A method and apparatus for removing and disposing of contaminants from a contaminated fluid makes use of an expendable collection receptacle which is encapsulated in an inert protective matrix except for inlet and outlet ports and which is capable of removing and retaining contamination from the liquid when passed therethrough. The removed and retained contamination is subsequently encapsulated in a solid material within the receptacle by introducing a settable fluid material into the receptacle. The inlet and outlet ports are then encapsulated in a solid inert matrix so that the receptacle can be disposed of.

In a process for continuously treating contaminants contained in a fluid, for the purpose of their final disposal, comprising providing at least one expendable collecting receptacle which has an inlet port and an outlet port and which is totally encapsulated with a solid inert mass except for the ports, purifying the fluid by at least one operation which includes treating the fluid to remove contaminants therefrom and retaining the contaminants in said collecting receptacle, the fluid having been passed into said collecting receptacle through said ports, and subsequently encapsulating the ports in a solid inert mass, the improvement of (a) placing the collecting receptacle in an open top container of substantially greater size than the collecting receptacle, and totally encapsulating the collecting receptacle except for the ports with said solid inert mass which is added to the container before purifying the fluid, so as to completely surround the collecting receptacle up to a level above the top of the collecting receptacle and below the ports and the top of the container, said mass functioning as a biological shield, or as a coating resistant to chemical attack and mechanical stress, or as a biological shield and as a coating resistant to chemical attack and mechanical stress, and (b) rendering insoluble the contaminants within said collecting receptacle by passing into said receptacle in a continuous way through said inlet port with excess passing out through said outlet port, after purifying the fluid and before encapsulating the ports, at least one substance which solidifies to a solid matrix therefore rendering the contaminants insoluble within said collecting receptacle.
