    Reactivated sludge was recycled back into the wastewater

    treatment facility, providing healthier activated sludge to the

    treatment tanks for future treatment needs.

    After one month of operation all complaints of foul odors

    were resolved.

    Higher concentrations of healthy activated sludge in the

    activated treatment tank resulted in better discharge effluent

    quality and lowered operation costs.

    Plant has been active since March 2016.
