  6. 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.

  7. 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.
