Nanofiltration (NF) membranes are known for their higher permeance compared to reverse osmosis membranes and their capability to remove most impurities from water. However, they remain susceptible to fouling. This study aimed to develop a modification method for commercial NF membranes to achieve even higher permeance and reduced fouling propensity. The method involves ethanol-water-NaOH (EWN) activation, followed by graphene oxide (GO) coating through an amide coupling reaction. The two-step modification of a commercial NF membrane (NF270) using EWN and GO, referred to as the GO/EWN/NF270 membrane, resulted in a water permeance of 19 L/m2hbar, which is 31 % higher than that of the NF270 membrane, while maintaining a Na2SO4 rejection rate of over 96 %. Fouling tests conducted at constant transmembrane pressure (TMP) with similar initial permeate flux (40 L/m2h) using sodium alginate and real municipal wastewater showed that GO grafting significantly reduced flux decline, while EWN activation primarily enhanced intrinsic permeance and lowered the required operating TMP. Overall, the two-step strategy improves the permeability-fouling balance of the commercial NF membranes using an immersion-based process compatible with practical implementation. |
