ABSTRACT:
The present invention relates to a lightweight and durable flexible-walled adsorber vessel that may be a freestanding unit, may be hung from an overhead support frame or ceiling, may float or be submersed in a body of liquid, or otherwise be suspended during use. The flexible adsorber of the present invention utilizes an internal screen, mesh, pallet or similar means to support carbon or other porous filter media so as to permit the pressurized or unpressurized removal of undesirable vapors, liquids or solids that may be present in streams of gas or liquid. Embodiments of the flexible adsorber are capable of supporting filter media weighing a ton or more, can resist deterioration in the presence of a variety toxic chemicals and/or corrosive agents, and can serve as a shipping container before or after use.
