In a fluidized-bed biofilm reactor, cells are attached on
spherical plastic particles to form biofilms of average thickness L = 0.5 mm.
The bed is used to remove carbon compounds from a waste-water stream. The feed
flow rate and concentration of total fermentable carbon compounds in the feed
are F = 2 l/h and S = 2000 mg/l. The diameter of the column is 10 cm. The
kinetic constants of the microbial population are rm = 50 mg S/cm3.
h and KS = 25 mg S/cm3 . The specific surface area of the
biofilm in the reactor is 2.5 cm2 /cm3 . Assuming
first-order reaction kinetics and an average effectiveness factor of n = 0.7
throughout the column, determine the required height of the column for effluent
total carbon concentration of S0i = 100 mg/l.
