Question

An aerated bench-scale reactor is used to evaluate a non-recycle, secondary biological process. The initial substrate concentration is 150 ppm, the final substrate concentration is 10 ppm and the initial cell concentration is 1,500 mg/L. What is the initial specific substrate utilization rate, in g/g⋅d, when the maximum specific growth rate is 3.0 1/d, and the half-saturation constant is 60 mg/L?
