“…The biomedical industry may use commercially treated CA MF membranes with antibacterial properties for venting and safeguarding medical equipment and the ventilation of operating and intensive care rooms [60]. Additionally, the CA MF membranes have been used for the separation of oil and water [61,62], whey and fruit juice filtration [33], and adsorption techniques [63].…”

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.

“…Ultrafiltration purification of natural waters from petroleum products is carried out in membrane separators operating under excessive pressure [29,30]. The membranes used, which are usually made of polymers, have pairs with dimensions of 10 -9 -10 -8 m. These membranes are shaped like hollow cylinders and assembled in special modules.…”

Recently, the amount of natural waters contaminated with petroleum products, which enter surface sources together with wastewater, has increased. Therefore, the issues of natural water purification of petroleum products are given great importance. Purification of natural waters from petroleum products is possible by sorption and ultrafiltration methods. Kazan State University of Architecture and Engineering conducted research on the purification of natural waters from petroleum products in adsorption filters using various sorbents, as well as membrane separators with ultrafiltration modules from various manufacturers. As a loading of sorption filters, it is recommended to use activated charcoal as a sorbent that is optimal in terms of price and quality of water purification. The membrane modules manufactured in Europe and the United States, have a high cleaning effect from petroleum products and a sufficiently high productivity. However, they are extremely expensive.
