Methods TFC membranes were synthesized by microfluidic interfacial polymerization of polyamide (PA) on polysulfone hollow fiber (HF) membrane modules. A total of 33 HF membrane modules were prepared with different number of HFs (from 1 to 25) and different lengths (from 10 to 50 cm). They were evaluated in a nanofiltration operation in terms of water permeance and rose Bengal (RB) and MgSO4 rejections. Significant findings Among the 33 modules, 73% showed RB rejections higher than 95%, while 36% of the modules reached rejections above 99%. During the membrane synthesis, different parameters, such as PA monomer concentration, residence time and reaction time, were studied. As a result, the amount of monomer was reduced by ca. 80%. The versatility of microfluidics allowed incorporating hydrophilic metal-organic framework (MOF) ZIF-93 to produce HF modules with PA/MOF bilayered membranes (a continuous layer of MOF between the support and the PA film) which led to an important enhancement of the water permeance from 1.3 (bare PA membrane) to 5.3 L·m−2·h−1·bar−1 (PA/ZIF-93 HF membrane), maintaining RB rejection above 95%. info:eu-repo/grantAgreement/ES/DGA/T68-23R info:eu-repo/grantAgreement/EC/H2020/862330/EU/Open Innovation Test Bed for nano-enabled Membranes/INNOMEM This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 862330-INNOMEM info:eu-repo/grantAgreement/ES/MINECO-AEI/PID2019-104009RB-I00-AEI-10.13039-501100011033 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 5.5 2023 ENGINEERING, CHEMICAL 31 / 170 = 0.182 2023 Q1 T1 0.849 2023 Chemistry (miscellaneous) 2023 Q1 Chemical Engineering (miscellaneous) 2023 Q1 9.1 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Paseta, Lorena (orcid)0000-0003-2006-1495 Echaide-Górriz, Carlos (orcid)0000-0002-0699-1293 Malankowska, Magdalena (orcid)0000-0001-9595-0831 Luque-Alled, José M.
