Application of Three-Lobe Roots Blowers in Large-Scale Wastewater Treatment Plants in the Core Area of the Yangtze River Delta


A benchmark large-scale municipal wastewater treatment plant in a core city of the Yangtze River Delta with a population of over ten million consistently ranks among the top tier of China’s municipal wastewater treatment sector, thanks to its industry-leading process standards and highly refined operations and maintenance capabilities. In the critical aeration and oxygen-supply stage, the plant leveraged its expert judgment to select Nantong Rongheng Environmental Protection’s three-lobe Roots blowers, thereby establishing a robust power foundation for efficient biochemical treatment. 
The Nantong Rongheng Environmental Protection three-lobe Roots blower features stable, low-noise operation and precise airflow output. Its integrated air-and-water cooling design enables automatic switching from air cooling to water cooling on-site when operating pressure rises, ensuring excellent adaptability to harsh conditions such as overpressure and overheating. This eliminates the need to replace equipment due to such issues, thereby reducing costs and delivering strong economic benefits.
