Abstract

A process for treatment of lignocellulosic pulp comprising a multistage washing of the unbleached kraft brown stock and a xylanase treatment. The xylanase treatment is carried out in a holding tank introduced upstream the first washing unit or downstream one or more of the other washing units except for the last washing unit.
