PROJECT HIGHLIGHTS

Commissioned April, 2006 Industrial WW, CAS Retrofit Permit(s); Reuse+Discharge 10/NA/NA     (TN/TP/Turbidity) Poultry Processing ⇒ River MMF Capacity: 0.9 MGD $4.67/gal 0.5 FTE (Full‐Time Employees)
Waste solids are handled through aerobic digestion followed by a belt press.

DESCRIPTION

The Moroni Wastewater Treatment Plant (WWTP) provides treatment to the City of Moroni and the Moroni Feed Company (a turkey processing facility). This combination of residential and industrial waste proved to be difficult to treat with the existing treatment system and caused discharge permit excursions. Ovivo MBR technology was selected to bring the plant back into compliance. The existing headworks facility was upgraded with new fine screens to improve the screenings operation. The existing dissolved air flotation unit, which was offline, was converted into a primary clarifier to assist in removing solids from the waste stream.
