Technical Bulletin No. 0191: Temperature Relationships in Aerobic Treatment and Disposal of Pulp and Paper Wastes

  Although oxidation rates over a wide temperature range are well established for the biochemical oxygen demand (BOD) test, relatively little data were available on the effect of temperature on BOD removal processes under controlled conditions. This was particularly the case for storage oxidation basins subjectto freezing in winter From the results obtained it appeared that high BOD reductions could be maintained in aerated basins at temperatures as low as 2OC and that very high reductions are obtainable at this level if the detention period is extended beyond that required to produce similar removals at higher temperatures.
