Modeling colloid attachment, straining, and exclusion in saturated porous media.
A conceptual model for colloid transport is developed that accounts for colloid attachment straining, and exclusion. Colloid attachment and detachment is modeled using first-order rate expressions, whereas straining is described using an irreversible first-order straining term that is depth dependent. Exclusion is modeled by adjusting transport parameters for colloid-accessible pore space. Fitt...
متن کاملCoupling of physical and chemical mechanisms of colloid straining in saturated porous media.
Filtration theory does not include the potential influence of pore structure on colloid removal by straining. Conversely, previous research on straining has not considered the possible influence of chemical interactions. Experimental and theoretical studies were therefore undertaken to explore the coupling of physical and chemical mechanisms of colloid straining under unfavorable attachment con...
متن کاملQuantifying colloid retention in partially saturated porous media
[1] The transport of colloid-contaminant complexes and colloid-sized pathogens through soil to groundwater is of concern. Visualization and quantification of pore-scale colloid behavior will enable better description and simulation of retention mechanisms at individual surfaces, in contrast to breakthrough curves which only provide an integrated signal. We tested two procedures for quantifying ...

متن کاملColloid mobilization in water-saturated porous media under transient chemical conditions.
This research focuses on the effects of transients in porewater chemistry on colloid mobilization within water-saturated porous media. We develop a model that couples equations for solute transport with those for colloid release and transport. The model accounts for heterogeneity in the interaction energies between deposited colloids and the mineral grains by dividing the immobile-phase colloid...
