RAETTS blowers are oil-free, vibration-free, and designed for minimal maintenance.
-
High Efficiency: With advanced aerodynamics and intelligent controls, the blowers ensure optimal air supply for aeration, maintaining stable dissolved oxygen (DO) levels while avoiding energy waste.
-
Long Lifespan: Designed for 20+ years of operation, the blowers offer reliability that is critical for plants located in regions where service access is limited.
Overcoming Remote Area Challenges
One of the biggest achievements of this project was not only the technical success but also the logistics. Suijiang County is situated in a mountainous area, where transportation and installation can be challenging.
Thanks to careful planning and the dedication of both RAETTS engineers and the local team, all 8 blowers were delivered, installed, and commissioned smoothly. This project reflects RAETTS’s “mission possible” philosophy — ensuring that even wastewater plants in the most remote areas can benefit from world-class energy-saving blower technology.
Sustainable Impact
By replacing the outdated Roots blowers with RAETTS Air Suspension Blowers, the Suijiang wastewater treatment plant has achieved:
-
40% energy reduction, cutting down electricity bills significantly.
-
Improved aeration efficiency, leading to more stable wastewater treatment performance.
-
Reduced operational costs due to less maintenance and higher reliability.
-
Contribution to local sustainability goals, ensuring that clean water treatment supports both the environment and community development.
Conclusion
The Suijiang County project is a perfect example of how RAETTS is enabling municipalities — no matter how remote — to embrace modern, energy-efficient, and sustainable blower technology.
As cities and towns worldwide face increasing pressure to improve wastewater treatment while reducing operational costs, RAETTS Air Suspension Blowers are proving to be a reliable solution.
With projects like this, RAETTS reaffirms its mission: bringing innovation, efficiency, and sustainability to wastewater treatment plants everywhere — even in the most challenging environments.
