Abstract
Pulp washing efficiency at any given dilution factor and production rate is maximized by controlling washing surface speed in response to determination of total mass of product stream in weight per unit area on the surface and simultaneously controlling the rate of dilution liquid introduction in response to sensing of feed level in the container feeding the surface, thereby to obtain a substantially constant level of pulp in the feed and in the pulp mat formed on the washing surface which is to undergo washing and a substantially constant weight of pulp mat (on a dry pulp basis) per unit area on the washing surface.
