| description | LA INVENCION SE REFIERE A UNA MEMBRANA DE OSMOSIS O DE NANOFILTRACION Y A SU PROCESO DE FABRICACION. ESTA MEMBRANA COMPRENDE UN SOPORTE POROSO DE SUSTANCIA INORGANICA REVESTIDO SOBRE UNA CARA DE UNA PRIMERA CAPA MESOPOROSA DE MATERIAL INORGANICO, POR EJEMPLO DE TIO2, QUE TIENE UN RADIO MEDIO DE PORO INFERIOR A 10 NM, Y DE UNA SEGUNDA CAPA ACTIVA, QUE TIENE UN ESPESOR DE 0,1 A 1 (MU)M, REALIZADO EN POLISULFONA SULFONADA, POLIBENCIMIDAZOLONA, POLIFLUORURO DE VINILIDENO INJERTADO O NAFIONR.
PCT No. PCT/FR91/00826 Sec. 371 Date Apr. 21, 1993 Sec. 102(e) Date Apr. 21, 1993 PCT Filed Oct. 21, 1991 PCT Pub. No. WO92/06775 PCT Pub. Date Apr. 30, 1992.The invention relates to a reverse osmosis or nanofiltration membrane and to its production process. This membrane comprises a porous support made from an inorganic material coated on one face with a first mesoporous inorganic material layer, e.g. of TiO2, having a mean pore radius below 10 nm and a second active layer, having a thickness of 0.1 to 1 mu m, made from sulphonated polysulphone, polybenzimidazolone, grafted polyvinylidine fluoride or Nafion. |
