The raising oil consumption in oil and gas industries has exacerbated the disposal of oil waste into various water streams. This phenomenon has called for treatments to prevent threats to the human and environment. With some great advantages such as lower membrane fouling rate, lower energy requirement and higher water recovery rate compared to the conventional pressure-driven membrane processes, forward osmosis (FO) has been recognized as a potential candidate for oily wastewater treatment. In this study, a poly[3-(N-2-methacryloylxyethyl-N,N-dimethyl)-ammonatopropanesulfonate] (PMAPS) incorporated thin film composite (TFC) membrane with excellent anti-fouling properties was fabricated for oily wastewater through forward osmosis process. PMAPS was blended with polyethersulfone (PES) dope solution and cast into PES support layer. Interfacial polymerization (IP) technique was applied to form a thin polyamide (PA) layer atop of the PES support layer. The PMAPS incorporated TFC membranes were characterized for their morphology and surface hydrophilicity. The resultant 1% PMAPS-TFC membrane exhibited high water flux of 15.79 ± 0.3 L/m².h and oil flux of 12.54 ± 0.8 L/m².h when tested in FO mode for oil removal from oily wastewater using 1000 ppm emulsified oily solution as feed solution and 2 M NaCl as draw solution. The oil rejection up to 99% was also obtained. Most significantly, PMAPS incorporated TFC membrane outperformed neat TFC membrane with lower fouling propensity for oily waste treatment. When treating 10000 ppm oil emulsion, PMAPS-TFC was able to achieve average flux recovery rate of 97% while neat TFC only able to achieve 70.8% of average flux recovery rate.

石油和天然气工业中不断增长的石油消耗加剧了将废油处理成各种水流的过程。这种现象要求采取预防措施，以防止对人类和环境的威胁。与传统的压力驱动膜工艺相比，膜渗透率低，能耗低，回水率高等优点，被公认为是处理含油废水的潜在选择。在这项研究中，聚[3-（N -2-甲基丙烯酰氧乙基-N，N通过正向渗透工艺制备了含油的废水，具有优异的防污性能的薄膜复合膜（TMAP）。将PMAPS与聚醚砜（PES）涂料溶液混合，并浇铸到PES支撑层中。应用界面聚合（IP）技术在PES支撑层顶部形成薄聚酰胺（PA）层。结合了PMAPS的TFC膜的形貌和表面亲水性得到了表征。所得的1％PMAPS-TFC膜显示出15.79±0.3 L / m ² .h的高水通量和12.54±0.8 L / m ^2的油通量.h在FO模式下进行测试，使用1000 ppm乳化油溶液作为进料溶液，2 M NaCl作为汲取溶液从含油废水中去除油。还获得了高达99％的拒油率。最重要的是，PMAPS并入的TFC膜优于纯净的TFC膜，具有较低的结垢倾向，可用于处理含油废物。当处理10000 ppm油乳液时，PMAPS-TFC能够实现97％的平均通量回收率，而纯净TFC只能实现平均通量的70.8％的回收率。
