Molecular weight distributions of total organic halide in an aerated stabilization basin treating paper and pulp wastewater

Abstract

This report discusses the research and results of the study done to characterize total organic halide (TOX) distributions by apparent molecular weight (AMW) of combined effluents from a mill employing the Kraft pulp process. AMW distributions of TOX and total organic carbon (TOC) are examined at five locations within an aerated stabilization basin (ASB). An effort is made to explain experimental methods used for separation into AMW ranges and analysis for the described parameters. TOX and TOC results are tabulized and discussed. Degradation pathways of chlorinated organic compounds are examined using data from three sample sets. Analyses of the data for TOX and TOC are included and implications from this data discussed. Improvements for further analysis of future samples are incorporated in this report.
