“…The roughness reduction can be relevant to the functional electrostatic interactions of N‐H groups of the SNW‐1 and the polymer chains 39,40 . Also, at the membrane fabrication step during the phase inversion, the movement of the SNW‐1 nanoparticles to the membrane surface can cause the reduction of the roughness parameters 41 . The protein fragments wish to be adsorbed on the membrane surfaces valleys, that is, the higher surface roughness of the membranes promotes the fouling phenomenon 40,42 .…”

This research reported developing a polyethersulfone (PES) membrane using covalent organic frameworks (COFs) nanoparticle with a mean dimension of 30 nm. The SNW‐1 (Schiff‐based network) COF was synthesized using precursors of melamine and terephthalic acid and then characterized by XRD, SEM, TEM, and FTIR analyses. The influence of different loadings of the COF was evaluated on the permeability, antifouling behavior and dye/salt rejection. The addition of SNW‐1 caused a reduction in surface roughness and an improvement in hydrophilicity of the nanocomposite membranes, which improved their flux and fouling resistance considerably. The improvement of water flux, 2.6 times, was observed by adding 0.5 wt% COF to the membrane matrix. The 0.5 wt% COF membrane presented the best water permeability, 38.9 L/m2 h bar BSA solution flux, dye rejection of 98.7% for Reactive Green 19 and 62.6% for Reactive yellow 39, 52.9% Na2SO4 and 24.5% NaCl salt rejections. Zeta potential and salt rejection trend indicated a negative surface charge on the nanocomposite membrane. Fouling experiments by BSA protein solution exhibited that the FRR reached 88.9% for 2 wt% COF membrane. Thus, employing SNW‐1 into PES matrix resulted in a promising nanofiltration membrane for dye separation and moderate salt separation with suitable antifouling properties.

“…Therefore, the MOFs-based modified membranes have promising industrial application prospects in the treatment of oily wastewater. [70] Yang et al synthesized GO and MOFs@GO modified composite UF membranes. The study found that the combination of HKUST-1 and GO could effectively overcome the shortcomings of GO and could make full use of the properties of GO.…”

Metal-organic frameworks (MOFs) are a new class of organic-inorganic hybrid microporous crystalline materials formed by the self-assembly of inorganic metal ions and organic ligands. Due to their high specific surface area, tunable pore structures, good thermal stability, and exceptional porosity, MOFs are introduced as novel fillers for incorporation in the polymeric matrix to form composite membranes for different applications. In this review, the synthesis methods of MOFs and the preparation methods of MOFs-based membranes are summarized, focusing on the application of MOFs-based membranes in water purification. In addition, the perspectives of MOFs-based membranes in the separation field are proposed.

“…It should be mention that an increase in the CNC-Ser loading (0.5, and 1.0 wt.%) resulted an increase in WCA and a reduction in the hydrophilicity of the membranes which could be explained by an increasing trend of the viscosity casting solution in higher loading of CNC-Ser. Moreover, the aggregation of nanostructures in higher loading could be another reason for decreasing homogeneity and increasing WCA besides the viscosity increscent (Samari, Zinadini, Zinatizadeh, Jafarzadeh, & Gholami, 2020).…”

As discharging oily wastewater from industries to the environment is a potential threat for the aquatic ecosystem, in this research oil removal from a real case of Kermanshah polymer production plant wastewater was investigated. The focus of this study was on improving the oil rejection performance of polyethersulfone (PES) ultrafiltration membrane due to adding cellulose nanocrystals (CNC) and modified CNC with Serine amino acid (CNC-Ser) in PES mix matrix. From the results, the membranes embedded with CNC-Ser showed better performance in terms of water flux, flux recovery ratio and oil rejection (higher than 97%) compared to the modified membranes with CNC. The lowest water contact angle (41.370), the smoother surface and higher negative surface potential (-24 mv) was achieved for the optimum loading of CNC-Ser. Besides, long-term performance of the membranes with optimum loading of CNC and CNC-Ser were compared in both dead-end and cross-flow set-ups.
