It has been reported that a peat biofilter treating styrene bad a maximum elimination capacity of 100 g/m3-hr, and a critical load of hetween 60-75 g/m³-hr (Togna and Folsom 1992). Fur- ther investigation reveals that a 97% efficiency was achieved at a load of 40 g/m-hr. Assume that to meet a local odor ordinance you must design for at leaşt a 90% removal efficiency, Use this information to estimate the dimensions of the biofilter needed to treat 10,000 m/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 sur- face Iouding cannot exceed 1.5 m/min.
