Bod test manual

depletion can be interpreted as the biochemical oxygen demand method as the B 5-Day BOD Test and the respirometric method as the D Respirometric Method (PROPOSED). The respirometric BOD is an independent method and is no longer quoted via the oxygen depletion, although it is a proposed method. 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 . Respirometric Biological Oxygen Demand (BOD) is a test that measures the quantity of oxygen consumed by bacteria that oxidize organic matter in a water sample. The test is used to measure waste loadings at wastewater treatment plants and to examine the efficiency of wastewater treatment. The instrument is sealed to prevent external atmospheric pressure.
