Case Study: Xuzhou Wastewater Treatment Plant Upgrades to RAETTS Maglev Turbo Blowers
A New Era of Energy Efficiency in Municipal Wastewater Treatment
As cities across China accelerate their journey toward smarter and greener infrastructure, Xuzhou High-Tech Zone Wastewater Treatment Plant has taken a decisive step toward sustainability. The plant recently installed three 55kW RAETTS Maglev Turbo Blowers, replacing conventional blowers with state-of-the-art magnetic levitation technology — and the results speak for themselves.
Each RAETTS Maglev blower operates at just 44kW during normal operation, achieving over 20–30% energy savings while delivering consistent, high-efficiency aeration performance. This upgrade not only reduces operating costs but also contributes to long-term carbon reduction goals for municipal treatment systems.
⚙️ Intelligent Design for Precision and Reliability
The new system features smart control modes that allow precise adjustment and monitoring across multiple parameters — including current, rotational speed, pressure, airflow, and dissolved oxygen (DO).
This intelligent feedback system ensures that the blowers automatically adapt to real-time process demands, optimizing energy usage and maintaining stable dissolved oxygen levels throughout the aeration tanks.
One of the standout advantages of RAETTS Maglev Turbo Blowers is their ability to support frequent start-stop operations without mechanical wear. The contact-free magnetic bearings eliminate friction, oil, and mechanical loss — resulting in a truly maintenance-free operation with minimal downtime.
💨 From Traditional Roots Blowers to Maglev Efficiency
Before the upgrade, the plant relied on traditional Roots blowers — a technology that, while reliable, suffers from high energy consumption, loud noise, and costly maintenance.
Roots blowers typically:
-
Consume 100% baseline power
-
Require regular oil, belt, and gear maintenance
-
Generate over 110–120 dB of noise and high vibration
-
Have a lifespan of around 10 years
By contrast, RAETTS Maglev Turbo Blowers provide:
-
30–40% lower power consumption (payback period: 1–2 years)
-
Near-zero maintenance costs (only air filter replacement)
-
Low noise at 80–85 dB, with no need for special foundations
-
Over 20 years of service life, thanks to contact-free bearings
This technological leap means lower operational expenditure (OPEX), fewer maintenance shutdowns, and a quieter, cleaner working environment — all while meeting increasingly strict energy standards in wastewater treatment.
🌱 A Step Toward Smarter Water Management
The Xuzhou High-Tech Zone project demonstrates how advanced technologies like RAETTS Maglev Turbo Blowers can redefine operational efficiency for wastewater treatment plants.
With rising electricity prices and sustainability targets, the choice of blower technology has become a critical factor in plant performance and profitability.
RAETTS continues to work closely with engineering teams, EPC contractors, and environmental authorities to promote high-efficiency aeration solutions that reduce costs and emissions.
🔍 Thinking About an Upgrade?
If your wastewater or ETP plant still relies on traditional Roots blowers, it might be time to consider a smarter alternative.
RAETTS Maglev Turbo Blowers combine permanent magnet synchronous motors (PMSM), aerospace-grade impellers, and intelligent DO control — offering unmatched reliability, savings, and environmental benefits.
