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.
