Abstract: Washing pulp is effected in apparatus wherein the washing liquid is forced through a perforate wall into and through a body of the pulp and into a collecting space for the washing liquid. To prevent clogging of the perforate wall, the influx of treatment liquid into the collecting space is interrupted at suitable intervals, the interruption being produced by pressure variations induced by a vibrator operating in the liquid.
