Wastewater Blowers Articles

1. 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Wastewater Treatment Plant in West Virginia chooses not to fix a broken blower unit, but rather to correct an outdated approach.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.

2. Freeport Wastewater Treatment Plant Saves Money And Energy With Hybrid Blowers 9/30/2013

   Best known as the home of outdoor retailer L.L. Bean, the community of Freeport is a popular summer destination on the shore of Casco Bay in southern coastal Maine. In 2010, the Freeport Sewer District brought in engineering firm Woodard & Curran (also of Freeport), to conduct an energy analysis of the Freeport Wastewater Treatment Facility. The assessment revealed that the Freeport plant consumed more than 8.9 kBtu per gallon of wastewater treated, more than double the national average of 4.1 kBtu per gallon. While an outdated oil heating system contributed to the overall inefficiency, the plant’s 30-year-old multistage centrifugal aeration blowers accounted for as much as 80 percent of the electricity consumption.

3. 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.

4. Air Diffusion Systems Helps Francesville With New Aeration System 2/15/2019

   In 2012, the Town of Francesville in Indiana contacted Air Diffusion Systems to provide a solution for several suspended solids violations and energy efficient treatment. Air Diffusion Systems was able to provide an unique solution to correct biochemical oxygen demand (BOD) and total suspended solids (TSS) problems using Kaeser Compressors’ CB Com-paK blowers.

5. 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.

6. Turbo Blower Technology Saves Money And Energy For City Of Adelanto WWTP 10/27/2014

   The City of Adelanto, Calif., wastewater treatment plant (WWTP) receives an average flow of 2.2 million gallons per day (MGD), but had a permit that allowed treatment of only 1.5 MGD.

7. Comprehensive Compressed Air Assessments: The 5-Step Process 10/10/2024

   The objective of this paper is to define the five steps required in a compressed air assessment. We will use a real-world example with system information from a magnetic materials manufacturer to clearly illustrate each step.

8. After 30 Attempts To Cut Through The FOG, The Wet Well Wizard Makes Major Improvements 8/31/2020

   It took 30 attempts, but the Wet Well Wizard was finally able to cut through the FOG at the Memorial Park Pump Station (MPPS).

9. 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.

10. Leveraging Rentals For Pneumatic Conveying Applications 5/18/2020

    Pneumatic conveying applications are critical to many facilities – when you can’t move material you can’t make or sell your product. Because of a historical lack of availability of specialized rental blowers and compressors for pneumatic conveying, plants often ether accepted the production outage or rented a more readily available 2 stage oil-free rotary screw compressor designed for 90-150 PSIG plant air service that is very inefficient at the reduced pressures needed for pneumatic conveying.
