Zusammenfassung:Embodiments disclosed herein are directed to membranes for filtration, methods of manufacturing the same, and membrane modules incorporating the same. In an embodiment, a membrane is disclosed. The membrane includes a porous cellulose layer, a polyamide thin film layer bonded to the porous cellulose layer, and a fabric support layer that supports the porous cellulose layer and the polyamide thin film layer. The porous cellulose layer has a pore size of about 30 nm to about 500 nm at an exposed surface of the porous cellulose layer.
