“…The air resistance in the composite process is derived from the resistance of the membrane and the substrate (determined by its own structural parameters), the layer–layer resistance generated after stacking, the resistance of the gridded fiber, and the resistance generated during the membrane pore blocking (determined by the composite parameters). According to Darcy’s law, the calculation model of the resistance in the composite process is established as shown in eqs –. R normalt = R normalm + R normals + R normala + R normalb + R normalc R normali = normalΔ P normali J normali · μ R normalt = normalΔ P normalm J normalm · μ + normalΔ P normals J normals · μ + normalΔ P normala J normala · μ + normalΔ P normalb J normalb · μ + normalΔ P normalc …”

In this work, a high-gas-permeance expanded polytetrafluoroethylene/gridded fibers/polyphenylene sulfide (ePTFE/GF/PPS) filter was developed by embedding the gridded fibers as the interlayer to restrict the melting diffusion behavior of poly(phenylene sulfide) (PPS). The influence of gridded fibers with different melting temperatures on the air permeance, composite fastness, and heat tolerance was investigated. The results show that copolyamide (PA) gridded fiber with low melting temperature can weaken the effect of PPS melting so as to increase the air permeance of the ePTFE/PPS filter by 32%, which is suitable for low-temperature environments below 160 °C. The ePTFE/PAN/PPS membrane had an 8% increase in air permeance while maintaining the overall performance stable, with a heat tolerance of 200 °C. Poly(vinyl alcohol) (PVA) with a melting temperature close to that of PPS as the interlayer exhibited enhanced fastness as a compensation for the lower air permeance because of co-melting. All of the filters showed filtration efficiencies of above 99.99% and filtration resistances below 210 Pa in the particulate matter (PM) filtration experiment. The successful introduction of the gridded fiber as the intermediate layer provides a new perspective to design a composite filter with high gas permeance.

“…A pressure-driven process is commonly used to separate dye wastewater. There are four classes of pressure-driven processes, which are microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO) [72], [73]. MF possess larger pore size around 0.1 to 10 µm thus the membrane is not suitable to be used for dye wastewater treatment.…”

Methylene blue (MB) is frequently used in the textile, rubber, plastics, leather, pharmaceutical, cosmetic, and food industries. As a colouring and staining agent, MB is reported as one of the most studied dyes involving degradation and photocatalytic activity. Unfortunately, the discharge of waste from the mentioned industries contains residues of dyes, whereby the presence of a very low concentration of dyes can be highly visible. Discharging the waste without suitable treatment can cause many complications for the environment and human health. Due to that reason, the control of dye wastewater has become the most challenging task. Therefore, this review article will be focused on the MB treatment process, especially membrane filtration technology involving a pressure-driven membrane process, which is reported to be the most efficient method to treat MB dye wastewater.

“…In the past, membranes were pretreated with chlorine for efficient disinfection; however, chlorine and their derivatives often cause membrane degradation and produce harmful byproducts ( Yu et al., 2014 ). Recently, many reports have demonstrated that incorporation of metal/metal oxide/metal sulfide, carbon-based nanomaterial into the membrane is an effective strategy to circumvent the issues related to biofouling of membrane, thereby restoring the enhanced the separation performance in terms of rejection and stability ( Azhar et al., 2021 ; Liu et al., 2017 ; Nain et al., 2020b ; Rajakumaran et al., 2020 ; Zhao et al., 2021 ).…”
