Wastewater Case Studies and Whitepapers

  1. Milk Waste - BOD, FOG, PO4

    A milk producer operates an evaporated milk production facility that generates an average of 58,000 gpd of contaminated water with spikes of 1,200 gallons up to 12 times per day. Two 2,000 gallon batch tanks are used for pH adjustment before discharge. Most of the flow goes through the tanks.

  2. Screenfield Retrofit Saves Greenwood Lakes WRF Time And Money

    Greenwood Lakes Water Reclamation Facility, located in Seminole County, Florida- just north of Orlando, treats approximately 694 million gallons of wastewater each year.

  3. Mexican Power Plant Meeting Tough Wastewater Challenges
    Recovering water for boiler feed makeup can come with many challenges for power stations; however, the level of complexity involved with treatment is raised considerably when having to deal with municipal wastewater.

  4. The Good And Bad Of Wastewater Instrumentation: Pros, Cons, And Opportunities

    Instrumentation is heavily pushed to achieve efficiency, but it only works when you use it correctly – and many utilities don’t.

  5. Essential Answers To Important pH Questions – Part 2

    pH measurement plays an important role in virtually every industrial process and an equally essential part in environmental regulatory compliance. Many of the below questions pop up every day whether in chemical processing plants, power plants, water and wastewater plants or biopharmaceutical processing.

  6. Ultrasonic Vs. Radar Level Technology In The Water Industry

    In recent years, the debate about which technology is best suited for water and wastewater level measurement and monitoring is heating up. There are those who argue that ultrasonic level technology has been uncontested as the standard for level and open-channel measurement applications in the water industry.

  7. Ozone Plays Critical Disinfection Role At Water Reclamation Plant

    The Rio Grande River and the two major aquifers in the El Paso, TX, area had been dried up for decades when El Paso Water Utilities (EPWU) developed the Fred Hervey Water Reclamation Plant, the nation’s first full-scale wastewater reclamation plant to use tertiary treatment to restore wastewater to national and state potable water standards.

  8. Fine Screen Retrofit Cuts Upgrade Costs By $1M

    To preserve Hawaii’s natural beauty, keep up with growth and ensure regulatory compliance, the US Army Schofield Barracks, Hawaii’s largest Army post, recently upgraded their wastewater treatment facility located on the island of Oahu. The result was improved efficiency and water quality, and decreased environmental impact on the region. By JWC Environmental

  9. Power Plant Uses 3M Liqui-Cel Membrane Contactors To Remove CO2 From Water

    A major power plant in Thailand is using 3M™ Liqui-Cel™ Membrane Contactors to remove carbon dioxide from a DI water system. The system is an expansion project and will be used to feed a high pressure boiler. Liqui-Cel membrane contactors are being used to lower the CO₂ inlet into an Ionpure Electrodeionization (EDI) system. Carbon dioxide adds an ionic load to the EDI system, which can reduce the performance of the system. Manufactures of the EDI equipment suggest lowering the inlet CO₂ to reduce the load on the equipment and improve the water quality.

  10. Article: Aerators Enhance Aerobic Digestion Process
    The city of Eden, N.C., operates an extended aeration process designed for an average flow rate of 13.5 mgd with a mixed liquor suspended solids concentration that typically checks in about 6,000 mg/l
