A capital improvements program is underway at the Lynn Regional Wastewater Treatment Facility located in Lynn, Massachusetts, to upgrade aging preliminary treatment and biosolids handling facilities. As part of this program, new dewatering and fluidized bed incinerator (FBI) systems are replacing the existing systems for incineration of dewatered primary and secondary treatment biosolids with ultimate disposal at an onsite ash landfill.

This program is being administered under a design/build/operate project delivery format. The design and construction period for the capital improvements program is 34 months and the operating term is 20-years. The project began in the fall of 2001 with new dewatering systems scheduled to be operational in mid 2003, and incinerator and ash handling systems scheduled to be operational in mid 2004.

This paper focuses on the residuals and biosolids management facility improvements, beginning with a brief background on the Lynn Regional Wastewater Treatment Facility, followed by a description of the design criteria for the new dewatering and FBI systems, a discussion of the project challenges associated with design, construction, and regulatory approval, and a summary of the major FBI system components.
