2010), PES membranes were modified by inserting different concentrations of nanosized alumina (48 nm) particles inside the polymer matrix. The increase in porosity and decrease in the hydrophobic interaction between membrane surface and foulants changed the performance of the PES membrane after adding Al2O3 nanoparticles into the casting solution. , 2009). 7 Iron oxide nanoparticles Magnetic nanoparticles have gained much attention by researchers in recent years. Because of their inherent super paramagnetic properties, magnetic nanoparticles have been studied for various applications including drug and gene targeting, cell separation, and hyperthermia (Ye, Liu, Wang, Huang, & Xu, 2009).

Vatanpour et al. (2011) fabricated nanocomposite membranes composed of PES and acid-treated functionalized MWCNTs using a solution of 3 M HNO3/H2SO4 (1/3, v/v). Functionalized MWCNTs were embedded in PES matrix using the phase 12 Advances in Membrane Technologies for Water Treatment inversion method. The treated MWCNTs exhibited good dispersion and compatibility with the polymer matrix. The blending of MWCNTs into PES matrix resulted in an increase in hydrophilicity and water flux along with a decrease in fouling of the nanocomposite membrane caused by Bovine Serum Albomin (BSA) filtration.

As the result of interfacial polymerization reaction, a dense, highly cross-linked polymer layer is formed on the surface of the membrane at the interface of two solutions. Heat, ultraviolet (UV), and plasma treatment are often applied to control and complete interfacial polymerization. 1 mm or less), so TFC membrane permeability is high. Also, membrane selectivity is high as a result of the high cross-linking of polymers. Commonly used reactive monomers are aliphatic/aromatic diamines such as piperazine (PIP), m-phenylenediamine (MPDA), and p-phenylenediamine (PPD), and acid chloride monomers such as trimesoyl chloride (TMC), isophthaloyl chloride (IPC), and 5-isocyanatoisophthaloyl chloride (ICIC).
