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.

“…Numerous research s tudies imply that TiO 2 -NPs alter water flux and rejection performance, as shown in Table 1 [27,[32][33][34][35]. All s tudies using the phase inversion method (NIPS) and solution cas ting to fabricate RO membranes incorporated with TiO 2 -NPs have produced different flux and salt rejection results.…”

The effect of surface coating over titanium dioxide nanoparticles (TiO2-NPs) incorporated with chitosan (TiO2-NPs/chitosan) was evaluated as a reverse osmosis membrane (RO) for enhanced performance on seawater desalination. The impact of surface coating on the chitosan membrane performance in seawater reverse osmosis (SWRO) was investigated by altering the mass of TiO2-NPs (0.25 g and 0.5 g) used for the surface coating RO membrane. TiO2-NPs were applied to the membranes using a surface coating technique and dried to create a sturdy polymer structure. The characteristic of fabricated membranes shows the function group reflects on organic compounds from /chitosan membranes polymer (–OH, -CH, C=O, C-O-C, -CH3, C-O, and NH2). In addition, TiO2-NPs are expressed in the wavenumber range of 850-500 cm-1, which characterizes the presence of Ti-O-Ti bonds. Morphological and crystal analyses of TiO2-NPs incorporated in chitosan membrane show significantly smaller pores formed because TiO2-NPs are essential in the high permeability performance under the amorphous phase structure. Also, the high performance of fabricated membranes was evaluated against water flux and salt. Adding TiO2-NPs can decrease the water flux value by 23 L m-2 h-1 and increase salt rejection by 52.94%. In optimized pH, the seawater desalination had efficient recovery.

“…4,5 Hence, the supply of freshwater using salt water desalination or wastewater treatment is very necessary and vital. Traditional freshwater production methods, such as reverse osmosis, [6][7][8] multi-stage ash distillation, 9 multi-effect distillation, 10 electrodialysis/electrodialysis reversal, 11 membrane distillation, 12,13 and capacitive deionization 14,15 are facing three key challenges: complex equipment requirements, high energy consumption, and high cost. 16,17 To address these challenges, green, and eco-friendly interfacial solar steam generation (ISSG) from seawater, brackish water, and sewage has been developed as a method to produce freshwater via photothermal evaporation using green and sustainable solar energy.…”
