“…The results showed that all membranes roughness parameters with the addition of clay were larger than those of the pure PES membrane. Similar results were also reported by different authors [25][26][27][28][29]. By adding the hydrophilic nanoparticles to the casting solution, it was observed that the mixed matrix membranes had high surface roughness in comparison to the pure membranes.…”

Membranes have been widely used in the treatment of industrial effluents. However, there are still some limitations in the separation and permeability with respect to these effluents. Therefore, this study investigated the addition of 1% and 5% of an inorganic filler (clay) in polyethersulfone polymer membranes. By contact angle analysis, it was observed that the clay influenced the hydrophilicity of the membrane. The presence of the clay had an important role in the morphology of the membrane, modifying and favoring a greater quantity of pores and macropores for the porous support. For the tensile test, it was seen that the high clay content decreased the membranes properties. The flow tests, having a flow stabilized around 300 L/h·m 2 for membranes containing clay, evidenced the efficiency of the membrane for the treatment of indigo blue, representing a 200% increase in relation to polyethersulfone membrane. The membrane containing 1% of clay presented the highest level of rejection to the effluent, around 94.0%. Thus, it was evident that the addition of montmorillonite clay modified the membrane structure contributing to a higher selectivity and permeability.

“…The FRR and RFR values after filtration of 2 mg/mL of BSA solution at pH 7.2 at different applied pressure of the membranes are presented in Figure (a,b). Generally, a high value of FRR and low value of RFR indicates a strong fouling resistance to membrane . According to Figure (a,b), it was found that the membranes with SCER displayed better antifouling properties than controlled membrane with respect to average PWF before and after BSA filtration.…”

“…The obtained results as shown in Table , clearly indicate that the surface roughness of the fabricated membrane increase with increase in SCER content. It has been reported that membranes with lower surface roughness have stronger antifouling abilities . The fouling capability tends to increase with increase in surface roughness due to accumulation of solute in the node of the rough membrane surface .…”

“…Generally, a high value of FRR and low value of RFR indicates a strong fouling resistance to membrane. 46 According to Figure 7(a,b), it was found that the membranes with SCER displayed better antifouling properties than controlled membrane with respect to average PWF before and after BSA filtration. It is interesting to note that P3 membrane shows the highest FRR (88.64%, 92.54%, and 95%) and lowest RFR (17.76%, 18.95%, and 28.99%) at pressure 3, 5, and 7 bar, respectively, among all other prepared membrane, signifying an enhanced antifouling capability of the modified membrane.…”

In this study, antifouling membranes were prepared through dry wet‐phase inversion method. The incorporation of electrostatistically charged group of sulfonate cation exchange resins (SCER) into polyethersulfone membrane matrix attempts to give a synergistic combination of properties for bovine serum albumin (BSA) removal. The effect of different composition of SCER into the blend membranes were characterized using scanning electron microscopy, atomic force microscopy, porosimeter, attenuated total reflectance Fourier transform infrared spectroscopy, and goniometer. All the prepared membranes were evaluated for BSA separation. The membrane resistance of all membranes decreases with increase in SCER loading. Among all membranes, P3 membrane shows a better fouling, reversible and irreversible resistance for BSA, signifying that the attached BSA on the membrane surface can be easily removed by physical cleaning. The improvement in hydrophilicity of P3 membrane was found to be the dominant factor in mitigating BSA fouling. The results demonstrated that BSA fouling could be alleviated by varying SCER concentration in the polyethersulfone matrix. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 45854.
