Treat for a capacity of 100 MGD.
Although primary and secondary sedimentation is responsible for the removal of some BOD, you will design a bioreactor which removes 85% of BOD entering the plant using an activated sludge bioreactor. Use the following values: Influent (to bioreactor) BOD5 = 400 mg/L; Ks = 60 mg BOD5/L; kd = 0.06 day-1; µm = 3 day-1; Y = 0.6 mg VSS/mg BOD5.
(a) What must the hydraulic detention time be in the aeration pond?
(b) What mass of microbes will be produced in the pond each day?
An airport corridor is 30 ft wide. given a peak demand of 300 pedestrians per minute and an average walk speed of 3 ft/s, estimate the LOS at the corridor
