Treatment of Effluents from the Textile Industry through Polyethersulfone Membranes

Abstract: Membranes have been widely used in the treatment of industrial effluents. However, there are still some limitations in the separation and permeability with respect to these effluents. Therefore, this study investigated the addition of 1% and 5% of an inorganic filler (clay) in polyethersulfone polymer membranes. By contact angle analysis, it was observed that the clay influenced the hydrophilicity of the membrane. The presence of the clay had an important role in the morphology of the membrane, modifying and f… Show more

“…The elongation decreases (7.67 ± 1.44 and 7.88 ± 1.44%, respectively). The increase in mechanical properties (tension) at the medium (GO-Arg 0.25%) and high (GO-Arg 0.50%) concentration in the GO-Arg embedded membranes is attributed to the formation of an intercalated structure between the additive and the polymer matrix, which depends on good dispersion and compatibility, 8,36 as well as the interaction of these during the process of making the membrane with the non-solvent (phase inversion). 32 The combination of the rigidity of GO-Arg and the flexibility of PES creates a hybrid material with higher resistance to rupture.…”

“…The PES membrane conformation can be commonly influenced by the polymer concentration and the transference of solvent to non‐solvent during the phase inversion process, aiming to produce mixed matrix membranes. However, the PES membrane is limited by its hydrophobic capacity, resulting in high fouling problems and water flow efficiency 8 . To resolve this problem, the formulation of PES with additives, such as graphene oxide (GO), 9 titanium dioxide, 10 tungsten oxide, 11 iron oxide, 11 zinc oxide, 12 silicon oxide, 13 and silver nanoparticles, 14 allows the transference of the intrinsic properties of nanomaterials, inducing significant changes in membrane morphology, such as characteristic finger‐like arrangement obtained during the membrane fabrication.…”

“…Ou seja, o fenômeno da incrustação pode ter ocorrido principalmente nas membranas com alumina. Isso pode ser percebido pois a membrana pura obtém um fluxo maior e as membranas com alumina obtiveram fluxos menores principalmente a membrana com 5% de alumina (Barbosa Ferreira et al, 2019). No entanto, mesmo com um fluxo menor estas membranas com alumina mostraram melhorias em sua eficiência, no que se refere à quantidade de partículas do corante retidas.…”

“…This may be related to the possibility that the high polymer concentration may obstruct the membrane pores, compromising the passage of the water. These phenomena may have occurred due to the fact that the high polymer concentration contributes to the formation of a larger dense membrane layer, as observed by SEM, which dramatically increases the water permeation resistance [35,36].…”
