ABSTRACT:
A method for manufacturing a filter cartridge by polymerization of a polyethylene hydrocarbon with granular elements are set forth. The method involves the preparation of a mixture comprising the hydrocarbon and the granular elements, then introduction of the mixture into a mold which is formed by a first porous wall and a second porous wall, these walls being connected to a jacket, the introduction of the mold in an oven so as to raise the temperature of the mixture and by a thermal polymerization reaction to transform the hydrocarbon into a material binding the granular elements of the mixture, the assembly of the material and granular elements then forming a cartridge, and injection of a chemically inert gaseous composition into the mold through one of the walls to impart fluid permeability to the cartridge.
