You are the lead engineer on a wastewater treatment plant with a biological reactor. You are required to determine how much biomass will be produced in kg per day in your plant. A junior engineer determines the ultimate BOD of the incoming waste as 600 mg/l, with a decay constant of 0.1/d. The incoming substrate concentration used should be the five-day BOD. The incoming flow is 75 m3/d however there are losses upstream of the plant accounting for 15 m3/d of the flow. The target BOD discharged from the plant is 25 mg/l. the kinetic constants for the system are Ks = 90 mg/L BOD5, kd = 0.2 d-1, μm = 1.5 d-1, and Y = 0.6 mg VSS/mg BOD5. Include a sketch to illustrate the biological reactor and its incoming flows.
