A system and a method for treating a fibrous suspension, which is cleaned in a screening room comprising a plurality of cleaning stages and with a last cleaning stage, in which the cleaning takes place at low fiber concentration, and where at least a partial flow of the accept from the last cleaning stage at recycling to a position before or in the screening room passes through a thickener, where the concentration of the accept is increased to a concentration, which minimizes the dilution of the concentration of the fiber suspension, to which the accept is supplied.
