A city wants to install a reactor for the removal of contaminants. The current concentration of the contaminants in the effluent is 150 mg/L and the design flow rate is 100 gal/min. The contaminant removal rate is studied in a batch process to estimate how fast the system remove contaminants. The following data is obtained. Time (hours) Concentration (ppm)
0 50.8
7.5 32
15 19.7
22.5 12.3
30 7.6
You are asked to determine the size (i. e, volume) of the reactor that will be needed to reduce the concentration of the contaminant to 25 mg/L. Determine this for:
A) A plug flow reactor.
B) A completely mixed reactor.
C) Three CSTR reactors in series (same dimensions, find the individual reactor volume and total volume).
