Technical Bulletin No. 0070: BOD from Oxygen-consumed Determinations

  The oxygen-consumed test for determining the oxygen demand of effluents has a decided advantage over the BOD test in that it can be completed in a short period of time and requires less equipment and manipulation. In the course of a number of laboratory and pilot plant investigations on the treatment of kraft mill effluents considerable comparative data were collected. These were assembled, tabulated and analyzed by Mr. Herbert F. Berger, who is attached to the Council’s Virginia Polytechnic Institute Project, for the purpose of determining what relationship, if any, the oxygen-consumed value for kraft mill effluents had to the BOD value. Such relationship determines to what degree one test can be substituted for the other and under what specific conditions. The enclosed report contains the analysis of the comparative data and the conclusions reached.
