Summary: The Millennium Development Goals (MDGs) were a crucial foundation for the Sustainable Development Goals (SDGs). A comprehensive review of 316 articles published between 2009 and 2018 identifies six factors that facilitated or impeded MDG implementation. The analysis highlights the significance of path dependencies and demonstrates that MDGs only brought about changes in countries with sufficient resources, administrative capacity, economic development, and external donor support. National ownership and NGO pressure strengthened MDG implementation efforts, indicating that globally agreed goals do not easily trickle down to the national level. This article provides forward-looking insights and lessons for the current implementation of the SDGs in developing countries.

Summary: This manuscript discusses the pilot testing of ultrafiltration (UF) membranes for drinking water supply in Spain, and the potential extension of the results to the islands of the Macaronesia area. The project aims to refurbish an existing installation at a higher altitude, which would enable the supply of drinking water to most of the island without additional pumping. The results show that UF membranes can successfully produce high-quality filtrate, making it a viable option for water treatment systems on islands.

Summary: This study used non-invasive low field magnetic resonance imaging (MRI) technology to monitor the changes in fiber-by-fiber hydrodynamics caused by fouling in a multi-fiber hollow fiber membrane module. It was shown that fouling evolution in these modules exhibited distinct trends in fiber-by-fiber volumetric flow, with increasing fouling leading to a decrease in the number of flow active fibers. The study also revealed a fouling memory-like effect, with residual fouling occurring preferentially at the outer edge of the fiber bundle during repeated fouling-cleaning cycles. MRI velocity imaging was found to be able to quantitatively monitor these effects, which are important for testing cleaning protocols and the long term operation of membrane modules.

Summary: This study systematically reports the variation in the cake layer 3D structure induced by key water quality factors and reveals its influence on water transport. Ca2+ plays a more significant role in determining cake layer structures compared to pH and Na+. The isotropic cake layer, induced by the presence of Ca2+, has higher fractions of free volume and more water channels, leading to improved water transport efficiency.

Summary: The study evaluated the removal efficiency of pathogenic microorganisms like viruses during drinking water production using ultrafiltration. Results showed that the removal rate of viruses varied depending on the concentration, with potential overestimation at high concentrations during laboratory experiments. Comparison between Evian water and real groundwater revealed similar or slightly higher virus removal rates with groundwater. Membrane ageing after chlorine exposure was found to increase water permeability but did not affect virus removal at low feed concentrations.

Summary: Radioactive liquid wastes produced at hospitals are usually temporarily stored for decay before discharge into sewage, but sometimes other hazards such as chemical or biological risks may require special treatment before discharge. Radioimmunoassay (RIA) wastes, a technique for detecting low concentrations of human substances, also require appropriate treatment before discharge after radioactive processing.

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: 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.
