| Abstract: | A new ultra-filtration membrane has been developed using indigenously available polymer, low cost solvents and a simple
casting technique. The performance evaluation of the developed membrane in terms of pure water permeability (PWP), flux
and rejection as compared to commercially available national and international membranes was carried out. It is observed that the newly developed membranes show acceptable performance both in terms of flux and rejection. The compressibility characteristic of the new membrane shows an improvement after suitable chemical modification through cross-linking reactions.The application perspectives of the membranes developed in our laboratory have been evaluated for the selective separation of dyes from typical textile waste stream of polyester fibre dyeing units with an aim to recover and recirculate the auxiliary chemicals and water in the process house. The rejection of dyes >98% and the permeate flux (0.8–1.0m3/m2 per day) values obtained for a specif... |
