In a trickling biological filter, the BOD value of the feed stream is 
with a feed
flow of F =
The effluent BOD value is desired to be 
= 10 mg/l. The following ki-
netic parameters for the biocatalysts are known:
S/l. The
biofilm thickness is L = 0.1 mm. The cross-sectional area of the filter is A = 2
and the biofilm surface area per unit volume of the bed is 
Assume that dis-
solved oxygen is the rate-limiting substrate and the diffusion coefficient of oxygen is
Determine the required height of the bed. You can assume first-order
bioreaction kinetics.
