BOD Test
1. What Factors May Effect a BOD Test?
The amount of oxygen consumption is dependent on multiple factors like pH, temperature, the type of organic and inorganic matter present in the water sample, and the type of different microorganisms .
2.What are the Limitations of the BOD Test?
The major limitations of the BOD test are:
- Any impurity in the water will affect the microbial activity of the water sample.
- The BOD does not include the non- biodegradable matter present in the sample and hence a proper estimate of the pollution level cannot be made.
3. What Happens if BOD is Low?
If the BOD value is low, the water is pure in nature as it is full of oxygen and less oxygen is being consumed by the organisms in it.
4. What is the Principle of BOD?
BOD is established on the principle that microorganisms keep consuming oxygen to decompose organic waste till the time it does not get dissipated.
5. What are the Applications of BOD?
The applications of BOD are:
- It tells us about the pollution present in the water bodies and aquatic ecosystems.
- It is used to estimate the efficiency of wastewater treatment plant.
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.
