Introduction In municipal wastewater lift stations and industrial effluent sumps, the submersible pump is often the most critical, yet least visible, asset. Because these units operate beneath the liquid surface, visual inspection during operation is impossible. Consequently, engineers and operators must rely heavily on external data and performance anomalies to identify impending failures. A surprising […]
The President Street Water Reclamation Center (WRC) stands as the cornerstone of wastewater infrastructure for the City of Savannah, Georgia. As the largest facility operated by the Cityβs Water Resources Department, it is permitted to treat a design flow of 27 million gallons per day (MGD).

INTRODUCTION One of the most persistent errors in municipal and industrial fluid handling involves applying centrifugal pump logic to positive displacement equipment. Engineers often approach pump curves expecting a single line intersecting a system curve, but when faced with an Air-Operated Double Diaphragm (AODD) performance chart, they encounter a complex grid of air pressures, air […]
