Abstract
The solution for water scarcity problem can be accomplished by treating the domestic & industrial wastewater with different treatment 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 with N-methyl pyrolidone (NMP) as a solvent and Sodium Lauryl Sulphate (SLS) and water mixture as a non-solvent. The morphology and pore size were analysed by Scanning Electron Microscopy (SEM). The crystallinity was verified with the help of X-Ray Diffraction Techniques (XRD) and the identification of organic and inorganic groups were done using Fourier Transform Infra-Red Spectroscopy (FTIR). The pure water flux rate analysis was carried out for all the membrane with vacuum 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 surface membrane. The pore size and number of pores increased with the addition of inorganic materials. The results show that the moderate reduction in Total Suspended Solids (TSS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Dissolved Solids (TDS), chlorides etc.
