“…In a study, Fatima et al [90] successfully synthesized a low-cost and highly permeable NaA zeolite membrane via an in situ crystallization approach using the secondary growth method on a kaolinite support. The synthesis conditions, including temperature, time of crystallization, and water ratio, were systematically investigated to obtain the optimal membrane quality and thus performance.…”

Ethanol, a versatile chemical extensively employed in several fields, including fuel production, food and beverage, pharmaceutical and healthcare industries, and chemical manufacturing, continues to witness expanding applications. Consequently, there is an ongoing need for cost-effective and environmentally friendly purification technologies for this organic compound in both diluted (ethanol-water–) and concentrated solutions (water-ethanol–). Pervaporation (PV), as a membrane technology, has emerged as a promising solution offering significant reductions in energy and resource consumption during the production of high-purity components. This review aims to provide a panorama of the recent advancements in materials adapted into PV membranes, encompassing polymeric membranes (and possible blending), inorganic membranes, mixed-matrix membranes, and emerging two-dimensional-material membranes. Among these membrane materials, we discuss the ones providing the most relevant performance in separating ethanol from the liquid systems of water–ethanol and ethanol–water, among others. Furthermore, this review identifies the challenges and future opportunities in material design and fabrication techniques, and the establishment of structure–performance relationships. These endeavors aim to propel the development of next-generation pervaporation membranes with an enhanced separation efficiency.

“…From the point of view economic, adopting low‐cost ceramic support made from geomaterials such as clay, phosphate, and pozzolan rather than commercial support made from alumina, titania and zirconia, significantly reduces the total cost of the composite membrane 17 . For example, natural pozzolan is not only cheaper raw material but also requires lower sintering temperature of around 950°C 18 .…”

“…From the point of view economic, adopting low-cost ceramic support made from geomaterials such as clay, phosphate, and pozzolan rather than commercial support made from alumina, titania and zirconia, significantly reduces the total cost of the composite membrane. 17 For example, natural pozzolan is not only cheaper raw material but also requires lower sintering temperature of around 950 C. 18 In addition, the more the sintering temperature is low the less the amount of CO 2 emission is released, leading to green membrane preparation. Furthermore, the pozzolan support exhibits high permeability of 1982 L h À1 m À2 bar À1 , good porosity (33%) and excellent mechanical strength.…”

A new low-cost composite ultrafiltration membrane made of polysulfone (PSf) and polystyrene (PS) blend was effectively achieved on the ceramic pozzolan support using dip-coating method. The effect of PS content (5-20 wt%) on membrane properties such as microstructure and filtration performances was investigated. The Fourier-transform infrared spectroscopy, nuclear magnetic resonance, and differential scanning calorimetry analyses confirm that the two polymers lead to physical blend. The morphology analysis shows that PSf/PS membrane layer is homogeneous and strongly adherent on the pozzolan support. Furthermore, the developed membrane was applied for filtration of direct red (DR80) and methyl orange (MO) solutions at a pressure of 3 bar. It was proven that the PS addition significantly enhances the rejection of the membrane companying with a decrease of permeate flux to meet the trade-off selectivity-permeability. The optimized PSf/PS membrane containing 5 wt% of PS has a water permeability of 24 L h À1 m À2 bar À1 , and could reject 91% and 76%, respectively for DR80 and MO. Beside the promising filtration results, the developed membrane is also low-cost thanks to using pozzolan support, and it could be consequently scaled up for the treatment of colored wastewater generated from textile industries.
