The solids processing and incineration-energy recovery system at the Metropolitan Waste Control Commission (MWCC) wastewater treatment plant in St. Paul, Minn., is unique in the wastewater treatment field. The system consists of innovative processes including two types of solids dewatering devices-twin-roll filter presses and plate-and-frame diaphragm filter presses, and two new and four rehabilitated multiple-hearth incinerators. Four of the incinerators are equipped with energy recovery boilers, an economizer, heat wheels, and rotary solids dryers. The plant scum and the odorous gases generated from the thermal solids conditioning process are destroyed by combustion in the incinerators.
