Consider a well-mixed waste treatment system for a small-scale system. The system is operated with a reactor of 1000 l and flow rate of 100 l/h. The separator concentrates biomass by a factor of 2. The recycle ratio is 0.7. The kinetic parameters are µ_m = 0.5 h^-1 , K_s = 0.2 g/l, Y ^M _X/S = 0.5 g/g, and kd = 0.05 h^-1 . What is the exit substrate concentration?
