Summary: The synthesized Cu-THQ MOF showed structural stability and enhanced hydrophilicity when incorporated into polyamide layers, leading to TFN membranes that broke the permeability-selectivity tradeoff by increasing water permeance and slightly enhancing salt rejection. Through different chemical and morphological characterizations, the underlying mechanism was probed, and the membranes also demonstrated improved tolerance to chlorine oxidation. With their excellent stability, the Cu-THQ MOF-based membranes further showed impressive performance in organic solvent nanofiltration involving dimethylformamide.

Summary: Reverse osmosis (RO) is a widely used desalination technology known for its high performance and reliability. Applying variable renewable energy sources (VRES) to power RO systems is an interesting option due to the energy-intensive nature of the technology. This study evaluates the performance of a seawater RO (SWRO) system with an energy recovery device (ERD) under widely variable operating conditions using an artificial neural network (ANN) model. The results show that significant energy savings and increased permeate production can be achieved, and the proposed ANN-based model accurately predicts the system's performance.

Summary: Organic micropollutants (OMPs) in drinking water pose a potential risk to human health, and their effective removal is necessary. This review discusses the application of nanofiltration (NF) and reverse osmosis (RO) membrane technologies for OMP removal. It presents a classification of OMPs based on their properties and characteristics, allowing for the study and prediction of their rejection. The review also explores rejection mechanisms and interfacial phenomena, proposing an extended Nernst-Plank equation for calculating solute transport across membranes. Ultimately, the review aims to improve predictions of OMP rejection by membranes.

Summary: Thin film composite (TFC) polyamide (PA) nanofiltration (NF) and reverse osmosis (RO) membranes are robust technologies for water treatment and desalination, but are often ineffective for removing neutral, smaller, and polar organic micropollutants (OMPs). In-situ modification of NF and RO membranes shows promise in improving OMPs rejection without changing production process. This review analyzes the impact of reported in-situ modification strategies on water permeability, OMPs retention, and NaCl rejection, while suggesting optimal modification strategies for different OMP groups.

Summary: In this study, crosslinked polydimethylsiloxane (PDMS) composite membranes were developed for organic solvent separation. The influence of PDMS molecular weight and crosslinking on membrane properties and performance was tested, and it was found that membranes prepared with lower molecular weights of PDMS showed lower permeability and higher separation coefficient. A correlation was observed between the separation coefficient and the difference of chi parameters between alcohol/PDMS and hexane/PDMS.

Summary: Per- and polyfluoroalkyl substances (PFAS) are a class of chemicals with adverse effects on ecological and human health. This study investigated the removal mechanisms and efficiencies of PFOS and PFOA from water using two different filtration media, IFGEM and CTS. The study found that IFGEM outperformed CTS in terms of PFOA removal due to its larger rate constant, higher adsorption capacity, and larger surface area. PFOS removal was influenced by the affinity of alumina for PFOS functional groups, while PFOA removal was governed by hydrophobic and electrostatic interactions. IFGEM sustained PFAS removal for a longer period of time compared to CTS.

Summary: Previous studies have shown that vibration- or rotation-based techniques can effectively mitigate fouling during membrane filtration. However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.

Summary: Increasing temperatures worldwide pose a significant health risk, exacerbated by high humidity. Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
