A feed containing a soluble substrate with a biodegradable COD of 1000 mg/L is flowing at a rate of 100 L/hr into a 1000 L aerobic CSTR which contains a mixed community of a microorganisms. The kinetic parameters and stoichiometric coefficients characterizing the culture are given below: any four parts MiniMUM mmax=0.40 day-1 KS=120 mg COD/L YH=0.54 mg cell COD/ mg COD bH=0.08 day-1 a.) Determine the following for an SRT of 100 hr. a1) The concentration of soluble biodegradable COD in the effluent. a2) The total biomass concentration in the bioreactor. a3) The active fraction of the biomass. a4) The g/hr of oxygen which must be supplied to the bioreactor. a5) The g/hr of excess biomass that must be disposed of. a6) The mg/hr of nitrogen that will be used for synthesis of new biomass. a7) The process loading factor
