Emerging insights into nanocomposite membranes for sustainable wastewater treatment technologies

Technologies for membrane-based separation processes have been extensively employed in wastewater treatment. The most often used membranes in wastewater ultrafiltration are polysulfone (PSF) membranes because of their mechanical strength, structural durability, and chemical resistance. Phase inversion and electrospinning are two of the many ways to make membranes from hydrophobic polymers like polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE), or polypropylene (PP). Several research investigations have improved the membrane's polymeric surface's ability to attract water. More recently, metal nanoparticles have been added to the polymer matrix to make it less likely to get dirty and work better. Recent advancements in nanotechnology help increase pollution removal by getting around the problems with standard treatment technologies and providing low-cost treatment solutions with great capacity. Also, changing the surfaces of membranes with a nanocomposite improves performance by creating synergistic effects between organic and inorganic parts. In this context, the addition of natural fibers like jute to nanocomposites has become popular since jute is plentiful, biodegradable, and naturally able to adsorb. When chemically altered, such as through in-situ polymerization of composites, these materials show a greater ability to remove organic and heavy metal pollutants in a series. This is a long-lasting way to recycle adsorbents and cut down on waste. The categorization of the membranes utilized in various water treatment processes is added in this review, that includes nanostructures, nanoparticles, and nanocomposites, is novel and different. The characteristics of different nanocomposites' for removing pollutants from water, wastewater, and groundwater, and their advantages and drawbacks are assessed and examined.
