Challenge Problems

Push your limits with challenges.

Question 1

A group of students conducted BOD analysis at various temperatures (15°C, 20°C, and 25°C). They found the BOD at 20°C to be 10 mg/L. Calculate the expected BOD at 25°C if it is known that for every 5°C increase in temperature, BOD increases by 20%.

💡 Hint: Use the percentage change based on temperature.

Question 2

If a water sample shows a BOD of 0 after a five-day incubation, what could be inferred about its organic load and microbial activity?

💡 Hint: Consider how the results reflect on water cleanliness and microbial health.
