WebbTheoretical oxygen demand (ThOD) is the calculated amount of oxygen required to oxidize a test chemical to its final oxidation products. When the BOD is more than 60% of the ThOD, and the amounts of the chemical and its degradation products are less than 1% of the added chemical, ... WebbBiochemical oxygen demand (BOD) is a measure of the dissolved oxygen consumed by microorganisms during the oxidation of reduced substances in waters and wastes. Typical sources of BOD are readily biodegradable organic carbon (carbonaceous, CBOD) and ammonia (nitrogenous, NBOD).

Theoretical oxygen demand (ThOD) is the calculated amount of oxygen required to oxidize a compound to its final oxidation products. However, there are some differences between standard methods that can influence the results obtained: for example, some calculations assume that nitrogen released from organic compounds is generated as ammonia, whereas others allow for ammonia oxidation to nitrate. Therefore, in expressing results, the calculation assumptions shoul…
