Patent

CA 2480547

For the filtration of liquids used in, say, the food industry, use is made of filters of a polymeric substance that is resistant to chemicals and water. Filter cartridges are known which have been produced by sintering or fusing particles of said substance together and which exhibit a porous layer of specific thickness. In order to make the production of filtration plants more economical and to simplify filtration, the invention proposes that the layer (2) exhibits a structure which has progressively smaller pore sizes, as measured in the direction of flow (10), and filter aids (3) are incorporated in said porous layer (2) and are introduced into, and anchored in, said porous layer (2) by means of preconditioning.

On utilise, pour la filtration de liquides utilisés, par exemple, dans l'industrie alimentaire, des filtres en une substance polymère qui est résistante aux produits chimiques et à l'eau. On connaît déjà des cartouches filtrantes produites par frittage ou fusion de particules de ladite substance, et présentant une couche poreuse d'épaisseur spécifique. En vue d'obtenir des postes de filtration plus économiques et de simplifier la filtration, l'invention est caractérisée en ce que la couche (2) présente une structure dotée de pores ayant des dimensions qui, mesurées dans le sens de l'écoulement (10), vont progressivement en diminuant, et en ce que des auxiliaires de filtration (3) sont incorporés dans ladite couche poreuse (2) et sont introduits et ancrés dans celle-ci (2) au moyen d'un préconditionnement.
