The general objective of the research program was to investigate the factors affecting the thickening of various types of liquid-solids suspensions by gravity sedimentation of interest in sewage treatment. The more specific aims of the program were as follows: to study the fundamental concepts and mechanisms involved in the gravity thickening process on both a batch and continuous flow basis; to determine the significant loading parameters which affect the performance of the continuous flow thickening process and attempt to numerically evaluate the relationship between loading and performance of the process as applied to various solids suspensions and sludges; to determine if the results of batch thickening tests on a particular solids suspension can be used to predict the limiting load and design capacity of a plant scale continuous flow thickener; and to develop a rational method for the design and operation of full scale thickeners.
