Kraft Mill Bleach Plant Effluents: Recent Developments Aimed at Decreasing Their Environmental Impact. Part 1

摘要

Recently, there has been increasing concern within the pulp and paper industry about the environmental impact of chemical compounds created in the pulping and bleaching process. We offer a review of developments in the technology of pulping and bleaching that have demonstrated new ways to decrease the formation of chlorinated organic materials. Our review also includes a look at the composition of bleach plant effluent and at the effluent treatment methods that have been studied as ways to remove chlorinated organic materials from the discharge.
