This two volume set presents in detail technical design information for the following sludge treatment and disposal processes: incineration, pyrolysis, composting, land utilization, and landfilling. The discussion of each process includes, where possible, a presentation of performance data for existing operations as well as operation and maintenance experiences and energy and cost information. Each chapter includes one or more design examples to illustrate step-by-step, the philosophy, rationale, and methodology behind the design of the particular process. The goal of processing and treatment research and development is to produce technology alternatives which can be used to prepare the sludge for application to the land or for one of the conversion processes so that the total cost of handling or disposal is minimized.
