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.

Thin films covalently bonded to cellulose ester membranes and methods of making the same

Embodiments disclosed herein are directed to methods and systems for treating wastewater via forward osmosis. By way of example, the methods and systems disclosed herein may be used to filter one or more precipitated salts and/or other particles from wastewater generated by power plants such as flue gas wastewater, oil and gas wastewater, and other industrial processes. For example, the methods and systems disclosed herein may be used to filter one or more precipitated salts from a wastewater feed concentrate formed during the forward osmosis process that is recirculated through at least one membrane module to continue the forward osmosis process. Filtering the one or more precipitated salts from the wastewater feed concentrate helps limit clogging of open channel feed spacer(s) of the at least one membrane module.
