Question: A BOD test was performed by diluting the sample in 3 0 m L of wastewater sample was mixed with 2 7 0 m L

A BOD test was performed by diluting the sample in 30mL of wastewater sample was mixed with 270mL of diluent water. The dissolved oxygen content is 8.0mgL. After incubation for 5 days, the dissolved oxygen content was reduced to 3.2mgL. Estimate the BOD5 of the sample. (Ans: BOD5=48mgL)
