Summary: The fouling of seawater reverse osmosis membranes is a persistent challenge in desalination. This study monitored the operational performance of a desalination plant for 7 years and the fouling development in different areas of membrane modules. The findings showed that operational performance declined over time and fouling mainly occurred at the feed side of the modules, with the highest microbial diversity. Keystone species like Chloroflexi and Planctomycetes played an important role in maintaining community structure and biofilm maturation. Polysaccharides, soluble microbial products, marine humic acid-like substances, and inorganic substances contributed to fouling. Overall, biofouling had a significant impact on membrane fouling after 7 years of operation.

Summary: Tuning the permeation properties of TFN membranes through molecular redesign is important for RO desalination performance above the trade-off limit. Activation by organic solvents can boost water permeability but has rejection loss constraints. This study innovatively integrated soluble organic macrocyclic cavitands in the activating solvent to form cavity-bearing nanocomposite structures, which improved water permeability and salt/boron rejection.

Summary: Polysilsesquioxane (PSQ) reverse osmosis membranes were prepared by copolymerizing 3-glycidyloxypropyl-POSS (GPOSS) and bis[3-(triethoxysilyl)propyl]amine (BTESPA), exhibiting high NaCl rejection, good heat resistance, and chlorine resistance. The introduction of GPOSS-derived units significantly improved NaCl rejection and liquid permeability, achieving NaCl rejection of approximately 99% and liquid permeability of 5.5 x 10-13 m/s center dot Pa. These PSQ membranes with GPOSS-derived units showed excellent heat resistance up to 100 degrees C and favorable resistance to chlorine, with no obvious performance change observed after exposure to NaOCl aqueous solution (1000 ppm) for 10 h.

Summary: Almost one billion people live in regions where water is scarce all over the world. It is estimated that by 2035, almost 3.5 billion people will be experiencing water scarcity. Membrane based technologies have been a popular choice in separation processes due to their advantages. In recent years, research in membrane technology has seen significant developments, especially in reducing energy footprints and cost. One such development is the use of nanoparticles in thin film composite membranes, known as Thin Film Nanocomposite Membranes (TFN). This review discusses the development, characteristics, advantages, and applications of TFN technology since its introduction in 2007 by Hoek.

Summary: Substrate hydrophilicity has significant impacts on the structure and performance of thin-film composite nanofiltration and reverse osmosis polyamide membranes. This study investigates the interfacial polymerization reactions on substrates with different hydrophilicity and finds that hydrophobic substrates improve the water permeance and salt rejection of RO membranes, while hydrophilic substrates enhance the performance of NF membranes. The study highlights the importance of interfacial degassing and local monomer concentration in understanding the impact of substrate hydrophilicity.

Summary: In this study, polyamide (PA) thin-film composites (TFC) with embedded silver sulfide (Ag2S) nanoparticles (NPs) were fabricated as reverse osmosis (RO) membranes to mitigate fouling. The TFN membranes were prepared by interfacial polymerization on a polysulfone support membrane. The addition of varied amounts of Ag2S NPs (20, 30, and 50 mg) in the aqueous phase resulted in membranes with enhanced antifouling and permselectivity performance. The TFN membranes exhibited high pure water flux, salt rejection, and resistance to fouling.

Summary: This study explored the feasibility of incorporating two low-energy dilution desalination processes into a conventional seawater desalination approach using real seawater and recycled wastewater. The results showed that mixing dilution of influent feed waters reduced the number of pathogenic contaminants and organic/inorganic compounds. The osmotic dilution desalination (ODD) process with the FO membrane was more effective in removing viruses and bacterial indicators compared to the mixing dilution desalination (MDD) process with the UF membrane.

Summary: Salt lake brines have become the main source of lithium due to their abundant reserves and low extraction costs. The low concentration of Li+ and the complexity of accompanying ions in the brines have inspired the development of various lithium extraction technologies. Electrodialysis (ED) has shown promising results in separating high Mg2+/Li+ ratio salt lake brines with acceptable performance, reduced energy consumption, and minimal pollution. The rapid advancement of integrated ED technologies and new strategies for membrane material fabrications have facilitated the implementation of this technology, resulting in higher energy utilization and enhanced concentration of lithium salt products. Developing membrane materials with superior permselectivity between lithium and magnesium is still a current pursuit, and coupling lithium-specific recognition materials with ED technology is believed to be the future direction for efficient and precise lithium extraction.
