Special Report No. 95-09: Characterization of Effluent Quality at Seven Canadian Kraft Mills Operating Complete Substitution Bleach Plants

In January and February of 1995, seven kraft pulp mills in Canada and NCASI cooperated in a study designed to characterize the composition of bleach plant and biologically treated effluents from complete chlorine dioxide substitution bleach plants. Effluents from nine bleach plants and five wastewater treatment plants were sampled. Analyses were conducted for twenty-eight chlorinated phenolic compounds, 2,3,7,8-TCDD and TCDF, chloroform, acetone, methyl ethyl ketone, methylene chloride, and AOX, in bleach plant effluents.
