Hybrid Membranes of Polyamide Waste Obtained by Phase Inversion Technique

This work investigates the production of microporous wool hybrid membranes using polyamide 66 yarns from industrial waste and vanadium pentoxide (V2O5), with the aim of applying this technology in the treatment of effluents, especially in the removal of textile dyes. The membranes were produced by phase inversion and characterized by several tests, such as water absorption, porosity and microfiltration efficiency. The results showed that the membranes containing 3% and 5% V2O5 presented superior performance compared to the pure PA 66 membrane, achieving stabilized water fluxes above of 193 Kg.m-2.h-1 and high rejection coefficients, reaching 99.97%. These findings highlight the potential of hybrid membranes as an efficient and economical alternative for effluent treatment.
