In municipal sewage, BOD values (in ppm) are
- A \(1-5\)
- B \(100-4000\)
- C \(50-90\)
- D 20-40
Answer & Solution
Correct Answer
(B) \(100-4000\)
Step-by-step Solution
Detailed explanation
The amount of oxygen required by bacteria to break down the organic matter present in a certain volume of a sample of water is called biochemical oxygen demand (BOD). The amount of BOD in the water is a measure of the amount of organic material in water in terms of how much…
