Membrane operations in the last years have shown their potentialities in the rationalization of production systems and it has been studied extensively as a result of the fast and energy efficient process without any phase changes. However, a major inefficiency for the membrane processes is fouling, which causes a decrease of membrane permeability and performance. It is necessary to develop effective procedures to decrease of membrane fouling and increase permselectivity. Using of specific nanomaterials is offering powerful tools for the purpose of flux improvement and better antifouling properties in polymeric membranes. In this project, novel hydrophilic 2D nanomaterial Bioten will be synthesized by exfoliation of Biotite and its effect on the antifouling properties and filtration performance of the phase inversion fabricated asymetric porous polyvinyl chloride (PVC) membrane will be investigated. The hydrophilicity, cross-sectional morphology, porosity, pore size, surface roughness, water permeation, salt rejection, protein and dye separation performance and flux recovery of the membranes will be studied. The optimized membranes will be used for the treatment of textile wastewaters. First, the nanomaterial will be synthesized and charaterized by FT-IR, XRD, XPS, SEM, TEM and BET. Next, these nanomaterial will be used in the fabrication of PVC polymeric membranes. The high flux membranes will be prepared with antifouling properties. The amount of nanomaterials in the matrix of nanocomposite membranes will be optimized.
