Technical Bulletin No. 0751: Experimental Stream Responses to Biologically-Treated Bleached Kraft Mill Effluent Before and After Mill Process Changes to Increased Chlorine Dioxide

Studies were carried out in outdoor experimental streams with biologically-treated bleached kraft mill effluent before and after the mill converted to increased chlorine dioxide (ClO2) substitution and then oxygen delignification (OD). Process changes resulted in significant reductions in effluent chlorinated organics. Effects were assessed by comparing parameters in streams receiving 1.
