초록
The solution for water scarcity problem can be accomplished by treating the domestic & industrial wastewater with differenttreatment techniques. In this study, Polyethersulfone (PES) membranes were prepared with 0%, 0.25%, 0.5%, 0.75% and 1%wt% of SiO2 and ZrSiO4 as two different modifying agents. Phase inversion method is used for membrane preparation withN-methyl pyrolidone (NMP) as a solvent and Sodium Lauryl Sulphate (SLS) and water mixture as a non-solvent. Themorphology and pore size were analysed by Scanning Electron Microscopy (SEM). The crystallinity was verified with the helpof X-Ray Diffraction Techniques (XRD) and the identification of organic and inorganic groups were done using FourierTransform Infra-Red Spectroscopy (FTIR). The pure water flux rate analysis was carried out for all the membrane withvacuum filtration setup. The performance of the different membranes was analysed with tannery effluent and textile effluent. SEM image shows a two-layered structure where the top surface is porous followed with the homogeneous bottom surfacemembrane. The pore size and number of pores increased with the addition of inorganic materials. The results show that themoderate reduction in Total Suspended Solids (TSS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD),Total Dissolved Solids (TDS), chlorides etc.
