The viscosity of paper pulp is maximized, while chlorine bleaching is minimized or eliminated, by subjecting the pulp suspension to multiple consecutive oxygen bleaching stages, with a countercurrent wash between O2 stages. A chelating agent -- such as EDTA -- may be added to the countercurrent wash liquid, and/or another chelating agent -- such as DTPA -- may be used to pretreat the pulp.
