Salamanca Verdugo, Mónica López Serna, Rebeca Palacio Martínez, Laura Hernández Giménez, Antonio Prádanos del Pico, Pedro Lourdes Peña Miranda, María del Mar Agripina Producción Científica Forward osmosis (FO) plays an increasingly important role in membrane processes because of its advantages compared to traditional pressure-driven membrane processes. There are different types of water-selective FO membranes. In this study, a biomimetic hollow fiber module comprising an active layer of polyamide thin film composite (TFC) with integrated aquaporin proteins and an effective area of 0.6 m2 is used to study the rejection of 24 Contaminants of Emerging Concern (CECs). The rejections obtained for all the contaminants studied were higher than 93 % and for 19 of them rejections of up to 99 % were reached. It was observed that although all the tested compounds showed rejections very close to 100 %, they were not completely recovered in the feed solution which makes the retention within the membrane an important factor to be considered. Hence, two membrane rinses were necessary after each membrane operation to completely recover each contaminant. The results were analyzed considering the physicochemical properties (molecular weight, charge and hydrophobicity) of the contaminants. 2021-10-06 2021-10-06 2021 info:eu-repo/semantics/article Journal of Water Process Engineering, 2021, vol. 40, 101914 2214-7144 https://uvadoc.uva.es/handle/10324/48933 10.1016/j.jwpe.2021.101914 eng https://www.sciencedirect.com/science/article/pii/S2214714421000015?via%3Dihub info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ © 2021 Elsevier Attribution-NonCommercial-NoDerivatives 4.0 Internacional Elsevier
