Abstract
A pulp preparation process in which pulp treatment is expanded to include in-digester treatments (Figures 7, 8, 9) previously performed outside of the digester (12) in discrete process equipment. Specifically, a manner for in-digester bleaching is disclosed, preferably using non-chlorine containing bleaching reagents.
