• CAGI Data Sheets: Blower Performance Comparison Technical White Paper

  Comparing blower performances across different manufacturers and technologies has long been a difficult task. For many years, it was all too easy to present data that, although accurate, was potentially misleading. Manufacturers were selective about what information they published as well as what conditions they chose to specify performance. The result was a numbers game the buyer frequently lost. Fortunately, the Compressed Air and Gas Institute (CAGI), in cooperation with its members, has developed a tool for a fair comparison between blowers.

• The Proper Application Of Rotary Lobe And Rotary Screw Blower Technology

  9/28/2017

  Written by Kaeser’s system experts, this white paper compares rotary lobe and screw blowers, isochoric and isentropic compression, and how to properly apply these technologies for designing an energy efficient system.

• Upgrade To Diffused Aeration Results In Significant Energy Savings

  12/12/2013

  After 35 years of use,  the fiberglass jet aeration manifolds in the Western Regional Water Reclamation Plant (Dayton, Ohio) had deteriorated, rendering four of eight wastewater aeration tanks inoperable. Managers recognized an opportunity to utilize a fine bubble diffused aeration system that eliminated the need for the pumps. The result: higher oxygen-transfer efficiency and reduced power costs to operate the system.

• Los Alamos WWTP Gains Turndown Capability And Saves Energy With Hybrid Blowers

  Los Alamos, NM, the former site of topsecret laboratories where government scientists developed the atomic bomb during World War II, is once again a town at the forefront of new technology.

• Self-Tuning System Provides Big Leap In DO Control

  5/4/2021

  The City of Cumberland (MD) wastewater treatment plant could see wild swings in its dissolved oxygen (DO) levels until it replaced its air control system with Aerzen AERprocess, an intelligent airflow control system. Now, the city enjoys vastly improved DO control in individual zones and across the entire process, as well as significant savings on its energy bills.
