  Due to the increase in population and as a result of the increase in economic activities in the world, the demand for water consumption has increased significantly. Seawater covers two-thirds of the earth's surface, so it makes sense to use these resources to provide drinking water and could be an important component in solving the problem of water scarcity. In addition, existing technologies for water treatment to meet There are certain water quality requirements, so reusing used water to address water shortages can be further explored. In recent years, organic metal frameworks have received much attention due to their interesting chemistry and potential applications. In the science of separation, researchers have extensively studied organic-metal frameworks for gas separation and water treatment. In this paper, the aim is to investigate the possibility of using organic-metal frameworks for membrane desalination. Therefore, after a brief introduction of organic-metallic frameworks, several methods for preparing membranes of organic-metallic frameworks, water desalination techniques and methods of application of organic-metallic frameworks and finally membranes of organic-metallic frameworks for different applications of water Such as desalination, nanofiltration, ultrafiltration and microfiltration are considered. The use of organic-metal frameworks as membranes in water treatment is still in its infancy compared to other applications such as gas separation. Manuscript profile

  Cardiovascular diseases are the most common cause of fatality all over the world. A severe increase of low-density lipoprotein (LDL) concentration in blood is recognized as the main cause of coronary artery disease (CAD) and atherosclerosis. LDL apheresis from blood is one of the extracorporeal options for patients suffering from this disorder which drug therapy is not effective for them. LDL apheresis is classified in cascade filtration and adsorption-based methods. In this study further reviewing all LDL apheresis techniques, polysulfone (PSU) membranes for selective adsorption of LDL were investigated. By inspiring from inherent LDL receptor (LDLR) of body, different methods including heparinization of PSU membrane by various methods such as chloromethylation, treatment with ammonia plasma and co-deposition of polydopamine and polyethyleneimine can be used for adsorption of LDL from the blood. Also, membrane ionic glycosylation by click chemistry and grafting of alginate sulfate on the surface of PSU membrane to adsorption of LDL were reviewed. To investigate surface modification accuracy, different analyses such as X-ray photo spectroscopy (XPS), Attenuated total reflectance Fourier transform infrared (ATR-FTIR), -Potential and water contact angle are used. Blood compatibility is another factor for the development of these membranes for defined application. Manuscript profile

  Nanofiltration is one of the most widely used membrane processes for water purification with high practical value because of a large number of chemical species that are separated through this process. Usually, for nanofiltration, high energy–con- suming operations are involved including the generation of enough pressure for the rejection of jumps and lower molecular weight chemicals at the surface of the membrane. Recent developments in the synthesis of nanocomposite membranes with graphene and graphene derivatives have led to an increase in energy requirements and the increase in membranes perfor- mances. In the present review, we have presented the recent advances in the field of graphene-based composite membranes for nanofiltration with applications for both types of based solvents—aqueous solutions and organic solvents. The presentation will be focused especially on the performances of membranes and applications of these materials for the rejection of salts (Na+, Mg2+), heavy metals (Li2+), and lower molecular weight organic compounds (methylene blue, Congo red, Direct Red, Methyl orange, Reactive green 13, etc.). Modern synthesis methods like interfacial polymerization for obtaining thin-film composite nanofiltration membranes are also presented. Nanofiltration is one of the most widely used membrane processes for water purification with high practical value because of a large number of chemical species that are separated through this process.

  Over the years, conventional wastewater treatment processes have achieved to some extent in treating effluents for discharge pints. Development in wastewater treatment processes is essential to make treated wastewater reusable for industrial, agricultural, and domestic purposes. Membrane technology has emerged as an ideal technology for treating wastewater from different wastewater streams. Membrane technology is one of the most up‐to‐date advancements discovered to be successful in fundamentally lessening impurities to desired levels. In spite of having certain impediments, membrane bioreactors (MBRs) for biological wastewater treatment provide many advantages over conventional treatment. This review article covers all the aspects of membrane technology that are widely used in wastewater treatment process such as the principle of membrane technology, the classification of membrane technology processes in accordance to pressure, concentration, electrical and thermal‐driven processes, its application in different industries, advantages, disadvantages and the future prospective.

  The demand for rare earth elements has increased significantly due to potential industrial applications such as catalysts, magnets, battery alloys, ceramics. However, the separation and recovery of rare earth metals are very difficult due to their similar chemical properties and ionic radius, so progress in the separation process of these elements will bring many global benefits. Among the improved methods, the membrane technique has received much attention as a stable method with easy operation in the separation of such metals, and several membranes have been designed for separation. This article provides a summary of the types of membranes in the separation of rare earth elements in terms of extraction performance, transfer efficiency, and membrane stability. Polymer inclusion membranes are a new generation of non-liquid membrane that is made by a simple method of casting a solution containing liquid phases (carrier, plasticizer /modifier) and base polymers. Polymer inclusion membranes due to the possibility of simultaneous extraction and back-extraction, high selectivity, excellent stability, reusability, simple applicability, relatively low cost, and low energy consumption, it provides a great advantage in both the separation and purification of metal ions. Therefore, in this study, an overview of the PIMs reported in the studies to date is presented and the performance, permeability and stability of the membrane are discussed according to the base polymer, carrier, plasticizer and modifiers used.

  The presence of heavy metal ions in polluted wastewater represents a serious threat to human health, making proper disposal extremely important. The utilization of nanofiltration (NF) membranes has emerged as one of the most effective methods of heavy metal ion removal from wastewater due to their efficient operation, adaptable design, and affordability. NF membranes created from advanced materials are becoming increasingly popular due to their ability to depollute wastewater in a variety of circumstances. Tailoring the NF membrane’s properties to efficiently remove heavy metal ions from wastewater, interfacial polymerization, and grafting techniques, along with the addition of nano-fillers, have proven to be the most effective modification methods. This paper presents a review of the modification processes and NF membrane performances for the removal of heavy metals from wastewater, as well as the application of these membranes for heavy metal ion wastewater treatment. Very high treatment efficiencies, such as 99.90%, have been achieved using membranes composed of polyvinyl amine (PVAM) and glutaraldehyde (GA) for Cr3+ removal from wastewater. However, nanofiltration membranes have certain drawbacks, such as fouling of the NF However, nanofiltration membranes have certain drawbacks, such as fouling of the NF membrane.
