Cost effective water purification technology in developing countries like India is always welcomed.So this paper presents about cheap nanomaterials with high performance to treat water .Out of 4 main parts it consist,(i.e) first one is air cathode microbial fuel cell (MFC) which removes about 80% (COD,BOD)chemical and biological Oxygen demand. Secondly, Ultrafiltration(UF) membranes made of polysulphone and silver nano particles embedded into it,which filters out inorganic salts. Thirdly, photocatalysis part made of titania and graphene oxide which filters almost all organic contaminants but not inorganic salts. Last but not the least, biopolymer reinforced nano composite composed of aluminium-oxyhydroxide-- chitosan composite which filters all remaining traces of heavy metals and also mainly bacteria and viruses of less than 1 micron.
