Colloid Transport in Porous Media: A Continuing Survey of Conceptual Model Development

Abstract : The grand challenge problem of understanding colloid transport and filtration processes in porous media continues to defy fundamental solution, limiting progress of engineering science in in fields ranging from human health to water quality to materials engineering to energy production to microbiology. Focused experimental and modeling studies continue to chip away at our ignorance, in particular as regards colloid interactions with surfaces and colloid motion. In this continuing survey we give an updated overview of some of the currently active research areas with a focus on the exciting new conceptual model development and testing, with reference to pore-to-continuum scale experiments and simulations.
