Chronic blockages were attributed to pump design, byproduct grease from restaurants, and medical waste from assisted living and nursing homes along the lines.

  2. North Carolina Treatment Plant Eliminates Taste And Odor Issues With Ozonation
    3/9/2015

    Enactment of the Long Term 2 Enhanced Surface Water Treatment Rule and the Stage 2 Disinfectant-Disinfection Byproduct Rule (D/DBPR) will require both large and small drinking water utilities to reduce total organic carbon (TOC), Cryptosporidium, and disinfection byproducts (DBPs) in the treated drinking water distributed to the public.

  3. Wastewater Treatment System Achieves Stringent Water Quality Discharge Limits And Reduces Costs

    To ensure treated water complied with the most stringent drinking water standards, including the Environmental Protection Agency (EPA) Stage 2 Disinfectants and Disinfection Byproducts Rule (State 2 DBPR), the City of Cambridge, MA, WTP decided to implement a robust multibarrier treatment solution.

  5. Mixers Prevent Buildup And Reduce Wetwell Cleaning Charges
    3/9/2015

    The City of Reno, NV, has long battled the buildup of fats, oils, and grease in the wetwells of wastewater lift stations in the valleys within this high desert city. Recently, the city set out to address the problem and reduce the associated costs.

  6. Mixers Clear FOG And Reduce Operating Costs By More Than 80%
    3/8/2015

    The Cypress Creek WWTP in Florence, AL, uses an extended aeration activated sludge process with a design capacity of 20 million gallons per day (MGD). Cypress Creek serves mostly residential customers, but about 15 percent of its influent comes from industrial sources, and their discharge to the plant contains large amounts of fats, oils, and grease (FOG).

  7. Flygt Mixers Clear Sediment And Save Man-Hours For San Antonio Utility
    3/5/2015

    For almost 50 years, CPS Energy of San Antonio has drawn water from the San Antonio River to recharge two man-made lakes that provide cooling water for their power plants.

  8. Solving Foaming Problems At Your WWTP
    3/1/2015

    This project provides an unusual "before-and-after" comparison of how a high-solids loaded digester system with a Rotamix mixing system performed before and after the Foambuster was installed.

  9. Improving Influent Screen Washing For A Fraction Of The Estimated Cost
    3/1/2015

    The use of Vaughan's self-priming chopper pump and nozzles upstream of the influent screens is increasing the amount of fecal matter passing through the influent screens, which in turn improves plant efficiency and greatly increases the amount of cogenerated electricity from digester gas.

  10. Pump Station Bar Screen Solves City’s Unique Problem
    2/24/2015

    As representatives of a small community, the Mendocino City Community Services District administrators felt strongly that they needed to deliver terrific wastewater treatment value at the lowest cost for their taxpayers.
