Guangdong Wastewater Plant Saves 30% Energy with KONRAD Portable Air Bearing Blowers
Project Background
In early 2025, a municipal wastewater treatment plant in Guangdong Province faced two urgent challenges: rising electricity costs and limited available space for equipment upgrades. The plant was operating with aging Roots blowers, which consumed high amounts of energy and required frequent maintenance.
With energy prices climbing and environmental regulations becoming stricter, the plant’s management sought a more efficient and compact solution that could be installed quickly without major structural changes.
RAETTS Solution
After an on-site evaluation, RAETTS recommended replacing the existing Roots blowers with two KONRAD portable air bearing blowers, with a total installed power of only 30 kW. The KONRAD portable series is specifically designed for projects requiring:
-
Compact footprint for easy installation in space-limited facilities
-
High efficiency for reduced operating costs
-
Low maintenance through oil-free, contact-free air bearing technology
Installation & Commissioning
The upgrade process was completed in just a few days:
-
Delivery & Positioning – Due to the KONRAD’s compact design and lighter weight, no major lifting equipment or structural modifications were needed.
-
Connection & Setup – The blowers were connected to the existing pipework with minimal adjustments.
-
On-Site Testing – Performance was monitored through real-time data logging, including flow rate, pressure, and power consumption.
Performance Results
The real-world results were impressive and immediately visible:
| Parameter | Old Roots Blower | KONRAD Portable Air Bearing Blower | Improvement |
|---|---|---|---|
| Total Installed Power | 45 kW | 30 kW | -33% |
| Daily Energy Consumption | High | ~30% lower | |
| Noise Level | 85 dB | < 75 dB | Quieter |
| Maintenance Frequency | High | Minimal | Reduced downtime |
Key benefits observed:
-
~30% Energy Savings — translating to thousands of RMB saved in electricity bills annually.
-
Compact Design — freed up valuable floor space for other operations.
-
Quiet Operation — reduced noise impact for both operators and surrounding areas.
-
Low Maintenance — air bearing technology eliminates the need for lubrication and frequent part replacement.
Why KONRAD Portable Air Bearing Blowers?
The KONRAD portable series offers the same high efficiency as RAETTS’ larger maglev turbo blowers but in a smaller, more flexible package:
-
Starting power from 7.5 kW — ideal for small and medium wastewater plants.
-
Plug-and-play installation — fast deployment without complex civil works.
-
Long service life — designed for durability with minimal wear.
Customer Feedback
According to the plant’s operations manager:
“The KONRAD blowers fit perfectly into our existing setup. Not only did we reduce our energy consumption by about 30%, but we also saved space and reduced noise in the working area. The quick installation meant no disruption to our daily operations.”
Conclusion
This Guangdong wastewater treatment plant’s successful upgrade demonstrates how modern air bearing blower technology can deliver substantial energy savings, operational efficiency, and environmental benefits — all within a compact and portable design.
For plants facing similar challenges — high energy costs, limited space, and demanding maintenance schedules — the KONRAD portable air bearing blower series provides a proven, cost-effective solution.
