ABSTRACT
A fiberbed filter is a wet-type collector that uses a Brownian motion capture mechanism to remove submicron liquid and solid particulate aerosols from a gas stream. Traditionally used for acid aerosol collection, fiberbeds have been used in recent years as a highly effective supplement to other wet scrubbing devices. Fiberbeds bridge the "applications gap" between wet scrubbers and dry filters. They couple wet scrubbing capture techniques with filtration techniques. CECO filters are used for the filtration of very small liquid particles from an air stream or other gas stream. Particle size distribution can be represented in several different ways. The most common method is the Frequency Distribution Curve in which the number, or weight of particles in a given size range, is plotted against the average particle size of the range. This chapter provides an excellent overview of the theory of operation of a fiberbed, its design history, and some of its applications.
