“…These membranes are classified based on their pore size as well as their molecular weight cut off (MWCO), with a separation mechanism that is based on size exclusion. However, NF membranes can show a mix of size exclusion and diffusion [ 113 ]. The addition of hydrophilic nanosheets improves membrane performance by increasing the porosity, the elongation, and the widening of microvoid fingers.…”

In this study, the characteristics of different types of nanosheet membranes were reviewed in order to determine which possessed the optimum propensity for antifouling during water purification. Despite the tremendous amount of attention that nanosheets have received in recent years, their use to render membranes that are resistant to fouling has seldom been investigated. This work is the first to summarize the abilities of nanosheet membranes to alleviate the effect of organic and inorganic foulants during water treatment. In contrast to other publications, single nanosheets, or in combination with other nanomaterials, were considered to be nanostructures. Herein, a broad range of materials beyond graphene-based nanomaterials is discussed. The types of nanohybrid membranes considered in the present work include conventional mixed matrix membranes, stacked membranes, and thin-film nanocomposite membranes. These membranes combine the benefits of both inorganic and organic materials, and their respective drawbacks are addressed herein. The antifouling strategies of nanohybrid membranes were divided into passive and active categories. Nanosheets were employed in order to induce fouling resistance via increased hydrophilicity and photocatalysis. The antifouling properties that are displayed by two-dimensional (2D) nanocomposite membranes also are examined.

Phthalate esters (phthalic acid esters or PAEs) are widely utilized during production as an inactive plasticizer, which results in serious water pollution. Ideal removal of micropollutants is difficult to achieve with traditional water treatment, but technology using nanofiltration membrane removes water micropollutants effectively owing to its unique membrane structure. To further study the rejection performance of nanofiltration membrane for PAEs, carbon nanotube-modified nanofiltration membrane was proposed to treat PAEs in water. The adsorption and rejection properties of PAEs on the surface of nanofiltration membrane were revealed by multi-factor experiments. Adsorption kinetics was also analyzed, and the adsorption isotherm of PAEs on the membrane surface was simulated. In addition, the effects of running time, molecular weight, n-octanol/water partition coefficient, and average polarizability on the performance of PAE rejection of nanofiltration membrane were discussed. Results show that the Freundlich adsorption equation simulates the adsorption of PAEs on the surface of the nanofiltration membrane, and the correlation coefficient is more than 0.998. The adsorption capacity of the nanofiltration membrane for three typical PAEs substances, namely, diethyl phthalate (DEP), dibutyl phthalate (DBP), and dioctyl phthalate (DOP), decreases in turn. At the same time, the early rejection of PAEs by nanofiltration membrane is primarily due to the adsorption of membrane surface, and the equilibrium stage depends mainly on the sieving effect of the membrane pores. This study provides a theoretical basis for the application of nanofiltration membrane in the removal of PAEs.
