The past decade has ravaged Florida from its panhandle to the Keys, with five major hurricanes. In 2010, the city of Tallahassee determined that, for several of its master sanitary pump stations, adequate backup pumping capacity was necessary to continue basic services during the types of power outages that the hurricane seasons of previous years had brought. As a result, the city of Tallahassee ...

They're lurking in the sewers, rolling onwards, growing larger... Fat is a menace to pumping stations. Often forming balls reaching the size of footballs, they can mass in their hundreds, clogging up vital equipment as they float to the surface. The result? Blockages, toxic gases and, ultimately, expensive breakdowns. But they've met their match with a revolutionary new bio-technology - The ...

None of the problems associated with VFD exist when using a Cycle Stop Valve for control. With a CSV, the motor is always spinning at full RPM, but the amps are reduced similarly to varying the speed. When the motor is spinning at full speed, the cooling fan always provides adequate cooling. Spinning at full speed also means there are no problems with resonance frequency vibrations. Running on ...

Traditionally pump intake hydraulics have been investigated using scale physical hydraulic models. Computational fluid dynamics (CFD) is a rapidly improving technology that in some cases can be used as a cost or time effective alternative to traditional physical model methods for evaluation of pump intake hydraulics. This paper presents a case study on the use of CFD modeling to re-evaluate and ...
