Zusammenfassung:A method of providing a diluted discharge pulp comprises the steps of providing (SIO) pulp with a first consistency in a digester (1), which pulp comprises cooked lignocellulosic fibrous material, diluting (S20) the provided pulp by feeding a reject liquor from a screening process into the digester (1) to provide a diluted pulp in the digester (1), where the reject liquor from the screening process is a pulp with a lower consistency than the pulp with a first consistency, and feeding (S30) the diluted pulp through a discharge pipe (3) to a discharge tank (2) to provide a diluted discharge pulp.
