  • Numerical study of flow parameters and entropy generation on a centrifugal fan

    A whole backward-inclined centrifugal fan has been simulated using three-dimensional elliptic governing equations to calculate the flow field and entropy generation. Dissipation term in the energy equation is not neglected and used to calculate the generation of entropy. The standard k-ε turbulence model has been adopted and the numerical model has been validated by experimental results. It is ...

  • Tri-Mer Fan / Separator Chosen by Boeing

    Boeing Helicopter, Ridley Park, Pa., manufactures specialty aircraft components, for the Chinook (CH-47).  The facility also repairs and overhauls aircraft, including the entire US Chinook fleet. In June, 2003, Boeing contacted with Walgren Company (Grand Rapids, MI) for manufacture of an alodize line.  The 5-stage alodize system was specified with a Tri-Mer “Fan/Separator” to handle ...

  • Case study of odor and indoor air quality assessment in the dewatering building at the Stickney Water Reclamation Plant

    Indoor air quality (IAQ) and odors were determined using sampling/monitoring, measurement, and modeling methods in a large dewatering building at a very large water reclamation plant. The ultimate goal was to determine control strategies to reduce the sensory impacts on the workforce and achieve odor reduction within the building. Study approaches included: (1) investigation of air mixing by ...

  • VFD for pumping systems

    Pumping systems account for nearly 20% of the world's electrical energy usage. In some process plants, the VFD for pumps and fans together account for between 50% and 80% of the total electricity used. Very rarely have I come across pumps operating with fully open discharge valves. The same is the case for fans with dampers. ...

  • Large Diameter Impellers Make Trash Pumps More Versatile

    The introduction of these impellers allow for a higher range of discharge pressure. Pumps are available in many types—diaphragm, positive displacement and progressive cavity—but the most common is a centrifugal pump. Centrifugal pumps have an impeller that spins, transferring energy to the fluid by centrifugal force and directing the water to the discharge point within the ...

  • How a wet dust collector can prevent a violent explosion (and more!)

    Explosive dust is a major concern among metal finishing operations, and recent changes in the National Fire Protection Association regulations have made compliance more difficult. Metalwork grinding and sanding produces a fine metallic dust that, even after being filtered from the air, can smolder, catch fire, or even explode violently if it’s exposed to a spark. Aluminum, lithim, ...

  • Controoling chlorine costs

    The most widespread disinfectant used in the treatment of drinking water is chlorine, which can be applied in a variety of ways. History has taught us that, in bacteriological terms, chlorinating water is a proven way of disinfecting drinking water. After all, more than 75 years have passed since chlorine was used to disinfect drinking water for the first time. Many years of experience have shown ...


  • Wastewater Treatment in Turbo Mode

    Sulzer turbocompressors type ABS HST are successful in wastewater treatment. Today, 2000 units are installed around the world—for example, in municipal plants like in the city of Sögel, Germany. Here, the turbocompressors not only reduced the operating costs but also helped the plant to cope with load fluctuations. The secret behind this success is an advanced design with proven ...
