چکیده مقاله
Forward osmosis FO has attracted enormous research interests as a prospective low energy membrane separation technology in many potential applications such as desalination and wastewater treatment The novel thin film nanocomposite TFN FO membranes have demonstrated great improvement in separation performance and antifouling capacities Furthermore, the utilization of thin film composite TFC FO membranes has brought to light substantial enhancements in the separation process Zinc oxide ZnO serves as an interlayer, effectively regulating the interfacial polymerization IP process to achieve the formation of a dense polyamide PA selective activelayer In this study, we embarked on the production of TFC FO membranes, incorporating a ZnO interlayer sandwiched between the sublayer PES and the PA layer The design of nano sheets interlayer between the substrate and polyamide layer has attracted growing attention to improve the performance of thin film composite membranes Remarkably, the enhancement of hydrophilicity was obtained through contact angle analysis To ensure the precision of ZnO nanoparticle synthesis and gain information about the membrane's surface and cross sectional characteristics, as well as the mechanism underlying the formation of the PA layer, we used the FESEM analysis The TFC/ZnO membrane possessed a higher water flux of 241146 L m 2 h 1 accompanied with a salt rejection rate of 991 99 These impressive results were achieved when employing a feed solution of 44 mM NaCl and a draw solution of 2 M NaCl This work provides a new strategy to fabricate the TFC membranes on sublayers for FO processes These membranes promise to offer exceptional perm selectivity, effective control over concentration polarization CP phenomena, and the anticipated enhancements in the separation process
