PROCESS FOR BLEACHING PULP IN CONJUNCTION WITH ADSORPTION OF METALS

摘要

The following invention relates to a process for bleaching pulp, in which, after defibration, a first filtrate (2) containing metals, principally in ionic form, is separated off from pulp, in which the separated metals are supplied to a certain fibre quantity (1), which adsorbs the metals, which fibre quantity, during its further treatment, is at least not significantly negatively affected by the presence of the metals.
