Summary: Many commercial nanofiltrations (NF) and reverse osmosis (RO) membranes were evaluated for their efficiency in removing phthalates from water sources. It was found that the NF3 membrane showed the best performance in removing phthalates regardless of pH, due to its surface properties and appropriate pore size. Additionally, the NF3 membrane exhibited higher water flux compared to the RO membranes. However, further research is needed to investigate the effects of other compounds on membrane performance.

Summary: Pharmaceuticals present in water can be removed almost completely by membrane separation processes like nanofiltration and reverse osmosis. However, their adsorption onto the membranes can reduce their removal efficiency, making adsorption an important removal mechanism. Commercially available cleaning reagents including NaOH/EDTA solution and methanol were used to clean the membranes, and pure methanol was found to be the most effective in removing albendazole from the membranes, as confirmed by Fourier-transform infrared spectra.

Summary: This study assessed the usability of treated geothermal water for agricultural irrigation using membrane filtration. Different membranes were tested on laboratory and mini-pilot scales, showing variations in performance in terms of boron and arsenic removal. The permeate water produced met irrigation standards in terms of EC, TDS, and arsenic concentration, while some membranes failed to meet limits for boron and arsenic concentrations.

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: Copper (II) oxide (CuO) nanoparticles can modify water treatment membranes to enhance their adsorption properties and efficiency in handling difficult pollutants. CuO modified membranes show high rejection efficiency and can be used for solute rejection, catalytic degradation, and pollutant adsorption. However, challenges such as membrane cake formation, market penetration, and environmental concerns limit the industrial-scale application of CuO modified 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: Trace organic compounds (TOrCs) are a critical concern for water quality and safety, with advanced water treatment technologies like reverse osmosis (RO) and nanofiltration (NF) membranes showing promise in removing these compounds. The rejection mechanisms of TOrCs by RO/NF membranes remain unclear due to differences in membrane structures and limited research on TOrCs. This review focuses on characterizing rejection mechanisms and proposes future directions for improving TOrC separation performance of RO/NF membranes.

Summary: This study analyzed novel synergistic effects on rejection of arsenic and boron during membrane-based treatment. The research found that both reverse osmosis and nanofiltration membranes could meet WHO standards above pH 9 in contaminated waters, and increasing the pH from 7 to 9.5 doubled the allowable concentration of As(V) in the feed.

Summary: This study evaluated the capability of the XGBoost model in predicting micropollutant removal efficiencies of membrane separation, revealing that data leakage can lead to falsely high prediction accuracy. Utilizing a model interpretation method based on cooperative game theory, it was found that XGBoost has adequate understanding of size exclusion but limited knowledge of electrostatic interactions and adsorption.

Summary: Investigation of ion transport through artificial water channel-polyamide (AWC-PA) composite membrane revealed that the membrane provides comparable rejection and permselectivity to commercial membranes, except for bivalent cations. The study also found that strongly hydrated bivalent cations enhance the transport through AWC-PA by water clusters. Additionally, reducing the surface charge of AWC-PA membrane by adjusting pH and ionic strength decreases the rejection of anions.

Summary: In this study, polyelectrolyte complex nanofiltration membranes with lower molecular weight cut-off and lower salt rejections were prepared by electrostatic deposition method. The crosslinking steps reversed the charge property of the membrane surface and narrowed the pores of the membrane, resulting in higher rejections for both salts and organics. These results demonstrate the feasibility of using the simple electrostatic deposition method to prepare low molecular weight cut-off nanofiltration membranes for trace organic removal.

Summary: The aim of this study was to evaluate the effects of treating polyamide thin film composite membranes (PA-TFC) with n-propanol (n-PrOH) on water permeability and rejection factors for N-nitrosamines (NTRs). The results showed that exposure to n-PrOH increased water permeability by 98% for the UTC73AC membrane, while rejection factors remained relatively unchanged. For the BW30LE membrane, water permeability decreased by 38.7%, but rejection factors for NTRs increased. Furthermore, analysis of the membrane surface morphology and pore size distribution indicated that the rearrangement of polymer chains affected the network or aggregate pores in the PA layer, resulting in improved water permeability without significant impact on rejection factors for NTRs.
