OSTI ID:6419193

This project has been aimed at further development of the theory of separation of solids from liquids in operations involving compressible particulate beds or sediments as found in filtration, centrifugation, and sedimentation. Generation of reliable data under well-defined conditions and integrating the areas of pre-treatment, thickening, and separation are objectives of the research. Particle characteristics are being related to suspension behavior and cake structure. Sedimentation rates and cake structure are being correlated. The initial structure of deposits as affected by surface charge, suspension concentration, and agitation is being studied in relation to resistance to flow. Included in the program are internal flow mechanisms involving porosity and pressure distribution. Fine particle migration is being related to cake and medium blinding. An attempt is being made to relate the microscopic particle characteristics to the macroscopic behavior of cakes and sediments.
