In wastewater treatment, what does BOD stand for?

Explanation:
Biochemical Oxygen Demand measures how much oxygen microbes will use to biologically oxidize organic matter in water under defined conditions. This is the standard expansion for BOD: Biochemical Oxygen Demand. The term emphasizes the biological oxidation process driven by microorganisms. The other options don’t fit the established terminology: Biological Oxygen Demand isn’t the official wording, Bacteria Oxygen Depletion is inaccurate, and Basic Oxygen Demand is incorrect. In practice, BOD is a key indicator of wastewater strength and is often measured as BOD5 (oxygen used in five days at 20°C).
