STP & ETP Aeration: Best Practices for Twin Lobe Roots Blower Installation and Maintenance

This blog explores the best practices for installing and maintaining twin lobe roots blowers used in STP and ETP aeration systems. Proper blower erection—especially positioning blowers above tanks over 3 meters—helps avoid back pressure, overheating, and noise. The article highlights correct piping layout, avoiding sharp bends and sudden diameter changes, and the importance of routine maintenance. Following these guidelines ensures longer blower life, energy savings, and trouble-free operation. Trust SVBLOWERS for expert solutions in blower installation and service.

Proper installation and regular maintenance of twin/triple lobe Roots blowers are essential for achieving optimum performance in STP, ETP, and industrial aeration systems. At S.V. Engineers, with 20+ years of experience in servicing 7000+ blowers, we consistently identify that improper erection—like installing blowers below tank level or exceeding rated pressure—leads to failures. Common issues include overheating, oil breakdown, and gear damage, all triggered by excessive back pressure (>0.4 kg/cm²) in systems rated for 0.4–0.7 kg/cm². We recommend strict adherence to blower erection do’s—checking free rotation, verifying motor direction, oil level, alignment, silencer fitment, and proper foundation. Avoid bends, pipe size reduction, and low-quality lubricants. Utilize pressure gauges and automatic changeover systems to alternate blower operation based on time or temperature thresholds (e.g., 50°C). Daily and monthly checks of filters, oil, belts, and temperature are vital. For sustained performance, PD blowers are preferred in STP, ETP, aquaculture, and material conveying due to their constant flow delivery, low maintenance, and high durability.
