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… WebbTranslations in context of "Demande Théorique" in French-English from Reverso Context: Dans la présente recherche, les auteurs ont développé les concepts de Demande Théorique et Demande Pratique et propose une méthodologie facile pour leur estimation.
