5 days-biochemical oxygen demand (BOD5) is taken at a temperature of
A. 0°C
B. 15°C
C. 20°C
D. 25°C
Answer: Option C
Solution (By Examveda Team)
In waste water engineering, the 5-day biochemical oxygen demand (BOD5) test is typically conducted at a temperature of 20°C. This specific temperature is considered standard for measuring the amount of dissolved oxygen consumed by microorganisms during a 5-day incubation period.Therefore, the correct completion is: "5 days-Biochemical Oxygen Demand (BOD5) is taken at a temperature of 20°C."
