“…In addition, the permeation-rejection property was also incremented. Therefore, it was established that the grafting process indorsed the PSU film modification to obtain PSU-VIM membranes 50% ( v/v ), with the highest capacity for salt rejection and permeability, due to their hydrophilicity properties [ 72 , 73 ].…”

Polysulfone (PSU) film and N-vinylimidazole (VIM) were used to obtain grafted membranes with high hydrophilic capacity. The grafting process was performed by gamma irradiation under two experiments: (1) different irradiation doses (100–400 kGy) and VIM 50% solution; (2) different concentration of grafted VIM (30–70%) and 300 kGy of irradiation dose. Characteristics of the grafted membranes were determined by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), contact angle, swelling degree, desalination test, thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Both experiments indicated that the absorbed dose 300 kGy and the VIM concentration, at 50% v/v, were effective to obtain PSU grafted membranes with 14.3% of grafting yield. Nevertheless, experimental conditions, 400 kGy, VIM 50% and 300 kGy, VIM 60–70% promoted possible membrane degradation and VIM homopolymerization on the membrane surface, which was observed by SEM images; meanwhile, 100–200 kGy and VIM 30–50% produced minimal grafting (2 ± 0.5%). Hydrophilic surface of the grafted PSU membranes by 300 kGy and VIM 50% v/v were corroborated by the water contact angle, swelling degree and desalination test, showing a decrease from 90.7° ± 0.3 (PSU film) to 64.3° ± 0.5; an increment of swelling degree of 25 ± 1%, and a rejection-permeation capacity of 75 ± 2%. In addition, the thermal behavior of grafted PSU membranes registered an increment in the degradation of 20%, due to the presence of VIM. However, the normal temperature of the membrane operation did not affect this result; meanwhile, the glass transition temperature (Tg) of the grafted PSU membrane was found at 185.4 ± 0.5 °C, which indicated an increment of 15 ± 1%.

“…Some particles pass through the membrane, while others are retained on its surface. [ 82 ] These membrane separation techniques find application in diverse fields and can be classified based on both the driving force involved and the underlying separation mechanism. Table 1 lists the different membrane separation methods and their applications.…”

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.

In recent years, rapid development in the industrial sector has offered console to the people but at the same time, generates numerous amounts of effluent composed of toxic elements like nitrogen, phosphorus, hydrocarbons, and heavy metals that influences the environment and mankind hazardously. While the technological advancements are made in industrial effluent treatment, there arising stretch in the techniques directing on hybrid system that are effective in resource recovery from effluent in an economical, less time consuming and viable manner. The key objective of this article is to study, propose and deliberate the process and products obtained from different industries and the quantity of effluents produced, and the most advanced and ultra-modern theoretical and scientific improvements in treatment methods to remove those dissolved matter and toxic substances and also the challenges and perspectives in these developments. The findings of this review appraise new eco-friendly technologies, provide intuition into the efficiency in contaminants removal and aids in interpreting degradation mechanism of toxic elements by various treatment assemblages.
