Understanding transport of colloids (microorganisms, clays, nanoparticles, etc.) during (transient) flow in (variably) saturated porous media is very important in a number of applications. Important examples are drinking water production (well clogging, deep bed filtration, groundwater recharge, removal viruses by passing water through soil), oil production (formation damage), design and management and remediation projects. Some colloids are considered as contaminants (such as viruses, bacteria, some nanoparticles); some others act as carriers of contaminants that may adsorb onto and migrate with colloids (this is known as colloid-facilitated transport).
In this short course, we discuss processes that affect the fate of colloids at various scale (molecular, grain/pore, and REV scales). In particular, surface-surface interactions, colloid filtration theory, removal mechanisms and all factors that affect attachment/detachment will be discussed. We will also present principles of virus transport in soil. Special attention will be given to the transport in unsaturated soil and two-phase flow under transient flow conditions. Results of a large number of laboratory and field experiments under both saturated and unsaturated conditions, for the study of movement of viruses and colloids through soil will be presented.
Knowledge of groundwater flow and (nonreactive) solute transport is required.

- Short overview of flow and solute transport in soil and groundwater – 1 hour
- Removal of viruses from water by means of soil passage; Field studies in The Netherlands – 1 hour
- Laboratory studies of virus transport; batch experiments; column experiments – 2 hours
- Effect of water properties (pH, ionic strength, and temperature) on virus removal – 1 hour
- Study of virus and colloid transport under unsaturated conditions;the effect of water saturation; Theory and experiments – 2 hours
- Study of virus and colloid transport under unsaturated conditions and two-phase flow; the effect of transient conditions (change of saturation and/or composition) – 3 hours
- Co-transport of contaminants by colloids under saturated/unsaturated conditions – 2 hours
The short course is given by Majid Hassanizadeh (Utrecht University, The Netherlands / University of Stuttgart).
Prof. Hassanizadeh is an Emeritus Professor of Hydrogeology at the Faculty of Geosciences of Utrecht University and SFB 1313 senior professor and external partner of the University of Stuttgart. His recent appointments have been: Professor at the Faculty of Civil Engineering and Geosciences, Delft University of Technology (2001-2003), and Professor at Utrecht University (2004-2018).
