Abstract:

The dynamic analysis of behavior of solid particles in porous media such as settling processes are important for the dimensioning increasingly precise of pieces of equipment that promote the solid-liquid separation. Several factors can influence in dynamics of the fall of solid particles into a fluid medium; among them, the shape, distribution of sizes, and particle density. The main objective of this work is to analyze the behavior of solid-solid system based on the shape, size distribution and density of solid particles. The initial settling velocity in batch settling tests and the accommodation of particles in the sediment formed are evaluated for different materials. The gamma-ray attenuation technique was used in the experimental tests. Comparison of results obtained allowed evaluating in an exploratory research the significance of variables involved.
