Technical Bulletin No. 0654: Regression Models to Estimate Adsorbable Organic Halide Levels in Bleached Kraft Mill Wastewaters

Laboratory-derived data and field-measured data were used to develop a series of regression equations capable of estimating (a) AOX generation rates in laboratory-produced bleach plant filtrates, (b) AOX loading in combined untreated mill wastewaters, and (c) AOX loading in biologically treated mill effluents. A model was developed by combining these regression equations to allow the estimation of AOX loading in biologically treated effluents using specific bleach plant operating parameters as input variables.
