Water purification and biomineralization using nanofibres-based membrane technology

Population of world and industrialization are increasing rapidly due to which the amount of fresh water is decreasing. There is a need to promote a novel cost-effective technique to purify the contaminated water. Nanotechnology provides extraordinary nanomaterials with unique properties which can be used to purify the water. In this article the use of polymeric hybrid membranes is discussed. A novel high flux filtration hybrid membrane system, consisting of a three-layer composite with hierarchical structures, i.e. highly porous hydrophilic material coated top layer, an electrospun nanofibrous barrier layer in the middle; for support the bottom layer is made of nonwoven fibrous web to provide high tensile strength up to 40 MPa, more durability and high retention ratio.
