Title (EN) GAS FILTERING GEOMEMBRANE
(FR) GÉOMEMBRANE DE FILTRATION DE GAZ
Abstract:
(EN) The present disclosure relates to a gas filtering device that allows to cover and filter gases emanating from liquid and/or solid substances without the use of auxiliary technologies. The gas filtering device comprises an air tight geomembrane that is adapted to cover and seal the surface from which the gas emanations come from, one or more air permeable filtering cartridge pocket(s) embedded within the air tight geomembrane that are adapted to adopt an opened configuration and a closed configuration, and one or more corresponding filtering cartridge(s) that are releasably secured within the air permeable filtering cartridge pocket.
(FR) La présente invention concerne un dispositif de filtration de gaz qui permet de recouvrir et de filtrer des gaz émanant de substances liquides ou solides sans utiliser de technologies auxiliaires. Le dispositif de filtration de gaz comprend une géomembrane étanche à l'air conçue pour recouvrir et sceller la surface d'où proviennent les émanations de gaz, une ou plusieurs poches de cartouche de filtration perméables à l'air enchâssées à l'intérieur de la géomembrane étanche à l'air et conçues pour adopter une configuration ouverte et une configuration fermée, et une ou plusieurs cartouches de filtration correspondantes fixées de manière amovible à l'intérieur de la poche de cartouche de filtration perméable à l'air.
