WebBiochemical oxygen demand (BOD) is the amount of dissolved oxygen needed by aerobic biological organisms.Dilution method is a standard method and it is recognized by EPA. BOD 5 is calculated by: Unseeded BOD 5 = (D 0 - D 5) P. Where, D 0 is the dissolved oxygen (DO) of the diluted solution after preparation (mg/l) D 5 is the DO of the diluted ... WebCalculation of BOD: 1. Subtract the five day DO reading from the initial reading from all bottles. This is the corrected value 2. Subtract the mean corrected value of the blanks from all corrected values.
