“…[ 110 ] A comparative analysis reveals that membrane systems, despite offering a reduced footprint advantage, entail significantly higher capital and operational costs than traditional systems. [ 111 ] This becomes particularly relevant in urban areas with high population density, [ 112 ] where land acquisition for traditional water treatment plants is costly and time‐consuming. While compact membrane systems address this issue, their smaller footprint may not be the only cost‐saving factor, as the capital and operating costs of larger traditional systems are comparatively lower, making them more viable in developing countries.…”

Membrane technology emerges as a transformative solution for global challenges, excelling in water treatment, gas purification, and waste recycling. This comprehensive review navigates the principles, advantages, challenges, and prospects of membrane technology, emphasizing its pivotal role in addressing contemporary environmental and sustainability issues. The goal is to contribute to environmental objectives by exploring the principles, mechanisms, advantages, and limitations of membrane technology. Noteworthy features include energy efficiency, selectivity, and minimal environmental footprint, distinguishing it from conventional methods. Advances in nanomembranes, organic porous membranes, and metal‐organic frameworks‐based membranes highlight their potential for energy‐efficient contaminant removal. The review underscores the integration of renewable energy sources for eco‐friendly desalination and separation processes. The future trajectory unfolds with next‐gen nanocomposite membranes, sustainable polymers, and optimized energy consumption through electrochemical and hybrid approaches. In healthcare, membrane technology reshapes gas exchange, hemodialysis, biosensors, wound healing, and drug delivery, while in chemical industries, it streamlines organic solvent separation. Challenges like fouling, material stability, and energy efficiency are acknowledged, with the integration of artificial intelligence recognized as a progressing frontier. Despite limitations, membrane technology holds promise for sustainability and revolutionizing diverse industries.

“…To study the influence of dissolved organic matter (DOM) on ARS dye adsorption onto MCN, flower soil extract that has been used in previous works [43] was chosen as a model surrogate for DOM. A series of stock solutions with different DOC (dissolved organic carbon) content was prepared in SMW, treated using MCN, and filtered through a 0.45 µm cellulose acetate membrane.…”

The wide use of alizarin red S (ARS), a typical anthraquinone dye, has led to its continued accumulation in the aquatic environment, which causes mutagenic and carcinogenic effects on organisms. Therefore, this study focused on the removal of ARS dye by adsorption onto a magnetic chitosan core–shell network (MCN). The successful synthesis of the MCN was confirmed by ATR-FTIR, SEM, and EDX analysis. The influence of several parameters on the removal of ARS dye by the MCN revealed that the adsorption process reached equilibrium after 60 min, pH played a major role, and electrostatic interactions dominated for the ARS dye removal under acidic conditions. The adsorption data were described well by the Langmuir isotherm and a pseudo-second order kinetic model. In addition to the preferable adsorption of hydrophobic dissolved organic matter (DOM) fractions onto the MCN, the electrostatic repulsive forces between the previously adsorbed DOM onto MCN and ARS dye resulted in lower ARS dye removal. Furthermore, the MCN could easily be regenerated and reused for up to at least five cycles with more than 70% of its original efficiency. Most importantly, the spent MCN was pyrolytically converted into N-doped magnetic carbon and used as an adsorbent for various dyes, thus establishing a waste-free adsorption process.

“…Both were programmed to perform challenging dead-end oil filtration tests at conditions close to full-scale application. Mini-plant testing units were revealed to be able to investigate hollow fiber membrane performance at conditions comparable to industrial application in the lab without the need for complicated/ expensive pilot-scale systems [14]. The Poseidon system was used for the initial challenging oil filtration tests to evaluate the impact of surface modification on fouling propensity.…”

Reusing wastewater from oil-related industries is becoming increasingly important, especially in water-stressed oil-producing countries. Before oily wastewater can be discharged or reused, it must be properly treated, e.g., by membrane-based processes like ultrafiltration. A major issue of the applied membranes is their high fouling propensity. This paper reports on mitigating fouling inside ready-to-use ultrafiltration hollow-fiber modules used in a polishing step in oil/water separation. For this purpose, in-situ polyzwitterionic hydrogel coating was applied. The membrane performance was tested with oil nano-emulsions using a mini-plant system. The main factors influencing fouling were systematically investigated using statistical design of experiments.
