UO concentration decreases to 2.4 mg/L after 5 days of incubation,
a. calculate the 5-day BOD concentration in mg/L:
b. If the wastewater degrades at a rate of 0.22/day, what is the ultimate BOD concentration?
c. Based on the k value in part (b), what would the BOD concentration be after 10 days?
d. What other factor may influence the BOD that is not accounted for in part (c)?
2nYour consulting firm is doing an expansion project for a drinking water treatment
plant in a growing urban area that has a current population of 55,000 people and treats 20 MGD.
If there is 2.8% population growth, continuously compounded, and you want the expansion to be
able to serve the urban area for the 35 year design life of the upgraded facility, what should the
new design capacity (in MGD) of the treatment plant be?
can you show me step for step?
