A BOD test is run using 60 mL of treated wastewater mixed with 240 mL of pure water. The initial DO of the mix is 9.0 mg/L. After 5 days, the DO is 3.5 mg/L. After a long period of time, the DO is 1.5 mg/L, and it no longer seems to be dropping. Assume the only BOD measured is carbonaceous. (a) (b) (c) (d) What is the five-day BOD of the wastewater? Estimate the ultimate carbonaceous BOD. What would be the remaining BOD after five days have elapsed? Estimate the reaction rate constant k (day'¹).
