The photocatalytic nanocomposite NF membranes blended with K-B-N triple TiO₂ were fabricated employing conventional wet phase inversion method. The dynamic performance of the photocatalytic membranes was evaluated by filtering biologically treated palm oil mill effluent (POME) at dark and light conditions. The performance of the chosen membrane was checked using central composite design (CCD) of response surface methodology (RSM) under continuous visible light irradiation and various variables in a dynamic mode. According to experimental results, the 0.5 wt. % membrane indicated less flux reduction without scarifying COD rejection capacity as a function of time while filtering POME under continuous visible light irradiation. The largest values of FRR and COD removal efficiency were reported to be 97 % and 100 %, respectively, at the highest feed flow rate of 150 L/min, the lowest operating pressure of 5 bar, and the lowest COD concentration of 1000 mg/L. While, the highest value of flux (33.9 kg/m²h) was obtained at operating pressure of 9 bar, feed flow rate of 50 L/h and COD concentration of 1000 mg/L. By judging from results, the photocatalytic NF membrane by benefiting from both photocatalytic and self-cleaning properties has enough potential to be applied in practical applications.

与KBN三重TiO ₂混合的光催化纳米复合NF膜采用传统的湿相转化方法制造。通过在黑暗和光照条件下过滤生物处理过的棕榈油厂废水 (POME) 来评估光催化膜的动态性能。在连续可见光照射和动态模式下的各种变量下，使用响应面方法 (RSM) 的中心复合设计 (CCD) 检查所选膜的性能。根据实验结果，0.5 wt. 在连续可见光照射下过滤 POME 时，% 膜表明通量减少较少，而不会破坏 COD 截留能力随时间的变化。据报道，最大的 FRR 和 COD 去除效率分别为 97% 和 100%，最高进料流速为 150 L/min，最低工作压力为 5 bar，最低COD浓度为1000 mg/L。而通量的最高值（33.9 kg/m在 9 bar 的操作压力、50 L/h 的进料流速和 1000 mg/L 的 COD 浓度下获得² h)。从结果来看，兼具光催化和自清洁特性的光催化纳滤膜具有足够的应用潜力。
