3. Suppose you are to measure the BOD removal rate for a primary wastewater treatment plant. You take 2 samples of raw sewage on its way into the plant and two samples of the effluent leaving the plant. Standard 5-day BOD tests are run on the four samples, with no seeding producing the following data: Sample DOi (mg/L) DOf (mg/L) TEP Source Dilution 1 Raw 1:30 9.0 2.2 2 Raw 1:20 9.0 3 Treated 1:15 8.5 1.5 4 Treated ? 9.0 1 a. Find the BOD5 for the raw and treated sewage, and the percent removal of BOD in the treatment plant. b. Find the DO that would be expected in sample 2 at the end of the test. c. What would be the maximum volume of treated sewage for sample 4 that could be put into the 300 ml BOD bottle and still have the DO after 5 days remain above zero?
