Abstract
In a pulp washing system where there is substantially constant average weight of pulp mat (on a dry pulp basis), washing uniformity is improved by controlling the weight per unit area of liquid alone or liquid and pulp combined in the pulp mat across its width to obtain a substantially constant distribution of selected property in the pulp mat across its width. This is accomplished by steps comprising determining the property in a plurality of selected locations across the width of the pulp mat and also the average value of the property across the width and controlling dilution liquid input into the headbox in response to the determination to produce of substantially constant distribution of the property across the width of the mat.
