Specifications include, but are not limited to: The District desires to pre-qualify incinerator system supplier(s) (ISS) for the construction of a fluidized bed incineration (FBI) system as part of a Design-Build team through a Fixed-Price Design-Build contract at two (2) of its treatment facilities: the Bissell Point Wastewater Treatment Facility (WWTF); and, the Lemay WWTF. The new FBI systems will include the incinerator reactors, heat exchangers, blowers, emissions control equipment, ash handling equipment, ductwork, controls, and associated items. Preliminary FBI capacities (firm) are as follows: Bissell Point 240 dry tons per day (dtpd) with four units nominally sized for 80 dtpd each. Lemay 160 dtpd, with three units nominally sized for 80 dtpd each. New sludge dewatering processes will also be provided at both WWTFs as part of the design- build contract. Centrifuges will be used to dewater a combined blend of primary sludge, WAS, and scum flow prior to incineration. Sludge cake conveyance from the dewatering centrifuges will be by hydraulically driven piston pumps and will include screw conveyors as needed.
