Title (EN) MULTILAYER DEPTH FILTER WOUND FROM SINGLE MEMBRANE
(FR) FILTRE
Abstract:
(EN) A membrane filter comprises a plurality of porous layers having successively decreasing mean pore sizes. In one embodiment, the layers are formed from the same membrane which is wrapped in a cylindrical fashion. Also disclosed is a method of manufacturing a membrane filter comprising wrapping a porous membrane or film in an overlapping cylindrical fashion and controlling the pore size by controlling the torque during the wrapping.
(FR) Filtre à membrane comprenant une pluralité de couches poreuses ayant des tailles de pore moyennes successivement décroissantes. Selon un mode de réalisation, les couches sont formées à partir de la même membrane qui est enroulée de manière cylindrique. L'invention concerne également un procédé de fabrication d'un filtre à membrane comprenant l'enroulement d'un film ou membrane poreux de manière cylindrique en chevauchement et la commande de la taille de pores par la commande du couple pendant l'enroulement.
