“…Reactive monomers and additives used during polycondensation have been adjusted to increase membrane selectivity or permeance during the design of the selective layer. [5][6][7] The incorporation of biological proteins into the membrane selective layer is a more challenging and innovative attempt. 8,9 Aquaporins (AQPs) are a large family of water-transport proteins in cells, which exhibit unique properties including high permeabilities (as many as 3 billion water molecules per second per subunit) and superior selectivities (only allowing the passage of water while rejecting all other molecules).…”

Alumina nanoparticles were decorated with poly(acrylic acid) (PAA) as a hydrophilic polymer by thermal polymerization of acrylic acid in the presence of alumina nanoparticles. The obtained PAA-decorated alumina (PAA-d-Al) nanoparticles were embedded in the polysulfone membrane matrix via nanofiller dispersion in the casting solution. The prepared membranes were characterized by porosity and water contact angle measurements, scanning electron and atomic force microscopy, and fouling tests using whey proteins. The presence of nanoparticles had significant effects on the membrane hydrophilicity and surface softness, resulting in fouling mitigation and flux recovery enhancement compared with the virgin polysulfone membrane. Moreover, the prepared membrane embedded with 0.25 wt % of PAA-d-Al nanofillers showed a remarkable durability and reusability during the filtration tests.

“…Therefore, it has been recognized as the biggest obstacle to MBR wide application in practice. One of the approach to solve this problem, is to fabricate membranes less prone to fouling by some methods, such as blending (Moriya et al 2012), coating (Chan et al 2015), adsorption (Gong et al 2015), chemical-grafting Huang et al 2015), and radiation induced grafting (Liang et al 2011).…”

Ultrafiltration membranes were prepared from blends of poly(vinylidene fluoride) (PVDF)/cellulose acetate (CA) via phase inversion method. The effect of different coagulation bath compositions on the morphology and performance of the blend membrane prepared from casting solution of PVDF/CA with ratio of 80/20 was investigated using sewage wastewater. NaCl and ethanol were used as additives of coagulation bath. Fouling analysis was conducted with Bovine Serum Albumin solution and critical flux evaluation was performed using a lab‐scale membrane bioreactor. In terms of morphological structure, the macrovoids decreased and changed to finger‐like structure. The irreversible fouling reduced and the flux recovery ratio (FRR) of the modified membranes increased remarkably while the reversible fouling caused by deposition of foulants on the surface of the membranes increased. The maximum values of FRR and critical flux of irreversibility were reached by the membrane which was prepared in the coagulation bath containing the highest concentration of NaCl.
