5. Sedimentation
When the uid ow is directed downward through a lter, gravita-
tional sedimentation effects will cause particles to settle vertically
through the ow streamlines, as the latter distort around the
collector (Figure 5.5).
6. Interception
If the suspended particle radius is greater than the distance between
the ow streamline that contains the particle and the collecting
media grain, then the suspended particle will contact the target, in
the absence of any repulsive mechanisms (Figure 5.6).
