Design a cstr in series with the first one

Question

Problem

An organism (Zooglia ramigera) is to be used in a CSTR for wastewater treatment. It obeys Monod kinetics with μ_max = 5.5 d^-1 and Ks = 0.03 mg/dm³. A total flow rate of 100 mL/min is being envisaged at an initial pollutant concentration of 100 mg/dm³. C_X = 10 mg/L:

(a) If the desired yield factor is 0.5, what reactor volume is required?

(b) Design a CSTR in series with the first one that can reduce the pollutant concentration to 0.1 mg/dm3.

(c) If the second reactor is a PFR, what size reactor will be required in part (b)?

(d) Which combination do you recommend and why?

The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
