Energy-Saving Retrofit with RAETTS Portable Air Bearing Blower in Thailand
Wastewater treatment is a critical challenge for industries worldwide, especially for energy-intensive sectors such as aluminum manufacturing. As sustainability and cost reduction become increasingly important, companies are looking for innovative ways to upgrade their existing systems. Recently, RAETTS successfully delivered a 15 kW portable air bearing blower to a Thai aluminum plant, demonstrating how cutting-edge blower technology can reduce energy consumption while improving system performance.
The Challenge: High Energy Costs in Wastewater Aeration
Aeration is the most energy-demanding process in wastewater treatment. Traditional blowers, often oversized and outdated, consume far more energy than necessary. For small to medium wastewater treatment plants, finding a balance between sufficient aeration, compact equipment, and low operational cost can be especially difficult.
The aluminum factory in Thailand faced this exact challenge. Their wastewater treatment facility required stable aeration but was limited in space and wanted to reduce energy costs from traditional roots blowers. The management sought a retrofit solution that could be installed quickly without disrupting ongoing operations.
The Solution: RAETTS Portable Air Bearing Blower
RAETTS introduced its Konrad portable series air bearing blower, designed specifically for compact, flexible, and energy-efficient wastewater applications.
-
Delivered Equipment: 15 kW portable air bearing blower
-
Operating Performance: Actual power consumption only 7 kW while meeting aeration demand
-
Series Range: 7.5 kW – 22 kW, with airflow from 7–24 m³/min and pressure range 40–80 kPa
This series is engineered to help small wastewater plants or industrial facilities with limited space achieve both high efficiency and low noise, while ensuring long-term reliability thanks to oil-free, low-maintenance design.
Key Benefits Observed
-
Visible Energy Savings
The retrofit demonstrated a 53% reduction in power consumption (from 15 kW rated to 7 kW actual). This translates into significant annual electricity savings and faster return on investment. -
Compact and Portable Design
The portable series blower has a small footprint, making it ideal for facilities where installation space is limited. The plug-and-play design also allows for quick retrofitting. -
Stable Aeration Performance
Despite lower power consumption, the blower provided sufficient airflow and pressure to maintain effective wastewater aeration, ensuring compliance with environmental standards. -
Low Maintenance, High Reliability
As an oil-free blower with advanced air bearing technology, downtime and maintenance costs are minimized. This is a significant advantage compared to traditional roots blowers or screw compressors.
Why RAETTS Konrad Portable Series is Ideal for Small Wastewater Plants
The Thai case highlights why the Konrad portable series is gaining attention across various industries:
-
Suitable for industrial wastewater retrofits where energy savings are a priority
-
Perfect for small municipal plants with limited installation space
-
Ideal for temporary treatment stations requiring flexibility and portability
-
Provides low noise, clean air, and sustainable operation
With power options ranging from 7.5 kW to 22 kW, RAETTS ensures that different plant capacities and aeration requirements can be matched precisely, avoiding over-sizing and energy waste.
Looking Ahead: A Smarter Way of Wastewater Treatment
This successful project in Thailand demonstrates how advanced blower technology can transform wastewater treatment from an energy-heavy burden into a sustainable and cost-efficient process.
By choosing RAETTS, industries benefit from:
-
Reduced operational costs through lower power consumption
-
Improved environmental compliance with stable aeration
-
Future-ready design that supports sustainable development goals
Conclusion
The 15 kW RAETTS portable air bearing blower installation in a Thai aluminum factory’s wastewater plant is a clear example of how small but smart upgrades can deliver big results. With actual consumption of only 7 kW, this project highlights the energy-saving advantage, compact design, and reliable performance of RAETTS Konrad series.
For industries seeking to modernize their wastewater treatment without large investments or space expansion, RAETTS portable series provides the perfect solution.
