In most fihrations it is highly probable that more than one filtration mode occurs. When filtering suspensions of susp ded solids cont t above some threshold (usualfy 1% by volume) cake filtration is rapidly established. Below this value other mechanisms may be present for some time. An exan le of this is illustrated in Figure 2.20.
