ABSTRACT:
In treating effluent from an integrated paper mill having bleach plant effluent (including kraft mill effluent) and paper mill effluent (including effluent from a mechanical pulp mill) it has been found that if the two effluents are separately biologically treated and the recycled activated sludge directed to treatment of the bleach plant kraft mill effluent contains a significant portion of activated sludge derived from the treatment of the paper mill effluent that a significantly higher percentage of the absorbable organic halogens (AOX) can be removed from the bleach plant effluent.
