“…These studies show that membranes "0" show biostatic The aim of our research was to obtain composite membranes with biocidal properties that could be used in water disinfection processes. In the literature, there are many examples of polymer composites containing an rGO addition that have biocidal properties [14,35]. Therefore, we conducted microbiological tests on rGO/PAN composite membranes obtained in the experiment.…”

The paper presents a method of obtaining composite polyacrylonitrile-based (PAN) membranes with the addition of reduced graphene oxide (rGO). The membranes were obtained using phase inversion method from a homogeneous rGO dispersion in a solution of PAN dissolved in N, N-dimethylformamide (DMF). The impact of the amount of rGO addition to the PAN matrix on the physicochemical, structural, transport, and separation properties and on fouling resistance was studied. Composite membranes, due to the method of preparation used and the addition of rGO, are characterized by very good transport properties (~390 L/m2 h) and by a high degree of protein retention (85%). Reduced graphene oxide has biocidal properties, which, as we have shown, depend on the size of nanoparticles and the type of microorganism. rGO/PAN membranes, on the other hand, show biostatic properties against Gram-negative bacteria (Escherichia coli), Gram-positive bacteria (Staphylococcuc aureus) and fungi (Candida albicans). Thus, the obtained composite membranes can be potentially used in water disinfection.

“…1,2 This is expected to get worse in the coming years, 3 unless efficient water purification methods are developed while minimizing the use of hazardous/toxic chemicals and impact on the environment. [4][5][6][7][8] In this scenario, two-dimensional (2D) materials are gaining massive appeal for the realization of novel membranes for filtration, 9,10 water purification 11,12 and desalination technologies. [11][12][13][14][15][16][17][18] As keycases, graphene based-membranes can provide cost-effective solutions for precise and ultrafast ionic and molecular sieving in aqueous solution.…”

“…The advanced graphene nanomaterials membranes are the most widely used technology in recent days and it has been classified in to two different structures: 1.Monolayer graphene membranes and 2.Stacked multilayer graphene membranes. The Monolayer graphene membranes are weaker in its mechanical strength and it is too difficult to prepare the nano -pores [13] when compared to the multilayer graphene membranes. Even the Helium (He) is the very smallest molecule which cannot pass through the monolayer graphene membranes [7].…”

The suspended and dissolved particles presented in the water and wastewater in the size of 1-1000 nm which is more toxic and it causes severe effects to the aquatic life and living organisms. Nanotechnology is the method, which is newly developed in this world, to remove the very tiny particles presents in the water as well as wastewater with the help of nano-particles. Many nano-particles were used to remove the toxic contents presented in water and wastewater such as heavy metal concentration, dyes and some of the virus and bacteria etc. Compared to various nano-materials, Graphene is the type of smart material which is derived from the graphite, most widely used in all industrial sectors for various purposes. This review paper discussed about the importance of graphene usage in water and wastewater treatment technologies in recent days.
