Wastewater Case Studies and Whitepapers

  1. Increasing Capacity: AE-DENITRO + Hydrotech Discfilter

    The City of Palm Coast, located on the east coast of Florida, expanded their existing Wastewater Treatment Plant (WWTP) to increase capacity to 6.83 MGD due to population growth, as well as add the production of reclaimed reuse water for use within the City.

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 While an outdated oil heating system contributed to the overall inefficiency, the plant’s 30-year-old multistage centrifugal aeration blowers accounted for as much as 80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

  3. Reducing Odor & Corrosion

    Veolia faced the daunting challenge of managing two large WWTP’s as well as finding a better and more cost effective solution for odor and corrosion control.

  4. MBBR Helps Reduce BOD Loading In Paper Plant Effluent

    Inland Empire Paper Company (IEP), located in Millwood, WA specializes in the production of newsprint paper using a combination of mechanical pulp and recycled newspaper pulp. IEP produces an average of 525 tons per day of newsprint and specialty paper products in 20 to 40 pound weight paper. 

  5. Repair Of Major Damage To High Density Polyethylene Wastewater Pipeline

    Leprino Foods, the world's largest mozzarella cheese producer, operates two plants that share one wastewater pipeline – a 16” SDR11 High Density Polyethylene Pipeline (operating at approximately 160 PSI). During dirt work an “auger” hit the wastewater pipeline and drilled an 8” diameter hole in the line. Leprino needed immediate access to a repair fitting for this line.

  6. What Does It Take To Really Impress Your Customer?

    Service. A large part of customer service is creating a seamless experience between the customer’s expectation, and your ability to exceed their anticipated need.

  7. Mobile Membrane Systems Provide Emergency Response

    When emergencies inevitably arise, municipal operators need to be prepared to respond immediately to restore services in order to provide safe, reliable water to their customers. Take for example the City of Cisco, Texas.

  8. The Benefits Of Reusing Wastewater

    Since water is an essential element in food or beverage operations, reusing it can reduce a business’s water usage ratios, help meet sustainability goals, lower supply risk and contribute to cost savings, making it a top priority for many companies today.

  9. White Paper: Stormwater Retention For A Modular Green Roof Using Energy Balance Data
    New York City stormwater is a major cause of water pollution in the harbor and estuaries. This is due to the vast areas of impervious surfaces (e.g., rooftops, pavements, sidewalks) that rapidly shunt runoff into the combined sewage overflow (CSO) system.
  10. Ozone Gas Flow Monitoring For Water Treatment Systems

    Many municipal water treatment plants utilize Ozone Treatment Systems to produce clean water for residential and industrial users. While all the various types of water treatment systems have their advantages and disadvantages, Ozone (O3) systems provide excellent disinfection and avoid some of the chemical byproduct problems experienced with the use of chlorination.
