Abstract Approximately 90 percent of the United States' chemical wood pulp is produced by the kraft pulping process. In spite of various measures taken to reduce pollution, kraft mill effluents discharged into streams are objectionable in color, and further improvements are needed to reduce the color of these effluents. The nature of color bodies in kraft mill effluents apparently has not been fully investigated. Presumably, two wastes are believed to be the main sources of color in the effluents; weak black liquor and effluent from the caustic extraction stages in the bleach plant. In addition, some color may form in the holding ponds. The present project has been divided into two parts. The first part has been concerned with the chemical and physical characterization of the color bodies in the mill effluents both before and after lime treatment. Effluents from two different mills were studied. Part of this report deals with the study of effluents from the International Paper Company (IPCO) mill at Springhill, Louisiana, and the Continental Can Company (CONCO) mill at Hodge, Louisiana. The second part of the project has been concerned with the lime treatment of mill effluents in the presence of multivalent ions. The objective was to establish conditions for an improved lime-treatment process using small amounts of multivalent ions of other metals in addition to lime.
