Summary: Water is essential for life, especially in terms of drinking water. This research paper provides a comprehensive review of membrane filtration technology for treating drinking water. It focuses on membrane fouling, identifies parameters that influence fouling, and discusses various methods to handle fouling, including prevention, prediction, and control automation. The study shows that prevention is the most common treatment for fouling, although it involves the use of chemicals that may affect human health. Prediction is often used to anticipate fouling development. There is limited research on membrane fouling control based on automation, and treatment methods and control strategies are usually determined individually.

Summary: This study investigated the use of loose NF membranes for treating high turbidity and organic matter content in sand filtration effluent. The results showed high rejection of organic matter but severe membrane fouling, mainly dominated by organic fouling and inorganic fouling caused by aluminum-bearing substances. Alkaline cleaning was ineffective in removing foulants, but EDTA under alkaline conditions successfully restored membrane permeance.

Summary: Residual aluminum, specifically in the form of Ala-NOM complexes, is a significant contributor to nanofiltration membrane fouling in drinking water treatment. Increasing the concentration of both residual aluminum and coexisting natural organic matter aggravates membrane fouling. Residual aluminum produced from polyaluminum chloride has a higher membrane fouling potential compared to that produced from aluminum chloride.

Summary: Nanoplastics have become a significant environmental concern due to their adverse effects on water environments. Wastewater treatment plants are identified as major sources of nanoparticle generation, primarily through the mechanism of cracking larger plastic debris. Current membrane processes are ineffective for nanoparticle removal, leading to the need for developing a bio-nanofiltration process as an alternative method. This process can produce nanoparticle-free water for safe discharge.

Summary: This study presents a new strategy for highly efficient treatment of both synthetic and real oily emulsions using inexpensive whisker-constructed ceramic membranes. These membranes show exceptional permeance, low energy input, and better oleophobicity in water. The study explores different operating parameters and uses classical Hermia models to understand the fouling mechanism between emulsion droplets and the membrane interface. The membranes also perform well in treating real acidic oily wastewater, outperforming most state-of-the-art ceramic membranes. This work introduces a new structure concept for highly permeable whisker-constructed porous ceramic membranes that can enable more efficient water separation applications.

Summary: Membrane distillation (MD) has shown effectiveness in treating hypersaline feeds by nearly completely rejecting dissolved solutes, making it a potential treatment option for hypersaline oilfield produced water (PW). However, concerns regarding membrane fouling due to low surface energy organics in PW have been raised, with various mitigation approaches showing promise but requiring further research. In comparison to other conventional treatment options, MD offers cost-effective alternatives for beneficial re-use of PW, but efforts are still needed to improve energy efficiency and explore alternative energy sources.

Summary: This paper reviews the impact of silver on bacterial disinfection in ceramic water filters, as well as the effects of different silver application methods on silver release and retention. Research findings suggest that eluted silver contributes to bacterial disinfection in filters, but further study is needed on the prevention of a slime layer. The study also demonstrates that co-firing results in more consistent elution over time, albeit at lower concentrations compared to other methods.

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.

Summary: A transmembrane electro-chemisorption system with authigenic acid and base was developed for enhancing ammonia recovery from strong ammonia wastewater. The system efficiently transformed ammonium into free ammonia, which was then adsorbed and recovered through transmembrane chemisorption. This system yielded pure (NH4)2SO4 product and produced valuable byproducts of pure hydrogen and oxygen. Higher applied voltage resulted in better ammonia recovery.

Summary: To meet the huge demand for lithium resources, there is an urgent need to develop a new efficient technology for lithium recovery from salt-lake brines. In this study, a selective membrane capacitive deionization system is reported, which achieves high lithium recovery capacity and rate through the use of materials with efficient intercalated pseudo-capacitance and a high specific area porous carbon. The use of a modified thin-coated membrane allows for selective Li+ recovery, and adjusting the concentrations of Li+ and Mg2+ in the feed solution enables higher Li+/Mg2+ selectivity.
