“…These results were in agreement with previous ndings [59]. To compare the percentage of bacterial reduction in wastewater with that of coliform bacteria reduction to 1340 CFU/ml, which represents drinking water quality by nano bers [60], we note that the rate of bacterial reduction by the utilized nano bers reached 300 CFU/ml at time 8 h.…”

This study elaborates on the important role of nano bers produced from polyacrylonitrile after reinforcement with iron nanoparticles ( -Fe2O3). The objective is to expand the applications of these bers and combine their ability to remove nickel(II) from aqueous solutions with the ability to not only remove pollutants such as total suspended solids, Total Nitrogen (TN), Total Phosphor (TP), chemical oxygen demand, and cyanide but also kill the bacteria in wastewater. The absorption results for nickel(II) following the aqueous solution treatment were obtained by an atomic absorption spectrometer type (AAs-7000) and then, a spectrometer type (Hach DR2800) managed to obtain pollutant absorption results after treating wastewater samples. The results of adsorption kinetic parameters for nickel(II) proved that the rates of increase in the maximum absorption capacity ranged from 43.27 to 133.5 and from 74.63 to 178.571 mg/g when increasing the initial concentration (10{50 mg/L) for the rst and second-order models. pH, contact time, electrical conductivity, and initial concentration represented good indicators of adsorption e ciency for nickel(II), and the high removal e ciency was 23.96% at a low initial concentration. Intensi cation of the reduction rate and TN:TP ratio appeared to be signi cant enough to increase the removal rate of the total bacteria by 90% in 8 h.

“…Electrospun nanofiber mats have huge surface area to volume ratio, high porosity, great water permeability and flexibility [17,18]. These attributes enable electrospun nanofibers to demonstrate their functionality and is widely applied in air filtration [19,20], water treatment [21,22], desalination [23,24], and adsorption [25,26].…”

Improving Performance of Electrospun Nylon 6,6 Nanofiber Membrane for Produced Water Filtration via Solvent Vapor Treatment

et al. 2019

Electrospun nanofiber membrane (NFM) has a high potential to be applied as a filter for produced water treatment due to its highly porous structure and great permeability. However, it faces fouling issues and has low mechanical properties, which reduces the performance and lifespan of the membrane. NFM has a low integrity and the fine mat easily detaches from the sheet. In this study, nylon 6,6 was selected as the polymer since it offers great hydrophilicity. In order to increase mechanical strength and separation performance of NFM, solvent vapor treatment was implemented where the vapor induces the fusion of fibers. The fabricated nylon 6,6 NFMs were treated with different exposure times of formic acid vapor. Results show that solvent vapor treatment helps to induce the fusion of overlapping fibers. The optimum exposure time for solvent vapor is 5 h to offer full retention of dispersed oil (100% of oil rejection), has 62% higher in tensile strength (1950 MPa) compared to untreated nylon 6,6 NFM (738 MPa), and has the final permeability closest to the untreated nylon 6,6 NFM (733 L/m2.h.bar). It also took more time to get fouled (220 min) compared to untreated NFM (160 min).

“…Zander and his colleagues (2016) employed polyethylene terephthalate (PET) from discarded plastic bottles to create a water filter membrane, while reducing plastic waste [9]. Some studies focus on the ability of nanofibre membranes for specific water treatment, such as oil removal [10], dyes [11], bacteria or viruses [8], or desalination [12]. The development of novel polyvinyl fluoride (PVDF) nanofibrous multilayer membrane with further lamination was investigated by other researchers in the improvement of the filtration application either for air or water filtration [10].…”

Nanofibres have gained increasing attention due to their advantages of having a high porous structure, narrow pore size and distribution, and a high specific surface area. One of the most efficient techniques for producing nanofibres is via electrospinning. Nanofibres are currently being used in various fields, including water filtration. Although nanofibres possess the ability to filter various components, the fibres generally have a low mechanical strength that can mitigate the performance over time. Therefore, in overcoming this issue, several studies have focused on improving the strength of the nanofibre membranes for a water filtration application. This review discusses the advantages and challenges of nanofibres for water filtration membranes and summarises the methods to increase the strength of the membranes, including solvent vapour, thermal treatment, and chemical crosslinking.
