A new hyper-cross-linked polyamide TFC NF membrane (M-I) was fabricated by using tetraethylenepentamine (TEPA) and terephthaloyl chloride (TPC). Fabricated membrane M-I was treated with 15 % hydrofluoric acid (HF) and membrane was regarded as M-2. Both membranes were thoroughly characterized by FESEM, ATR-FTIR, EDX analysis, Elemental mapping, and water contact angle (WCA). Performance of both membranes was evaluated in the form of permeate flux and rejection of Eriochrome Black T (EBT) along with salts (Na₂SO₄, MgSO₄, MgCl₂, NaCl and CaCl₂) while anti-organic and antibiofouling performance of both of the membranes was studied by using Bovine Serum Albumin (BSA) as a model foulant while Escherichia coli and Staphylococcus aureus as model gram-negative and gram-positive bacterial strains. The membrane M-II showed better performance compared to the membrane M-I. The membrane M-II showed a permeate flux of 88.57 LMH at 24 bar with rejection of > 99 % of EBT and > 81 % of NaCl. The membrane M-II showed a decline in flux of merely 2.7 % with a flux recovery of 98.6 %. The bacteriostatic experiments demonstrated that the membrane M-II inhibited E. coli and S. aureus growth by 22.8 % and 77.5 %, respectively, after 24 h of incubation.

采用四亚乙基五胺(TEPA) 和对苯二甲酰氯 (TPC)制备了一种新型超交联聚酰胺TFC NF 膜(MI)。制造的膜 MI 用 15% 氢氟酸 (HF) 处理，膜被视为 M-2。两种膜都通过FESEM 、ATR-FTIR、EDX 分析、元素映射和水接触角 (WCA) 进行了全面表征。两种膜的性能都以渗透通量和 Eriochrome Black T (EBT) 以及盐（Na ₂ SO ₄、MgSO ₄、MgCl ₂、NaCl 和 CaCl _{2 ）的截留率的形式进行评估})，而通过使用牛血清白蛋白 (BSA) 作为模型污垢，而大肠杆菌和金黄色葡萄球菌作为革兰氏阴性和革兰氏阳性细菌菌株的模型，研究了两种膜的抗有机和抗生物污染性能。与膜 MI 相比，膜 M-II 表现出更好的性能。膜 M-II 在 24 bar 下显示出 88.57 LMH 的渗透通量，并具有 > 99 % 的 EBT 和 > 81 % 的 NaCl 的截留率。膜 M-II 显示通量仅下降 2.7%，通量恢复率为 98.6%。抑菌实验表明，M-II 膜在孵育 24 小时后分别抑制了 22.8% 和 77.5% 的大肠杆菌和金黄色葡萄球菌生长。
