It has been reported that a peat biofilter treating styrene had a maximum elimination capacity of 100 g/m^3-hr,and a critical load of between 60-75 g/m^3-hr. Further investigation reveals that a 97% efficiency was acheived at a load 40 g/m^3-hr. Assume that tomeet a local odor ordinance you must design for at least a 90% removal efficiency. Use this information to estimate the demensions of the biofilter needed to treat 10,000 m^3/hr of air (at 30 C and 1 atm) containing 200 ppm styrene being emitted from a boat- manufacturing plant. Assume the bed must be at least 1 meter deep, and that the surface loading cannot exceed 1.5m/min.
