Abstract (en)
[origin: WO2014178780A1] A method and system for washing cellulose pulp are provided. The pulp is washed two times in the same washing space of a washing apparatus (10) with a movable permeable processing surface (11), filtrate from the pulp passes through the processing surface as the pulp is transported together with the processing surface. There is an intermediate pulp storage (20) connected to the washing apparatus (10) and arranged to store the pulp between the two washing operations (I, II).
