Nanofiltration membranes have been widely used in many fields owing to their high separation efficiency and low energy assumption. However, traditional substrates for thin-film composite (TFC) nanofiltration membranes, such as polysulfone or polyethersulfone ultrafiltration membranes, suffer from low surface porosity and poor stability in organic solvents. A microporous polypropylene membrane (MPPM) possesses high organic solvent resistance, high porosity, but poor hydrophilicity. Herein, MPPMs were surface hydrophilized for the preparation of TFC membranes by interfacial polymerization. A green, fast, and stable deposition system based on ferulic acid and Fe3+ was employed for surface hydrophilization of MPPM, and thus, the aqueous solution of piperazine can homogeneously distribute on the substrate surface, which was directly visualized by confocal laser scanning microscopy. The nanofiltration membranes show rejection of 98.1% to Na2SO4 and water permeation flux of about 16 L/m2·h·bar. Moreover, the membranes are stable in a variety of common organic solvents, demonstrating the potential in organic solvent nanofiltration. The proposed strategy expands the selection of porous substrates for interfacial polymerization and harsh application environments for nanofiltration.

“…As it has been indicated in [20], among the most important types of NF membrane fouling are scaling, particulate and organic fouling, as well as biofouling. Importantly, biofouling represents almost 45% of the total membrane fouling [21]. It is a very complicated process, which includes the following stages [22]: (i) conditioning of the membrane surface by organic and inorganic matter occurring in the feed, (ii) microorganisms adhesion and then attachment on the membrane surface, (iii) growth of deposited cells and (iv) formation of biofilm.…”

Recent findings regarding nanofiltration (NF) have led to indications that it can be successfully used for separation of various biological solutions. As a novelty, this paper is the first to investigate the impact of the feed pretreatment process on the NF membrane performance used for separation of 1,3-propanediol (1,3-PD) fermentation broths. For this purpose, prior to the NF process, the feed was purified by microfiltration (MF) and ultrafiltration (UF) processes. Subsequently, the long-term NF process was carried out with the use of a commercial, flat-sheet, thin-film, polyamide NF270 nanofiltration membrane. Thereinto, to determine the dominant fouling mechanism, Hermia’s model was used. With regards to the pretreatment processes performed, it has been determined that the MF membrane (0.14 µm) provided the reduction in the number of bacteria cells present in the permeate, while the UF membrane (450 Da) allowed obtaining the sterile permeate. Consequently, the NF permeate flux for the UF permeate was significantly higher. Analysis of the fouling mechanisms showed that during the separation of the MF permeate, formation of a cake layer on the NF membrane surface was dominant. In turn, with regards to the UF permeate, membrane blocking occurred in two separate phases involving standard blocking and then cake layer formation. Finally, a strategy of NF membrane cleaning with the use of sodium hydroxide (NaOH) solution has been proposed.

“…Nevertheless, the recurring challenge for RO implementation is the fouling of the membranes because of the accumulation of substances on their surface. In fact, the fouling reduces the process performance and makes it necessary to resort to frequent chemical cleaning, which can accelerate the ageing of the membranes and increase the operating costs (Allaoui et al, 2022). Thus, to provide more reliable and sustainable seawater desalination technologies, the introduction of appropriate pre-treatments prior to RO remains the only effective approach to deal with the fouling phenomenon of membranes.…”

Currently, as the population continues to grow, the preservation of the world’s water resources is becoming a serious challenge. The seawater desalination process is considered a sustainable option for the future. The two most common technologies used in desalination are reverse osmosis (RO) and membrane distillation (MD). However, membrane fouling caused by the accumulation of contaminants membrane surface is an emerging and growing problem. then a pre-treatment stage is required to reach an optimal efficiency during desalination process, since this stage is crucial for a successful desalination process. In this regard, developing new material-based composite membranes has the potential to upgrade the anti-fouling features of RO membranes and thereby enhance the desalination efficiency due to the characteristics of these composite membranes especially, their high permeability, hydrophilicity, selectivity mechanical strength, thermal stability, and anti-bacterial property. The objective of this review is to present the main techniques for seawater pre-treatment. the results of several membrane types and methods of modification were also discussed. Finally, the performance of composite membranes for seawater pre-treatment is defined and future perspectives are highlighted.
