4) BOD5 measurement a. What is the standard procedure of BOD5 measurement, describe the key steps. b. what sample volume(s) should be used if the anticipated BOD5 is about 200 mg/L? c. if your DO reading on day 5 is about 0, what may cause this? what is the possible solution to solve this? Can you still use this number for BOD5 calculation? d. One aeration tank in a wastewater treatment plant does not function well (BOD is not well removed). You are asked to measure the BOD5 of the water sample collected from the tank. What dilution are you going to use to test this sample? 4) BOD5 measurement a.
