MSD Bissell & Lemay Fluidized Bed Incinerator

A transformative upgrade is planned for both the MSD Bissell and Lemay Plants, involving the replacement of existing multiple hearth incinerators with state-of-the-art fluidized bed incineration systems. This new process will significantly improve efficiency, environmental performance, and reliability.

The fluidized bed incineration system will feature advanced components including fluidized bed reactors, sand handling systems, fluidizing and purge air blowers, primary and conditioning heat exchangers, wet scrubbers, granular activated carbon (GAC) systems, wet electrostatic precipitators (WESP), and induced draft (ID) fans, along with all supporting infrastructure.

To prepare sludge for incineration, a new sludge dewatering system will be installed. Key elements of this system include sludge receiving wells, raw sludge pumping, high-efficiency centrifuges with polymer feed systems, sludge cake receiving bins, conveyors and pumps for sludge conveyance, a centralized sludge cake receiving station, and a truck loading facility.

A newly constructed Solids Processing Building will house the incineration and dewatering equipment. Additional scope includes the demolition of the existing Solids Handling Building and associated stack, extensive sitework and exterior improvements, and installation of updated electrical and control systems.

This comprehensive project represents a significant step forward in sustainable wastewater treatment and solids management for the Metropolitan St. Louis Sewer District.
