Compared with the single stage bisulphite process, the two-stage bisulphite process gives higher yield, better strength, and improved bleachability. The sodium base two-stage bisulphite process gives better quality of pulp than the magnesium base and ammonium base two-stage bisulphite process. The ammonium base showed lower yield and lower strength than the other two bases. - Authors
