RAETTS Air Bearing Blowers Help Zhongshan Huaxing Power Plant Cut Energy by 35% in Wastewater Treatment

RAETTS Air Bearing Blowers Helps Zhongshan Huaxing Power Plant Achieve 35% Energy Savings in Wastewater Treatment

In an era where industries are striving for energy efficiency and sustainable operation, RAETTS once again proves the power of innovation.
Recently, RAETTS successfully completed a blower retrofit project for Zhongshan Huaxing Power Co., Ltd., installing six 150kW air bearing blowers to replace traditional Roots blowers used in the wastewater treatment section.

💨 From Traditional to Intelligent: A Major Step Forward

Before the upgrade, the wastewater treatment plant relied on multiple 150kW Roots blowers. Although robust, they consumed significant energy and required regular oil maintenance.
Through a detailed technical assessment, RAETTS proposed to adopt its air bearing turbo blowers, known for high efficiency, oil-free operation, and intelligent control.

After installation and commissioning, each blower’s actual operating power stabilized around 92kW — representing a 35% reduction in energy consumption compared with the old system.
For an operation running 24/7, that’s a massive saving of approximately 250,000 kWh per year per unit, translating into tens of thousands of dollars in electricity savings annually.


⚙️ Reliable Performance, Zero Maintenance

RAETTS air bearing blowers operate without lubricating oil, thanks to advanced air foil bearing technology.
This design not only eliminates the need for oil replacement but also removes contamination risks to the wastewater treatment process.

Furthermore, the blowers are equipped with:

  • Permanent Magnet Synchronous Motors (PMSM) for top-tier efficiency

  • Three-dimensional flow impellers made of aerospace-grade aluminum

  • Smart control system capable of precise adjustments of air volume, pressure, and dissolved oxygen levels

The result is stable aeration, reduced operating noise (below 75 dB), and a cleaner, safer working environment.

💰 Return on Investment Within One Year

With a 35% reduction in power consumption and minimal maintenance costs, the project’s payback period is less than one year.
After that, every month represents pure savings for the plant.

Besides direct financial benefits, the upgrade also improves operational stability and environmental compliance, supporting Huaxing Power’s sustainability goals and aligning with China’s push for green manufacturing.

🧠 Voices from the Field

The project’s engineering supervisor from Huaxing Power shared:

“RAETTS provided not just a product, but a long-term solution.
Our operators immediately noticed the difference — quieter, smoother, and much easier to manage.”


🌱 A Step Toward Greener Industry

For RAETTS, every successful retrofit is another milestone in driving industrial sustainability.
From municipal wastewater treatment plants to industrial ETPs, RAETTS air bearing and maglev turbo blowers are helping businesses cut energy use by 30–40%, reduce O&M costs, and achieve long-term reliability.

Even in the demanding power generation sector, where operational continuity is crucial, RAETTS solutions deliver exceptional stability and efficiency — ensuring every cubic meter of air contributes to a cleaner, greener future.
