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
The specific surface area of the biofilm in the reactor is 
Assuming
first-order reaction kinetics and an average effectiveness factor of
throughout the col-
umn, determine the required height of the column for effluent total carbon concentration of
