Colloid Facilitated Transport in Natural Porous Media: Fundamental Phenomena and Modelling

2007
Reactive transport phenomena, in particular, the transport of contaminants, are of fundamental interest in environmental sciences. The presence of hazardous chemicals in the subsurface environment has become an important driving force to develop reactive transport models capable to predict their fate (Dagan 1989; Jury and Roth 1990; Sardin et al. 1991;

Models of Sorption Type for Colloid-Facilitated Transport in Aquifers

2011
This chapter considers sorption-based numerical models simulating 1D migration of chemical species in the presence of mobile reactive colloids. One of the model extensions includes a module for simulating the migration of a colloid mixture characterized by heterogeneous distributions of particle size and sorption properties.

A Thermodynamics-Based Conceptual Model for Colloid-Facilitated Solute Transport

2011
As mentioned above (Sect. 19.1.2), changes in the physicochemical conditions in the system over space and time, which take place in unsteady-state migration flows, reduce the potential of the above-considered sorption isotherm-based models with time-invariant coefficients, in particular, models describing colloid-facilitated transport.

Theoretical Analysis of Colloid-facilitated Transport of Radionuclides by Groundwater

2011
Mechanisms of colloid-facilitated transport of radionuclides by groundwater are considered for three types of radioactive colloids: intrinsic colloids, primary colloids and pseudocolloids. Effect of elevated velocity of colloid facilitated migration is analyzed.
