Abstract : The importance of water purification has increased in most civilizations because of economic growth and significant industrialization. Many regions of the world will lack access to drinking water because of ongoing water shortages, such as pollution, industrialization, andurbanization.Recently, membranes for nanofiltration and reverse osmosis have both been used to treat wastewater, due to the increased contamination of fresh water by numerous pollutants such as dyes, pharmaceutical wastes, organic pollutants, and heavy metal constituents, which are generated by industrial, urban, and mining processes, all these are the primary causes of drinking water shortages. Thin film nanocomposite (TFN) membranes are regarded as the most effective membranes currently on the market for desalination and organic pollution removal. These membranes improve productivity and selectivityusing less energy than conventional asymmetric membranes. Herein, a superhydrophilic thin film nanocomposite was produced and was functionalized by graphene oxide grafted with Trimesic acid and melamine/polyoxometalates, the incorporation of the polyoxometalates (POMs) nanocomposite makes the membrane highly selective and shows a rejection of about 100% for pentane, and decane hydrocarbons, while when tested withSr2+, Co2+, Pb2+the membrane shows ~ 98% rejection, and around85% when tested with 4000 ppm of SO4 2-, attaining a flux of about 664Lm-2h-1 when tested with an applied pressure of 200KPa was applied across the area of the thin film nanocomposite. Surprisingly the membrane undergoes around 90% recovery after the first use and was sustainable when used with the synthetic water during subsequent tests.
