“…Hollow-fiber membranes are widely used in the osmosis processes, due to their low production costs and self-supporting capabilities. Compared with flat-sheet membranes, the hollow-fiber membranes can provide a high osmosis area-to-volume ratio, thereby obtaining high permeation fluxes from a smaller membrane area, which raises their profile for industrial applications [4,103,129].…”

Forward osmosis (FO) is an evolving membrane separation technology for water treatment and reclamation. However, FO water treatment technology is limited by factors such as concentration polarization, membrane fouling, and reverse solute flux. Therefore, it is of a great importance to prepare an efficient high-density porous membrane and to select an appropriate draw solute to reduce concentration polarization, membrane fouling, and reverse solute flux. This review aims to present a thorough evaluation of the advancement of different draw solutes and membranes with their effects on FO performance. NaCl is still widely used in a large number of studies, and several general draw solutes, such as organic-based and inorganic-based, are selected based on their osmotic pressure and water solubility. The selection criteria for reusable solutes, such as heat-recovered gaseous draw, magnetic field-recovered MNPs, and electrically or thermally-responsive hydrogel are primarily based on their industrial efficiency and energy requirements. CA membranes are resistant to chlorine degradation and are hydrophilic, while TFC/TFN exhibit a high inhibition of bio-adhesion and hydrolysis. AQPs are emerging membranes, due to proteins with complete retention capacity. Moreover, the development of the hybrid system combining FO with other energy or water treatment technologies is crucial to the sustainability of FO.

“…Various types of polymers have been used in the production of membranes for water separation applications, such as cellulose [20][21][22], cellulose derivatives [23][24][25], poly (ethersulfon) (PES) [26][27][28], poly (sulfone) (PSf) [29][30][31], and poly (vinyl chloride) (PVC) [32][33][34][35] as well as the batter. Interestingly, the rubber-based membrane had the potential to be utilized in wastewater treatment applications [36].…”

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.

“…It can be said that PVC products accompanied human life: from medical devices to furniture. [1][2][3][4] However, in order to obtain flexible materials, in most cases, PVC is usually mingled in a large number of plasticizers, up to 70 wt%, the dipole bonding between polymer chains is greatly diminished, thereby the freedom of chain movement is increased. However, these additives also undergo an exceptive combustion mechanism, which generates a large amount of smoke.…”

Doping is a simple and effective method to change material properties. In this work, in order to improve the flame retardant performance of bismuth oxychloride (BiOCl) nanosheets in poly (vinyl chloride) (PVC), for the first time, iron and tin ions were doped into BiOCl (Fe-BiOCl and Sn-BiOCl) via a doping approach, respectively. X-ray diffraction and morphology characterization confirmed that the Fe and Sn ions were doped into the BiOCl lattices, respectively. After doping, PVC composites obtained superior flame retardancy and smoke suppression. With the adding amount of 3 wt% Fe-BiOCl and Sn-BiOCl, the UL-94 test rating of the PVC composites reached V-0, and the peak of heat release rate reduced by 38% and 34%, total smoke production decreased by 55% and 42%, respectively, compared to neat PVC. Thermogravimetric and Thermogravimetric-Fourier Transform Infrared results showed that Fe or Sn doping could further reduce organic volatiles in the gasphase and improve char residual in the condensed phase, both of which contribute to reducing fire hazards. Tensile properties and tensile modulus of PVC composites increased. In short, it is an economically effective approach targeting to improve the comprehensive properties of PVC through doping Fe or Sn into BiOCl.
