Objectives of BOD Testing
The following are the objectives of BOD:
- BOD is used to measure the level of pollution in a water body. The level of BOD is directly proportional to the amount of pollution.
- BOD gives an estimate of the overall health of a water body. If the BOD level is High, the organisms are getting deficient levels of oxygen, including plants and animals.
- Investigating the BOD levels at different points in the water body can help pinpoint the source of pollution.
- Wastewater treatment aims at improving the water quality of a particular water body. By comparing the BOD value of influent and effluents, it becomes easier to estimate the efficiency of wastewater treatment.
- Frequent BOD tests help companies and other industries to remain compliant with the pollution levels that are allowed for a water body.
- BOD Testing helps in research on marine ecosystems and how it gets affected by pollution and other factors.
What is BOD Test?
The BOD test acts as an important criterion for knowing the health of an ecosystem. The BOD Test of Water is done to know how impure or pure the water body is. The BOD test procedure involves the collection of the water sample in an air-tight container which is then kept in incubation for five days at 20 ℃. The sample of water contains microorganisms that have the function of decomposing organic matter. They utilize oxygen present in the water to do so. BOD measures the amount of oxygen that gets consumed.
