“…It might give the ideal shape with greater hydrophilicity, improved fouling resistance, mechanical, chemical, and thermal stability throughout a wider pH and temperature range in addition to the physicochemical stability of one element. Polymeric membranes have grown in popularity in the water treatment sector as a result of their low manufacturing costs, ease of preparation, and flexible pore structure, as well as their excellent product quality, ease of scaling up, decreased energy consumption, and environmental friendliness [11][12][13][14].…”

This study investigated the separation of bovine serum albumin using a novel matrix mixed membrane composed of poly vinyl pyrrolidone and poly (phenylene ether ether sulfone)/Nano-silver. The responsive bare and modified PEES/Nano-silver membranes were evaluated using morphology, wettability, XRD and ATR-FTIR. The molecular weight cut-off (MWCO), water content, mean pore radius, porosity, and pure water flux were used to evaluate the presentation of mixed matrix membranes. The outcomes show that the membranes wettability is increased by the addition of PVP, which promotes the formation of hydrogen bonds. Its clear that the membranes are more hydrophilic than the PEES/Nano-silver membrane based on their performance. In addition, model foulants such bovine serum albumin (BSA) and E. coli were used to assess the efficacy of mixed matrix membranes anti-fouling properties. PVP loading results in more diversified surface morphology with asymmetric structure and higher water flux (4.35 × 10 -5 ms-1) than the pristine membrane (2.23 × 10-5 ms-1) as a reference at 3.5 bar without compromising the rejection of membrane. The flux recovery ratio for PEES/PVP/Nano-Silver membranes is 97%, which is significantly higher than the ratio for PEES/Nano-Silver membranes (62%). Furthermore, The results of fluorescence microscopy showed that, compared to clean membranes, the modified membranes have biofouling activities.

Review of New Approaches for Fouling Mitigation in Membrane Separation Processes in Water Treatment Applications

This review investigates antifouling agents used in the process of membrane separation (MS), in reverse osmosis (RO), ultrafiltration (UF), nanofiltration (NF), microfiltration (MF), membrane distillation (MD), and membrane bioreactors (MBR), and clarifies the fouling mechanism. Membrane fouling is an incomplete substance formed on the membrane surface, which will quickly reduce the permeation flux and damage the membrane. Foulant is colloidal matter: organic matter (humic acid, protein, carbohydrate, nano/microplastics), inorganic matter (clay such as potassium montmorillonite, silica salt, metal oxide, etc.), and biological matter (viruses, bacteria and microorganisms adhering to the surface of the membrane in the case of nutrients) The stability and performance of the tested nanometric membranes, as well as the mitigation of pollution assisted by electricity and the cleaning and repair of membranes, are reported. Physical, chemical, physico-chemical, and biological methods for cleaning membranes. Biologically induced biofilm dispersion effectively controls fouling. Dynamic changes in membrane foulants during long-term operation are critical to the development and implementation of fouling control methods. Membrane fouling control strategies show that improving membrane performance is not only the end goal, but new ideas and new technologies for membrane cleaning and repair need to be explored and developed in order to develop future applications.

“…The results confirm that the obtained hybrid membranes, which are more hydrophilic, as indicated by the contact angle values, can prevent the attachment of BSA molecules to the membrane surface. These can be removed by back-washing, as reported in other studies [ 41 , 42 ].…”

This study presents the preparation of hybrid nanofiltration membranes based on poly(1,4-phenylene ether ether sulfone), polyacrylonitrile, poly(vinyl pyrrolidone), and SBA-15 mesoporous silica. Laser treatment of polymeric solutions to enhance the hydrophilicity and performance of membranes was investigated. The membranes’ structure was characterized using scanning electron (SEM) and atomic force (AFM) microscopy and contact angle measurements. The addition of PAN in the casting solution produced significant changes in the membrane structure, from finger-like porous structures to sponge-like porous structures. Increased PAN concentration in the membrane composition enhanced the hydrophilicity of the membrane surface, which also accounted for the improvement in the antifouling capabilities. The permeation of apple pomace extract and the content of polyphenols and flavonoids were used to evaluate the efficacy of the hybrid membranes created. The results showed that the hybrid nanofiltration membranes based on PPEES/PAN/PVP/SBA-15: 15/5/1/1 and 17/3/1/1 exposed to laser for 5 min present a higher rejection coefficient to total polyphenols (78.6 ± 0.7% and 97.8 ± 0.9%, respectively) and flavonoids (28.7 ± 0.2% and 50.3 ± 0.4%, respectively) and are substantially better than a commercial membrane with MWCO 1000 Da or PPEES-PVP-based membrane.
