Wastewater Treatment Case Studies and White Papers

  1. ACTIFLO And Hydrotech Discfilter: A Two Stage Process
    10/18/2016

    The state of Minnesota instituted a new water quality requirement that limits cities along the Minnesota River to a 1 mg/L Total Phosphorus limit by 2015 to prevent algae blooms and resulting pollution problems.

  2. City Of Tacoma, WA, Continues To Choose PolyBlend® Dry Polymer Preparation Systems After 25 Years Of Reliable, Consistent Performance
    8/10/2016

    Serving over 200,000 ratepayers, the City of Tacoma operates two award-winning wastewater treatment plants.

  3. Field Test Turns Clamp-On Ultrasonic Skeptics Into Believers
    12/11/2018

    After having been reluctant of using clamp-on ultrasonic flow meters for energy measurement in cogeneration plants in large residential and commercial buildings, a U.S.-based engineering firm was convinced by the clamp-on meter’s strengths.

  4. Choosing The Right Water Disinfection
    7/15/2019

    In the mid-to-late 1800s, chlorine had been used sporadically to help control infection in hospitals and drinking water. Common water treatment did not start in the U.S. until the early twentieth century when increasing cases of waterborne illnesses prompted many large cities to begin large scale filtration of water supplies.

  5. JWC’s Honey Monster Helps Big Fish Environmental Find Clean Water
    8/2/2010

    For several years, local Michigan municipalities were overloaded with septage disposal issues and it was difficult for private pumpers to offload as land-application of septage became illegal. So John Campbell, founder of Big Fish Environmental and a 29-year veteran of septic tank pumping, started developing a unique and efficient septage receiving and treatment plant design.

  6. City Saves Big Money By Using Cloth Media Filters To Treat CSO Discharge
    4/12/2019

    The City of Rushville, Indiana had to remedy a consent order filed in 2007 for its untreated combined sewer overflow (CSO) discharges that were polluting the Flatrock River, a violation of the Clean Water Act. The city originally planned to install a 1 MGD stormwater storage tank, but was approached by Aqua-Aerobic representatives with a pilot test proposal utilizing a new technology.

  7. West Virginia City Says It All Adds Up With The FPI Mag Flow Meter
    10/29/2015

    The city staff of Buckhannon, West Virginia, recently ran into a situation that didn’t add up. A flow meter at one of the city’s booster stations was indicating a flow rate higher than the capacity of the station’s pumps. The staff contacted the applications team at McCrometer about its flow meter accuracy problem.

  8. City Saves Money And Energy With Real-Time Control System
    12/12/2013

    Because blowers are run continuously, energy costs associated with the aeration basin are typically the largest expense for wastewater facilities. The wastewater treatment plant in the city of Grand Rapids was looking to reduce aeration energy costs and recently upgraded the facility with a Hach Real-Time Control System. The result was a nearly $60,000 energy efficiency incentive payment from Consumers Energy, and the plant is now on track to save the city more than 735,000 kilowatt hours of electricity and $62,000 annually.

  9. Small-Town Mayor Tackles A Big Problem
    7/26/2017

    Public concern was mounting over the lack of adequate wastewater treatment for the vast majority of homes in Fulton, Alabama. High groundwater levels contributed to septic system failures at some residences, while many others had no septic system at all.

  10. SEPAREL Available In External Perfusion And Internal Perfusion Varieties
    2/6/2017

    SEPAREL hollow fiber membrane modules from the DIC Corporation provide exceptional degasification performance with a proprietary non-porous membrane which utilizes a Surface Skin membrane (SS membrane) for enhanced degasification. Available in both internal perfusion (PF series) and external perfusion (EF Series) varieties, SEPAREL modules are optimized for a variety of degassing applications.
