Abstract

Methods for treating a fibrous suspension are disclosed, including cleaning the fibrous suspension in a screening room with a plurality of cleaning stages and including a final cleaning stage, and in which the cleaning takes place at a low fiber concentration, and recycling at least a partial flow of the accept from the last cleaning stage to a position before or in the screening room after it passes through a thickener, where the concentration of the accept is increased to a concentration which minimizes dilution of the concentration of the fiber suspension, to which the accept is supplied.
