“…Jose R. Aguilar Cosme et al [ 117 ] found that inorganic nanoparticles' high adsorption capacity enabled nanocomposite membranes to outperform previous pristine membranes in removing dyes, metal ions, humic substances, and more. In addition, Vantanpour et al [ 118 ] modified cellulose acetate nanofiltration membranes with zeolite imidazoline framework-8 (ZIF-8) nanoparticles for water treatment applications. The study found that the ZIF-8 nanoparticles' high surface area and adsorption capacity reduced fouling caused by organic compounds, thereby enhancing the membrane's stability and fouling resistance.…”

Effective treatment of oily wastewater, which is toxic and harmful and causes serious environmental pollution and health risks, has become an important research field. Membrane separation technology has emerged as a key area of investigation in oil–water separation research due to its high separation efficiency, low costs, and user-friendly operation. This review aims to report on the advances in the research of various types of separation membranes around emulsion permeance, separation efficiency, antifouling efficiency, and stimulus responsiveness. Meanwhile, the challenges encountered in oil–water separation membranes are examined, and potential research avenues are identified.

Cellulose acetate (CA) is a semisynthetic, biodegradable polymer. Due to its characteristics, CA has several applications, including water membranes, filament-forming matrices, biomedical nanocomposites, household tools, and photographic films. This review deals with topics related to the CA membranes, which are prepared using different techniques, such as the phase inversion technique. CA membranes are considered very important since they can be used as microfiltration membranes (MF), ultrafiltration membranes (UF), nanofiltration membranes (NF), reverse osmosis (RO) membranes, and forward osmosis (FO) membranes. Membrane fouling results from the accumulation of materials that the membrane rejects on the surface or in the membrane’s pores, lowering the membrane’s flux and rejection rates. There are various forms of CA membrane fouling, for instance, organic, inorganic, particulate fouling, and biofouling. In this review, strategies used for CA membrane antifouling are discussed and summarized into four main techniques: feed solution pretreatment, cleaning of the membrane surface, membrane surface modification, which can be applied using either nanoparticles, polymer reactions, surface grafting, or surface topography, and surface coating.

“…Nanofiltration (NF) membranes are among the most favorable strategies considering their energy consumption attributes and applicability . Regarding separation properties, the NF membranes fall between the ultrafiltration (UF) and reverse osmosis (RO) membranes. , They are often made by the interfacial polymerization (IP) method and are mainly thin-film composites (TFC). The TFC NF membrane usually comprises more than one component: a polyester nonwoven fabric, which is coated by polysulfone UF membrane asymmetric porous support, and a superthin active skin layer [piperazine-polyamide (PIP–PA)] created by the in situ IP on the support surface .…”

Nanofiltration membranes play a crucial role in various separation processes, demanding continuous advancements to improve their performance and address challenges such as fouling. In this study, we present the fabrication and characterization of a high-flux thin-film composite nanofiltration membrane (TFC NF) through the incorporation of hydrophilic boron nitride quantum dots (BNQDs) at various concentrations (0.001–0.02 wt %). The membranes were synthesized by using interfacial polymerization between piperazine and trimesoyl chloride monomers. Surface analyses, including contact angle measurements, field emission-scanning electron microscopy, and atomic force microscopy, revealed that the membranes with incorporated BNQDs exhibited a smoother, more uniform, thinner, and more hydrophilic surface. Zeta potential measurements confirmed an increase in the negative surface charge of the NF membranes containing BNQDs. The separation efficiency was evaluated through a cross-flow filtration setup, with the TFC NF membrane containing 0.01 wt % BNQDs demonstrating the highest separation efficiency: 96.56% for Na2SO4, 96.48% for MgSO4, 91.3% for MgCl2, and 51.38% for NaCl, coupled with a water flux of 150.5 L/m2 h. Furthermore, water flux was enhanced in all modified membranes, reaching a maximum of 170% of the bare membrane flux (195.5 L/m2 h) in the TFC NF membrane containing 0.02 wt % BNQDs. However, with the increased flux in the TFC NF 0.02 wt % membrane, rejection rates for Na2SO4 and NaCl decreased by 1.84 and 7.15%, respectively, compared to the TFC NF 0.01 wt % membrane. Antifouling properties were evaluated by filtration of a bovine serum albumin /NaCl solution, with all modified membranes exhibiting improved antifouling properties. The TFC NF 0.02 wt % membrane demonstrated superior antifouling performance.
