BOD Test Explained | Principle, Procedure, Calculation & Environmental Importance
Biochemical Oxygen Demand (BOD) Explained | Definition, Principle, Procedure, Calculation & Importance Introduction Biochemical Oxygen Demand (BOD) is one of the most important parameters used to assess the level of biodegradable organic pollution in water and wastewater. It indicates the amount of dissolved oxygen required by microorganisms to biologically decompose organic matter under aerobic conditions. BOD is widely used in environmental science, wastewater treatment, water-quality monitoring, and pollution assessment. What is BOD? Biochemical Oxygen Demand (BOD) is the amount of dissolved oxygen consumed by microorganisms while decomposing biologically degradable organic matter present in a water sample under aerobic conditions. The standard BOD₅ test measures the oxygen consumed during a 5-day incubation period at 20°C. Definition BOD₅ is the amount of dissolved oxygen consumed by microorganisms during the biological decomposition of biodegradable organic matter ...
