Abstract |
This report presents a survey of the literature and other sources on present practices and advanced methods of handling and treatment of pulp and paper mill effluents, with particular emphasis on the kraft process, and the use of activated carbon and lime treatment as advanced methods of treatment. The survey was made as a first step of a development program aimed at maximum water reuse in kraft pulp and paper mills based on effluent treatment using activated carbon. The results of the survey include information on activated carbon and its applications in treatment of pulp and paper mill effluents as well as in treatment of municipal water supplies and effluents. Information is presented on lime treatment of kraft mill effluent and on other advanced treatment methods. It also covers the subjects of in-plant water reuse, effluent collection systems, solids removal, and biological oxidation. (Author) |
