• Freeport Wastewater Treatment Plant Saves Money And Energy With Hybrid Blowers

  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 While an outdated oil heating system contributed to the overall inefficiency, the plant’s 30-year-old multistage centrifugal aeration blowers accounted for as much as 80 percent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.

• 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.

• 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.

• 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.

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Wastewater Treatment Plant in West Virginia chooses not to fix a broken blower unit, but rather to correct an outdated approach.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