Embodiment Construction
[0029] exist figure 1 The fluid decontamination product 10 schematically and partially represented in FIG. 2 comprises a porous body 12 having an inner and an outer specific surface 14, such as a surface that brings a large filtration capacity to the porous body. In a preferred embodiment of the invention, the porous body comprises carbonaceous components such as carbon granules or carbon powder, for example graphite with an average particle size of 0.5-1 mm in the form of flakes or rods, activated carbon, fabrics or fibers of activated carbon or these combination of components. It may also contain other components, especially silicon-containing components, such as sand or zeolites. Without special treatment, this porous body already has filtering effect, but not bactericidal or bacteriostatic effect.
[0030] in references such as figure 2 After a treatment as will be described in detail, the product 10 also comprises a metallization layer 16 of at most nanoscale thicknes...

Abstract
The invention relates to a product (10) for removing pollutants from a fluid, comprising a porous body (12) having a specific outer and inner surface (14), as well as a metallized layer (16), the thickness of which is at most nanoscale, covering at least one portion of the specific outer and inner surface (14) of the porous body (12). The metallized layer (16) includes at least one metal (Ag) bonded to the porous body (12) by chemical bonds (18) resulting intramolecular forces. Further, the metallized layer (16) includes silicon (Si) also bonded to the porous body (12) by chemical bonds (18) resulting from intramolecular forces. The method for obtaining the product (10) for removing pollutants comprises a step (102) of treating a porous body (12) having a specific outer and inner surface (14) in an inert gas plasma deposition reactor (24) with radiofrequency discharge, by immersing the porous body (12) into the plasma and injecting metal (Ag) into the plasma. The step (102) of treating the porous body also comprises an injection of silicon (Si) into the plasma.
Description
technical field [0001] The present invention relates to decontamination products for fluids. The invention also relates to methods for obtaining such products. Background technique [0002] Water decontamination products that function by filtration are known. For example activated carbon, sand and other porous bodies have a very good filtration capacity due to their large internal and external specific surface (enabling large adsorption). The main disadvantage of these products results from the fact that they do not have a bactericidal or at least bacteriostatic effect combined with their simple mechanical filtration capabilities. On the contrary, they even appear to be ideal breeding grounds for bacteria and do not ensure the potability of filtered water. They therefore cannot dispense with the addition of chemical disinfectants (chlorine, peroxides, etc.) during water treatment. [0003] Products for the germicidal treatment of water consisting of activated carbon impr...
