This is total BS. The BOD test is inaccurate (15% variability according to Standard Methods). Plus it can be spoofed deliberately or accidentally by introduction of non-acclimated bacteria and a host of other variables. Furthermore it is useless as a control parameter because you get the results of what you did 5 days ago, and your corrections to operations are taking a stab into the unknown.
If you want to control your operations, use COD. Sure, you can develop a relationship between COD and BOD or use published figures with reasonable accuracy. But don't try and use BOD as a control parameter. It might also be interesting to look up the history of BOD5. It was, as rumor has it, developed in England where the rivers take less than 5 days to flow into the sea.
