Verified Answer
In which one of the following tests is the organic matter in the waste...
The correct answer is option 'A', BOD (Biochemical Oxygen Demand).
The BOD (Biochemical Oxygen Demand) test is a measure of the amount of oxygen that is consumed by microorganisms as they degrade the organic matter present in a water or wastewater sample. The test measures the decrease in dissolved oxygen (DO) in a water sample over a specific period of time (usually 5 days) at a specific temperature (usually 20�C). The test is based on the principle that the organic matter present in a water sample can be used as a food source by microorganisms, leading to a decrease in the amount of dissolved oxygen in the water. The BOD test is widely used to measure the organic pollution of surface water and to determine the efficiency of wastewater treatment plants.

In which one of the following tests is the organic matter in the waste...
Organic matter in waste water
Organic matter is one of the major components in wastewater and it is composed of various compounds such as carbohydrates, proteins, and fats. These compounds are biodegradable and can be used as a food source for microorganisms.
BOD test
Biochemical Oxygen Demand (BOD) is a measure of the amount of organic matter in water that can be oxidized by microorganisms. In this test, the organic matter in the wastewater is used as food by microorganisms, which decompose the organic matter into carbon dioxide, water, and energy. The oxygen required for this process is measured and is referred to as the BOD.
Importance of BOD test
The BOD test is an important parameter in wastewater treatment because it indicates the amount of organic matter that needs to be removed. The higher the BOD, the more organic matter is present in the wastewater, and the more difficult it is to treat. The BOD test is also used to determine the effectiveness of wastewater treatment processes and to monitor the quality of the effluent.
Conclusion
In conclusion, the BOD test is a measure of the amount of organic matter in wastewater that can be oxidized by microorganisms. This test is important in wastewater treatment because it indicates the amount of organic matter that needs to be removed and is used to determine the effectiveness of wastewater treatment processes.
