膜污染是阻碍反渗透（RO）应用的主要障碍之一 饮用水行业的膜技术。因此，开发膜 具有更好的抗污垢能力已成为一个日益重要的领域。在这个 在这项研究中，我们制备了五种市售抗污染低压反渗透膜 研究了高有机污染物对季节性微咸水的处理 含量（H 24 mg/L）。所研究的膜是LFC-1（液压），X20 （Trisep）、BW30FR1（FilmTec）、SG（Osmonics）和BE-FR（Saehan）。所有膜 是由聚酰胺衍生物制成的薄膜复合材料。它们的表面 膜在粗糙度、电荷和温度方面进行了彻底的表征 疏水性，使用原子力显微镜（AFM），流动电位分析 （SPA）和角度计的接触角测量。污垢 通过平板膜测试进一步评估耐腐蚀膜 使用凝结的地表水。此外，还进行了中试规模评估，以 评估长期绩效。包括5个参考文献、表格、图表。

Membrane fouling is one of the primary obstacles that have hampered the use of reverse osmosis (RO) membrane technology in the drinking water industry. Thus, developing membranes with a better resistance to fouling has become an area of increasing significance. In this study, five commercially available fouling resistant low-pressure RO membranes were investigated for the treatment of seasonally brackish surface water with high organic content (H 24 mg/L). The membranes investigated are LFC-1 (Hydranautics), X20 (Trisep), BW30FR1 (FilmTec), SG (Osmonics), and BE-FR (Saehan). All membranes were thin film composite made of polyamide derivatives. The surfaces of these membranes were thoroughly characterized in terms of roughness, charge and hydrophobicity, using Atomic Force Microscopy (AFM), Streaming Potential Analysis (SPA), and contact angle measurements by Goniometer, respectively. The fouling resistant membranes were further evaluated by performing flat-sheet membrane testing using coagulated surface water. In addition, pilot-scale evaluation was conducted to assess long-term performance. Includes 5 references, tables, figures.
