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.

正渗透（FO）在膜工艺中起着越来越重要的作用，因为它与传统的压力驱动膜工艺相比具有优势。有不同类型的水选择性FO膜。在这项研究中，仿生的中空纤维模块包括具有集成水通道蛋白的聚酰胺薄膜复合材料（TFC）的活性层，有效面积为0.6 m ²用于研究对24种新出现的污染物（CEC）的排斥。对所有研究的污染物获得的拒收率均高于93％，其中有19种的拒收率高达99％。观察到，尽管所有测试的化合物都显示出非常接近100％的截留率，但它们并未在进料溶液中完全回收，这使得膜内的保留成为要考虑的重要因素。因此，在每次膜操作之后必须进行两次膜冲洗才能完全回收每种污染物。考虑污染物的理化性质（分子量，电荷和疏水性）对结果进行了分析。
