A mobile decontamination system comprises a pair of strong weathertight transportable sea containers which can be positioned side-by-side at a jobsite. One of the containers is partitioned to divide the container into separate compartments including a decontamination room, a decontamination cell room and a count room, there being normally closed doorways between the compartments. Large or heavy objects are cleaned in the decontamination room, preferably using CO.sub.2 pellets delivered under high pressure through a discharge hose. Smaller objects are cleaned in a special decontamination cell or glovebox located in the decontamination cell room. For this, CO.sub.2 pellets are delivered under high pressure through a hose to the decontamination cell. After objects are cleaned in the cell, they may be tested by monitors in the count room to verify that the objects are indeed clean. The second container houses the heavy equipment required to service the first container.

A cylindrical insert for a pre-existing pressure vessel has an integral accumulator chamber defining a head for the vessel. Inner end surfaces of the accumulator chamber, along with the walls of the pressure vessel, define a filter element chamber, the inner end of the accumulator chamber also supporting an array of permanent filter elements. The accumulator chamber is of annular form, around a central pipe which serves, alternately, as the outlet for filtered fluid passing from the filter chamber or as the inlet for filtered clean fluid to be forcefully pulsed back through the filter elements by the release of compressed air from the accumulator to flush them of an accumulation of filtered waste material. The insert system includes piping associated with the accumulator chamber for charging the chamber with highly compressed air and for selectively releasing the charge for backflushing, and control valves for placing the insert system in filtering and backflushing modes. The accumulator volume is so proportioned, relative to the volume of the system communicating therewith during backflushing, that the equilibrium pressure during backflushing cannot exceed the pressure rating of the vessel.
