“…These factors will be the heart of our discussion in this study. Tables S1 and S2 present a set of published results on single and multiple layer/polymer ENMs for water treatment (desalination and ion removal), respectively (summarized by Sanaeepour et al [22]). Understanding the interaction between operating parameters and membrane characteristics and features is considered tedious and time consuming [23].…”

Nowadays, acquiring a water supply for urban and industrial uses is one of the greatest challenges facing humanity for ensuring sustainability. Membrane technology has been considered cost-effective, encompasses lower energy requirements, and at the same time, offers acceptable performance. Electrospun nanofibrous membranes (ENMs) are considered a novel and promising strategy for the production of membranes that could be applied in several treatment processes, especially desalination and ion removal. In this study, we apply an unsupervised machine-learning strategy, the so-called principal component analysis (PCA), for the purpose of seeking discrepancies and similarities between different ENMs. The main purpose was to investigate the influence of membrane fabrication conditions, characteristics, and process conditions in order to seek the relevance of the application of different electrospun nanofibrous membranes (ENMs). Membranes were majorly classified into single polymers/layers, from one side, and dual multiple layer ENMs, from another side. For both classes, variables related to membrane fabrication conditions were not separated from membrane characterization variables. This reveals that membranes’ characteristics not only depend on the chemical composition, but also on the fabrication conditions. On the other hand, the process conditions of ENM fabrication showed an extensive effect on membranes’ performance.

“…Electrospinning is a versatile method for making nonwoven nanofibrous membranes with a submicronic-interconnected pore-like structure that can be used in a wide range of applications at a low cost [111]. Electrospun polymer nanofibers have emerged as one of the most encouraging and evolving engineered materials for membrane synthesis due to their extremely high porosity, high permeate flux and selectivity, excellent physicochemical stability, and tunable properties [112]. Nanofibers made with this unique electrospinning process have a large surface area compared to nanofibers made with other spinning processes.…”

Natural Fiber-Reinforced Thermoplastic ENR/PVC Composites as Potential Membrane Technology in Industrial Wastewater Treatment: A Review

et al. 2022

Membrane separation processes are prevalent in industrial wastewater treatment because they are more effective than conventional methods at addressing global water issues. Consequently, the ideal membranes with high mechanical strength, thermal characteristics, flux, permeability, porosity, and solute removal capacity must be prepared to aid in the separation process for wastewater treatment. Rubber-based membranes have shown the potential for high mechanical properties in water separation processes to date. In addition, the excellent sustainable practice of natural fibers has attracted great attention from industrial players and researchers for the exploitation of polymer composite membranes to improve the balance between the environment and social and economic concerns. The incorporation of natural fiber in thermoplastic elastomer (TPE) as filler and pore former agent enhances the mechanical properties, and high separation efficiency characteristics of membrane composites are discussed. Furthermore, recent advancements in the fabrication technique of porous membranes affected the membrane’s structure, and the performance of wastewater treatment applications is reviewed.

“…To improve the fiber quality, different nanoparticles are mixed with polymers and then electrospun to produce the scaffold without a functionalization process [ 12 ]. Some studies have investigated the addition of materials, such as SiO 2 , Al 2 O 3 , CuO, and TiO 2 in electrospun fibers to improve their performance [ 6 , 13 , 14 , 15 ]. The selection of a polymer that becomes a membrane matrix is also important, as it affects membrane parameters such as surface tension, electrical conductivity, and viscosity [ 16 ].…”

Electrospun Silica-Polyacrylonitrile Nanohybrids for Water Treatments

et al. 2023

View full text Add to dashboard Cite

In this work, the removal of NOM (natural organic matter) as represented by humic acid by means of electrospun nanofiber adsorptive membranes (ENAMs) is described. Polyacrylonitrile (PAN) was used for the preparation of ENAMs incorporating silica nanoparticles as adsorbents. The addition of silica to the polymer left visible changes on the structural morphology and fibers’ properties of the membrane. The membrane samples were characterized by pure water permeability, contact angle measurement, SEM, XPS, and XRD. This study assesses the preliminary performance of PAN-Si membranes for the removal of natural organic matter (NOM). The membrane rejected the humic acid, a surrogate of NOM, from 69.57% to 87.5%.
