Abstract
In this work, a novel experimental filtration device with
pressure profiling was used for analyzing water removal
from the fiber network in the forming section of a paper
machine. The experimental data were used to develop a
stratified model for the flow resistance of the
developing fiber sheet during the filtration process. The
new model was verified with both laboratory- and
pilot-scale measurements and excellent agreement was
observed between them. It was also observed that there is
a strong linear correlation between the maximal
attainable solid content of a filtered sheet after the
forming section and the instantaneous response to
pressure of the flow resistivity of the furnish.
