Dewatering of water and wastewater treatment sludges was examined through mathematical modeling and experimental work. The various components of the research include: (1) chemical analyses of water treatment sludges, (2) drainage and drying studies of sludges, (3) a mathematical model to describe sludge drainage and drying on sand beds, and (4) a procedure to optimize the size of sand beds. Computer simulation studies were conducted of wastewater and water treatment sludges. The output of this 20-year simulation under six weather conditions was a random variable, the required dewatering time, and its associated frequency distribution. Of the parameters describing sludge characteristics, solids content had the most important effect on dewatering time. Economic analyses were applied to the outputs of simulation for finding an optimum system design.
