Abstract
Filtration characteristics of slurries with varying concentration under constant applied pressure were studied. The problem was investigated by considering addition of feed slurry to a filtration chamber initially containing particulate free liquid.
Theoretical analyses of two limiting cases of perfect displacement and complete mixing are presented. Constant pressure filtration experiments on Westex talc designed for variable slurry concentration under complete mixing conditions confirm theoretical predictions.
Analyses of experimental data ignoring the variations in slurry concentration would be incorrect and would lead to erroneous results. Based on theoretical conclusions, a method of analysing experimental data under such conditions is presented.
