Forward osmosis (FO) has proven to be a suitable process for treatment of problematic oily wastewater, due to its relatively higher water recovery rate and lower energy requirement, as opposed to pressure-driven membrane processes. Despite the lower membrane fouling propensity during FO operation, the development of comprehensively fouling-resistant membranes is further desired in FO as a suitable oily wastewater treatment process. In this current work, reduced aliphatic polyketone (rPK)-based thin film composite (TFC) membranes were developed. Reduction conditions using NaBH₄ were tested, and the suitability of reduction was evaluated with membrane morphology, water wettability, and resistance to oil. The resultant rPK-TFC membrane, whose substrate was reduced with 0.5% (w/w) NaBH₄ for 10 min, exhibited 37.8 L m⁻² h⁻¹ water flux in PRO mode. Using a foulant solution containing 1% (v/v) soybean oil, and 100 ppm humic acid, sodium alginate, and bovine serum albumin, the resultant rPK-TFC membrane maintained an outstanding 95% average flux recovery ratio, while the pristine PK-TFC membrane achieved an average flux recovery ratio of 67%. The results indicate that reduction of aliphatic polyketone is a facile method to develop membranes with outstanding water permeability and fouling resistance.

正向渗透（FO）已被证明是处理有问题的含油废水的合适方法，这是因为与压力驱动膜方法相比，正渗透率相对较高，并且具有较高的水回收率和较低的能源需求。尽管在FO操作过程中膜的结垢倾向较低，但在FO中仍需要开发一种全面的抗结垢膜，作为一种合适的含油废水处理工艺。在当前的工作中，开发了基于还原性脂族聚酮（rPK）的薄膜复合材料（TFC）膜。测试了使用NaBH _4的还原条件，并通过膜形态，水润湿性和耐油性评估了还原的适用性。所得的rPK-TFC膜，其底物被0.5％（w / w）的NaBH ₄还原在PRO模式下持续10分钟，表现出37.8 L m ^-2  h ^-1的水通量。使用含有1％（v / v）豆油，100 ppm腐殖酸，海藻酸钠和牛血清白蛋白的污垢溶液，所得rPK-TFC膜可保持出色的95％平均通量回收率，而原始PK-TFC TFC膜的平均通量回收率为67％。结果表明，脂肪族聚酮的还原是一种易于开发的膜的方法，该膜具有优异的透水性和耐污性。
