Aeration & Blowers White Papers And Case Studies

  1. Eliminating Sludge Islands In Your Wastewater Lagoon
    12/12/2013

    Old municipal and industrial wastewater lagoons have the tendency to build islands of sludge at various locations around the lagoon. It is most common for older lagoons to build such islands wherever wastewater enters the lagoons. By Jim Dartez

  2. 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.

  3. Sewer Authority Ends Plant Bypasses And Introduces Nutrient Removal With New Treatment Process
    11/14/2013

    The original contact stabilization activated sludge process at the Portage Area Sewer Authority generated hydraulic limitations that required repeated bypasses during heavy rainfall. Find out how the treatment plant upgraded its secondary treatment aeration system to include nutrient removal through a nitrification/denitrification/phosphorus process and has successfully processed I&I induced surges that reached a 10-MGD peak.

  4. Brewery Reuses Water For Factory Wash-Down
    11/11/2013

    Looking to reduce its water footprint, Shepherd Neame Brewery invested in a complete membrane bioreactor (MBR) wastewater recovery and re-use plant. Learn how the new plant's aeration system has helped to reduce the brewery's water-to-beer ratio to an industry-leading value of 3:1.

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 While an outdated oil heating system contributed to the overall inefficiency, the plant’s 30-year-old multistage centrifugal aeration blowers accounted for as much as 80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

  6. Auburn University Aerator Test Results
    9/18/2013

    The DO2E Aerator differs from its competitors in several key areas. Our system is equipped with a patented mixing chamber and air manifold system that no other system has.

  7. Advanced Oxidation Processes: A.O.P. Whitepaper
    9/10/2013

    Advanced Oxidation Processing is the generation and implementation of hydroxyl radicals (HO+) to oxidize contaminates in air and water. It is considered one of the most powerful oxidants readily available and it produces NO harmful by-products.

  8. Champion Paper Case Study
    9/1/2013

    In August 2004, tests were conducted on 2 Primary Aerated stabilization basins with approximately 2,200 horse power (hp) of aeration capacity.

  9. Plant's Aeration Output Increased While Electricity Is Decreased
    8/14/2013

    Located in New Haven County, Connecticut, in the eastern USA, the wastewater treatment plant in Meriden has a design inlet flow of 43,911 m3/day (11.6 mgd) with a maximum inlet flow of 143,386 m3/day (38.0 mgd). Upgraded in the 1960s and 1980s, the plant has been in existence since the 1800s.

  10. 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.
