“…CA is resistant to chlorine and solvents, which makes it a suitable material for membranes [72]. For CA-NF membrane preparation, a mixture of acetone and formamide [39,43,84] or NMP [42] is utilized in the process of preparing the casting solution. First, the solution is stirred to dissolve the CA polymer.…”

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.

“…After degassing, the solution of CA is cast on a glass plate and then instantly immersed in a cold-water bath for a few hours. Following that, the membranes are submerged in a hot water bath for a few minutes so that any remaining solvent is removed [39,43,84].…”

“…Hence, it is imperative to expedite the development of an efficient and dependable water purification technology. So far, conventional physical and chemical processes, including adsorption, coagulation, oxidation, and membrane techniques, have emerged as the primary approaches and experimental methods for industrial wastewater treatment [ [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] ]. While traditional wastewater treatment methods have been shown to be effective in removing organic dyes, their effectiveness is limited when dealing with complex chemical structures.…”

Cigarette waste is a persistent environmental problem that requires innovative solutions due to the inadequacy of traditional recycling methods. This paper explores the conversion of cigarette butt filters (CBFs) into raw material for cellulose acetate (CA) membrane production. This study prepared two types of membranes: 12% CBF and 12% CA as a control variable. The resulting material was evaluated for its properties and performance as an ultrafiltration membrane for organic contaminant removal. The result demonstrates that the CBF-based membrane exhibits superior characteristics to a CA-based membrane. This improvement is evident in the increased presence of hydroxyl (-OH) groups and enhanced porosity CA 18,37% and CBF 19,66%. Furthermore, the permeability of the CBF membrane has also increased, making it an efficient tool for maintaining humic acid removal CBF 79,02% and CA 66,18% while achieving a high flux ratio recovery CA 65,25 % and CBF 87,97%. The findings in this paper emphasize the promising potential of reusing cigarette waste as an eco-friendly membrane with high humic acid rejection and good antifouling properties.
