Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCEDIMIENTO PARA LA FABRICACION DE MEMBRANAS DE OSMOSIS INVERSA Y A MEMBRANAS PRODUCIDAS POR EL. LA OSMOSIS INVERSA ES UN PROCESO EN EL QUE SE APLICA PRESION, EN EXCESO DE LA PRESION NETA, A UNA SOLUCION EN CONTACTO CON UNA MEMBRANA PARA FORZAR EL DISOLVENTE, PERO NO EL SOLUTO, A TRAVES DE LA MEMBRANA. ENTRE LAS APLICACIONES COMERCIALES DE UN PROCESO DE ESTA CLASE PUEDEN MENCIONARSE LA DESALINIZACION DE AGUA SALADA PARA HACERLA POTABLE, EL TRATAMIENTO DE AGUAS RESIDUALES Y AFLUENTES INDUSTRIALES Y LA CONCENTRACION DE SOLUCIONES O SUSPENSIONES TERMOSENSIBLES Y OTRAS (POR EJEMPLO, SOLES Y LATICES).
