Abstract
Granular filters retain base material within the narrowest constrictions of their void network. A direct
comparison of the base material particle size distribution (PSD) and the filter constriction size distribution
(CSD) cannot easily be used to assess fi
lter
-
base compatibility. Here a conceptually simple random
-
walk
network model using a filter CSD derived from discrete element modelling and base PSD is used to assess filter
-
base compatibility. Following verification using experimental data the model is a
pplied to assess empirical
ratios between filter and base characteristic diameters. The effects of filter density, void connectivity and
blocking in the first few filter layers are highlighted.
