  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 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.
