Calculate the temperature downstream of a waste discharge outfall if the discharge flow rate is 12 MGD and its temperature is 26C, and you estimate the receiving water has a flow rate of 3.5 m /s and a temperature of 15.7C under low flow conditions (your worst-case scenario). Your Answer: Answer units
15 mL of raw wastewater wasadded into a 300-mL BOD bottle, which was then filled up with 285 mL pure water. The DO concentration in the mixed sample before incubation is 7.8 mg/L. The sample wasincubated for 5 days and the final DO wasfound to be 2.4 mg/L. What is theBOD5of the raw wastewater?
A standard BOD test is run using seeded dilution water. The blank bottle containing the seeded dilution water has an initial DO of 9.2 mg/L and a final DO of 8.2 mg/L. The waste sample is mixed with seeded dilution water at a 1:25 ratio. It has an initial DO of 9.0 mg/L and a final DO of 2.0 mg/L. Calculate the BOD5.
