It appears that there is a substantial misunderstanding of the BOD. It is a measure of the oxygen consumed (respiration) by bacterial acclimated to a particular waste stream. The word acclimated in one of the most important parts of the definition. In order to get a correct measure, one needs a seed bacteria acclimated to the waste stream. I would suggest that you may want to look up the definition in Standard Methods by AWWA, WEF, etc. It may also be in SW846 but I'm less sure of that location.
