Cellulose Acetate Membranes: Fouling Types and Antifouling Strategies—A Brief Review

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 the which are prepared using different techniques, such as phase inversion technique. membranes considered very important since they can be used microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO) forward (FO) membranes. Membrane fouling results from accumulation of materials that membrane rejects on surface or in membrane’s pores, lowering flux rejection rates. There various forms fouling, for instance, organic, inorganic, particulate biofouling. In this review, strategies antifouling discussed summarized into four main techniques: feed solution pretreatment, cleaning surface, modification, applied either nanoparticles, polymer reactions, grafting, topography, coating.
