The BOD values for pure water and highly polluted water are respectively
- A \(\gt 5 \mathrm{ppm}, \leq 17 \mathrm{ppm}\)
- B \(\gt 5 \mathrm{ppm}, \geq 17 \mathrm{ppm}\)
- C \(\lt 5 \mathrm{ppm}, \geq 17 \mathrm{ppm}\)
- D \(\lt 5 \mathrm{ppm}, \leq 17 \mathrm{ppm}\)
Answer & Solution
Correct Answer
(C) \(\lt 5 \mathrm{ppm}, \geq 17 \mathrm{ppm}\)
Step-by-step Solution
Detailed explanation
BOD (Biological oxygen demand) is less than 5ppm in clean water, where as highly polluted water have a BOD value of 17 ppm and more. \(< 5 \mathrm{ppm} \geq 17 \mathrm{ppm}\)
