the particles to the effluent more effectively. However, as the flow paths
are plugged, the pressure difference across the porous media may exceed
the critical stress necessary to break some of the plugs. Therefore, these
plugs break and release particles into the flowing media increasing its
particle concentration. Subsequently, the deposition process progresses to
form new plugs during which the flowing media particle concentration
