Question 5.1

Constant pressure filtration - scale up


A pilot experiment used a filter of 0.1 m2 area at a constant pressure of 68.5x104 Pa. The filtrate viscosity was 0.0015 Pa s, slurry concentration was 3% w/w, cake concentration was 52% w/w and the liquid density was 1000 kg m-3.

Note moisture ratio is defined as: wet cake (or a sample therof) divided by dry cake (or the sample).


The moisture ratio was - hint consider 100 kg of wet cake:

  a) 0.52
b) 1.92
c) 1
d) 0.30
