BOD (Biochemical Oxygen Demand) / Respirometer

Biochemical oxygen demand (BOD) refers to the amount of oxygen required for the biochemical stabilization of degradable substances in water by aerobic microorganisms. It is generally expressed as the amount of oxygen consumed (O) over a period of five days at 20°C, measured in mg/L, and is used as an indicator of water pollution by organic substances. In addition to being measured as a comprehensive indicator of pollution in rivers and lakes, it is also measured as a water quality management parameter for effluents such as industrial wastewater.
