Biochemical Oxygen Demand - Affecting Factors, Significance and …
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… Webb13 nov. 2024 · Biochemical oxygen demand (BOD) represents the amount of oxygen consumed by bacteria and other microorganisms while they decompose organic matter … diamond head fee

Applications Applications for dissolved oxygen measurement include processes where the amount of oxygen affects a reaction rate or process efficiency, or indicates an environmental condition. Webb6 apr. 2024 · Biological oxygen demand affects the amount of dissolved oxygen in streams and rivers. The rate of oxygen consumption is affected by: pH, temperature, various kinds of microorganisms, and organic and inorganic materials. Less oxygen is consumed by higher forms of aquatic life.
