“…Moreover, novel separators for LSBs with highly uniform pores or hierarchically porous structures have also been fabricated via templating methods, 364,365 anodic oxidation, 366 and advanced polymerization techniques. 367 While such fabrication techniques are popular and well-published for membranes used in nanofiltration and wastewater treatment, 368 these techniques may be tested for LSB separators.…”

“…Researchers have proved that the biofouling of the membranes can be reduced by the carbon or GO or quantum dot-based membranes as they exhibit oxidative stress on the metabolic activities of the bacteria and destruct their cell wall. Along with this, the inclusion of NPs induces hydrophilicity to the membranes and provides surface charge, improved water permeability, and biofilm antiadhesion …”

“…Along with this, the inclusion of NPs induces hydrophilicity to the membranes and provides surface charge, improved water permeability, and biofilm antiadhesion. 125 CA nanofibrous coating on PTFE substrate gave the required hydrophilicity to the hydrophobic substrate layer, and upon the addition of Si NPs, the authors were able to study oil fouling up to 30 h. An interaction between hydroxyl groups of CA and Si NPs with water molecules provides a hydration layer that prevents oil from adhering to the membrane surface. 126 N-Halamine and poly(vinyl alcohol-co-ethylene) (PVA-co-PE) NFs, with the property of chlorination, were able to kill bacteria up to 99.99% with a direct contact.…”

Despite the advantages of high contaminant removal, operational flexibility, and technical advancements offered, the undesirable fouling property of membranes limits their durability, thus posing restrictions on their usage. An enormous struggle is underway to conquer this major challenge. Most of the earlier reviews include the basic concepts of fouling and antifouling, with respect to particular separation processes such as ultrafiltration, nanofiltration, reverse osmosis and membrane bioreactors, graphene-based membranes, zwitterionic membranes, and so on. As per our knowledge, the importance of nanofiber membranes in challenging the fouling process has not been included in any record to date. Nanofibers with the ability to be embedded in any medium with a high surface to volume ratio play a key role in mitigating the fouling of membranes, and it is important for these studies to be critically analyzed and reported. Our Review hence intends to focus on nanofiber membranes developed with enhanced antifouling and biofouling properties with a brief introduction on fabrication processes and surface and chemical modifications. A summary on surface modifications of preformed nanofibers is given along with different nanofiller combinations used and blend fabrication with efficacy in wastewater treatment and antifouling abilities. In addition, future prospects and advancements are discussed.

“…It is the undesirable accumulation of marine organisms through the settlement of micro and macro-organisms on favourable surfaces, often resulting from the deposition of organic matter. Prolonged exposure to water initiates the formation of biofilms on susceptible surfaces via a continuous process of surface conditioning and recruitment in which the conditioned surface is colonised by microfoulers followed by soft and hard macrofouling, respectively (Bekiari et al, 2015; Ferreira-Vançato et al, 2020; Kim et al, 2021; Menchaca et al, 2014). The intensity and variety of the fouling community are governed by several factors such as substratum, locality, season, climate, immersion period, competition, and predation (Callow and Callow, 2002), ensuring the development of the macrofouling community as a highly dynamic and complex process.…”

Sri Lanka occupies a strategic position in the Indian Ocean, making the surrounding ocean one of the busiest in the region. The lack of fundamental studies has created a void regarding the physical and chemical behaviour of the fouling community. A few studies have been conducted to assess the subtidal biofouling communities and invasive threats in key ports and surrounding coastal waters. This study explores the chemical diversity and environmental resilience of nine marine macrofouling organisms through secondary metabolite-induced impacts on biofilm formation and volatile component analysis. The anti-settlement assay revealed that Schizoporella errata, Botrylloides violaceus, Callyspongia diffusa, and Acanthella cavernosa showed significant resistance against Escherichia coli settlement within the first 12 h (OD600 < 0.1). The identification of known compounds with a higher degree of antimicrobial activity, such as dodecanoic acid, methyl palmitate, β-caryophyllene and β-asarone, further supports the findings of anti-settlement activity of macrofouling organisms and likely plays a role in environmental resilience. KEY WORDS: Sri Lanka, anti-settlement, Escherichia coli, macrofouling, biofilm.
