Abstract
We present here results for filtration experiments with
refined and fractionated chemical pulp suspensions. The
properties of consolidating fibre network are described
in terms of permeability and structural pressure. The
main objective of this work was to clarify the effect of
fibre and pulp properties on the dynamics of the
filtration and on the rheological properties of
filtrating fibre network. The relevance of coarseness,
average fibre length, fibre length distribution and
Canadian Standard Freeness on permeability constant and
structural pressure was evaluated. The filtration
properties could be correlated with fines fraction and
coarseness of fibres.
