Abstract

Membrana y Proceso de separación por osmosis directa que comprende proveer una membrana de osmosis directa, en donde el paso de proveer la membrana de osmosis directa comprende: - Proveer una estructura de soporte que comprenda un sustrato de bicapa que incluya una primera y una segunda capas separables, donde la primera capa tiene un grosor de menos de 2 mils (50,8 um); - Aplicar un material a la primera capa del sustrato bicapa de la estructura de soporte para formar una capa de soporte de membrana; - Aplicar un material de barrera que comprende una poliamida a la capa de soporte de membrana vía polimerización interfacial para formar la membrana de osmosis directa; y - separa la segunda capa del sustrato bicapa de la primera capa del sustrato bicapa para formar la membrana de osmosis directa; - Introducir una fuente de una solución de extracción a un primer lado de la membrana; e - Introducir una fuente de una solución de alimentación a un segundo lado de la membrana.
