Abstract The filtration of pulp suspension is one of the key papermaking processes. It is measured using many kinds of analyzers and modeled using both physical and empirical mathematical expressions. The main target of this thesis was to develop an empirical mathematical model to describe the filtration of a drainage analyzer. In this work the diameter of the screen (10 cm), as well as the amount (1000 cm3), consistency (0.3%) and temperature (20 ˚C) of the sample were (about) the same as those of the Canadian Standard Freeness analyzer. The analyzer was equipped with the measurements of filtrated volume, driving pressure and filtrate consistency. The pressures from the underpressure of 80 kPa to the overpressure of 80 kPa could be used....
