Given:

Average flow rate = .0022 m^3 /s (190 m^3 /d) Influent Substrate concentration = 250 mg/L as COD (all essentially soluble) Mean cell residence time is to be 5 days Volume of mix tank = 25 m^3 the reactors kenetic constants are: u(max)= 2.4 d^-1 , Ks = 75 mg/L as COD, Y=.4 VSS/g COD, k(d)= .096 d^-1 (K=u(max)/Y)

a) What is the hydraulic residence time of the reactor?

b) What is the COD removal efficiency of this system?

c) What is the biomass concentration in the aeration Tank?

d) What is the F/M ratio?

e) What is the sludge production rate? Please show work
