Comparative analysis of upward/downward filtration and expression using a consolidation cell
Filtration behavior is influenced by particle settling in a slurry. In a downward filtration, an additional cake derived from settling particles increases filtration resistance. In an upward filtration, on the other hand, the particle settling leads to dilute the slurry near the filter medium,...

| Summary: | Filtration behavior is influenced by particle settling
in a slurry. In a downward filtration, an additional
cake derived from settling particles increases
filtration resistance. In an upward filtration, on the
other hand, the particle settling leads to dilute the
slurry near the filter medium, resulting in a decrease
of filtration resistance. Iritani et al. have proposed an
analytical method for filtration considering the
effects of particle settling [1]. When a slurry is
filtered in a consolidation cell which has upper and
lower drainage surfaces (Fig.1), both phenomena
mentioned above seem to occur simultaneously.
In this study, the validity of the filtration properties
obtained from expression test using the consolidation
cell were examined. |
