Abstract

The objectives of this work were to include chemical effects in the fundamental theories that describe the deposition of particles in granular media filters, to test the theories experimentally, and to use these results in assessing requirements for effective filtration and the capabilities of the process. In particular, the effects of changes in solution chemistry on the deposition of relatively large or non-Brownian particles are examined. Such particles are large enough, typically with diameters greater than 2-3 /um, that their transport is not significantly affected by Brownian diffusion.
