Abstract The case study presents a modification to the bleaching stage of pulp manufacturing. Bleached kraft pulp is manufactured by cooking, washing, and bleaching wood chips. Modification of the standard bleaching process by preceding the chlorine, caustic soda, and chlorine dioxide bleaching with oxygen bleaching will reduce the quantities of reagents and water used in the conventional bleaching process. Washing water resulting from oxygen bleaching may be used for washing the pulp after cooking. The process reduces the coloration of wastes.
