   Dec 12, 2023 · Biochemical Oxygen Demand (BOD) can be defined as the amount of dissolved oxygen required by microorganisms to digest organic waste present in one liter of water. The more organic waste dissolved per liter, the more the BOD. It is an important parameter used to measure the amount of pollution in water bodies.

   May 7, 2024 · Biochemical/biological oxygen demand (BOD) is measured using the following formula: BOD = (DO1 – DO2) * dilution factor/volume of the sample (if used). Dissolved oxygen (DO) is measured at the beginning (DO1) and then after a 5 day period (DO2) at 68°F (20°C).

   What does BOD 5 mean?

   • The difference in dissolved oxygen level between the beginning and end of the test gives the BOD 5 (i.e. the 5-day biological or biochemical oxygen demand), which is typically expressed in units of mg/L (milligrams dissolved oxygen per litre of water). There are dilution factors and control samples to take into account, but that’s a general idea.

   What does BOD 5 mean in water quality test?

   • It is not a precise quantitative test, although it is widely used as an indication of the organic quality of water. It is most commonly expressed in milligrams of oxygen consumed per liter of sample during 5 days (BOD 5) of incubation at 20°C and is often used as a robust surrogate of the degree of organic pollution of water.
