  1. 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.

  2. CAGI Data Sheets: Blower Performance Comparison Technical White Paper 2/13/2018

    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.

  3. Why ASME PTC10 Is Not Sufficient To Define Testing Of A High Speed Turbo Blower 1/22/2016

    The technology to produce low pressure air, an energy intensive ingredient in the wastewater process, has made significant steps forward in recent years. Unfortunately, the specifications for testing these new sophisticated air producers have not kept pace.

  4. Switch To Hybrid Blowers Offsets 68% Electrical Rate Increase For WWTP 3/2/2016

    The Old Orchard Beach Wastewater Treatment Plant (WWTP) serves the town of Old Orchard Beach, Maine, a coastal resort community where the population swells from 9,000 year-round residents to 75,000 in late June through early August, when seasonal residents and day trippers descend for the peak summer months.

  5. HST Turbocompressor Survives Category 4 Hurricane 4/1/2020

    Victoria, Texas, is a small South Texas town of approx. 65’000 people just 30 miles inland from the Gulf of Mexico. This area is considered as humid subtropical, and the temperatures regularly exceed 100°F for the months of June through August. A record high temperature of 111°F was recorded in September 2000 and a record low of 9°F in December 1989. This location displays one of the most extreme temperature differentials in the United States. The HST high-speed blower was used in the new plant design which replaced an older two-stage trickling filter design in the Victoria WWTP.

  6. Applying Variable Speed Compressors In Multiple Compressor Applications 8/23/2021

    Variable speed control for all types of industrial equipment is readily available on the market with competitive pricing to non-variable speed controlled alternatives, including in the air compressor industry. With the advent of prescriptive rebate programs for variable speed compressors and other equipment, the demand for these types of controls has increased.

  7. Wastewater Treatment Plant Reduces Energy Consumption, Noise With Turbo Blower Technology 6/24/2013

    Built in 1974, the Blue River Wastewater Treatment Plant in Silverthorne, Colorado, provides wastewater services to the communities of Silverthorne, Dillon, Dillon Valley, Buffalo Mountain, and Mesa Cortina. Faced with rising energy costs and aging equipment, the Silverthorne-Dillon Joint Sewer Authority (JSA) identified a need to replace the plant’s original multistage centrifugal blowers with new technology that would reduce energy consumption and provide steady and reliable operation.

  8. Complete Blower Package Results In Quiet Operation, Easy Maintenance 9/21/2016

    Until 2012, the Kaufman, TX, Wastewater Treatment Plant (WWTP) operated two separate aeration basins with mechanical surface aerators. As the plant’s equipment aged and required more frequent and expensive repairs and maintenance, the City of Kaufman followed its engineering firm’s recommendation to install a new, more efficient, fine bubble-diffused air system rather than simply replacing its old mixers with in-kind equipment.

  9. 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.

  10. Repair Or Rethink 8/7/2015

    The Moundsville Wastewater Treatment Plant in West Virginia chooses not to fix a broken blower unit, but rather to correct an outdated approach. The result is a savings of $50-60K a year in energy costs.
