Factors influencing colloidal particle transport in porous media

he mobilization/immobilization of colloidal sized particles which have high surface areas per unit mass is an important process occurring in groundwater flow systems. The general objective of this work was to elucidate physical and chemical factors affecting colloidal particle (Brownian and non-Brownian) transport in porous media. The mechanisms of colloidal particle transport/deposition in porous media (deep bed filtration) were experimentally tested under the conditions of a simple solution chemistry and typical groundwater flow velocity (0.9 and 2.7 m/day).;The model experimental system involved using latex suspensions (0.1, 1.0, and 10 ;Brownian diffusion was significant for 0.1 ;The ability of the one dimensional advective-dispersive equation to model the particle transport in porous media was examined by comparing the predicted to experimental results.
