Abstract
A disposable paperboard container for holding a bed of solid filtration media is disclosed. The container is strong enough to prevent excessive pillowing, has sufficient open area to minimize the pressure drop across the bed, avoids bypass gaps caused by settling of media, is made of environmentally safe disposable materials which do not react with the media or absorb excess moisture, and is inexpensive enough to be discarded rather than refilled. In accordance with other aspects of the invention, space within a media container created by settling is automatically occupied by expandable plugs to prevent bypass. Container units embodying the invention may be combined to form filtration modules which are strong, yet light enough to be handled easily.
