Magnetic MBR technology: from the fabrication of membrane to application in wastewater treatment

Unveiling the revolutionary role of nanoparticles in the oil and gas field: Unleashing new avenues for enhanced efficiency and productivity

“…Not only that, but a tubular ultrafiltration (UF) membrane made of an Al 2 O 3 -poly (vinylidene difluoride) nanocomposite has been also reported. This membrane performed incredibly well in the treatment of oily wastewater [ 82 , 83 ]. From that results it was noted that the addition of nano-sized Al 2 O 3 particles improves membrane anti-fouling performance.…”

Morphological effects of sphericalSiO2and hexagonal mesoporousMCM‐41 nanoparticles in polyacrylonitrile mixed matrix membranes on the biofouling mitigation in short‐term filtration

“…1 As of late, polymer membranes have become widespread and common due to their applications in numerous industries, such as desalination, 2 oily wastewater treatment, 3 dairy industries, 4 dye removal, and protein separation. 5,6 Polyacrylonitrile (PAN) is the most common polymers, which can be dissolved in many polar organic solvents such as dimethyllacctamide (DMAc), dimethylformamide (DMF), and n-methyl-2-pyrrolidone (NMP), 7 and is often used for separation application due to its solvent resistance, 8 chemical stability, mechanical behavior, 9 and thermal stability. 10 Despite that, due to the hydrophobic nature of most polymeric membranes and the low surface energy of most of them, some obstacles exist like flow resistance, membrane fouling, and low filtration rates.…”

Flexible, durable, and anti-fouling maghemite copper oxide nanocomposite-based membrane with ultra-high flux and efficiency for oil-in-water emulsions separation

“…The integration of nanoparticles into membrane technology has garnered substantial attention in recent years, primarily due to their transformative potential across various applications, notably in the realm of oil–water emulsion separation (Yi et al 2013 ; Sinha Ray et al 2020 ; Nain et al 2022 ). Magnetic nanoparticles (MNPs) stand out owing to their unique physicochemical characteristics and exceptional biocompatibility, making them highly promising as additives in different types of membranes, such as polysulfone (PS), polyvinylidene fluoride (PVDF), and polyethersulfone, all widely employed for the treatment of oily wastewater (Heidi Lynn et al 2012 ; Rashdan et al 2013 ; De Sitter et al 2014 ; Homayoonfal et al 2014 ; Barroso-Solares et al 2018 ; Ramazanov et al 2020 ; Mehrnia et al 2021 ; Mirzaei et al 2021 ; Koyuncu et al 2022 ). The incorporation of MNPs into these membranes has yielded tangible benefits, particularly in terms of bolstering their antifouling properties, thereby enhancing overall performance.…”
