A cheese factory located in a normally warm state has liquid waste with the following characteristics:
Waste 1: volume is 10,000 gal/day; BOD is 1000mg/L
Waste 2: volume is 25000 gal/day; BOD is 250 mg/L
The factory will use a 4 ft deep on-site lagoon to stabilize the waste with a loading rate of 20 lb BOD/acre-day.
Part a) What is the total BOD loading per day?
Part b) What lagoon size is required?
Part c) what is the detention time?
