The polymers performance in membrane technology provide a stable and very high
level of pollutant removal. The selection capacity and low cost of the polymeric
membrane technology are important factors in wastewater treatment applications. Four
membranes from polysulfone with different concentration blend in N-Methyl-2-
pyrrolidone were obtained by phase inversion method in our laboratory. The membrane
performances were characterized by flux rejection, relative flux, retention capacity and
morphology. The surface and cross-section morphology of the samples was observed by using scanning electron microscope, in order to correlate the membrane structures with permeation tests. The asymmetric structure consists in two distinct layers, sponge-like and finger-like formations with variable dense top layer. It has been observed that
surface porosity influences the retention capacity. Also, the anti-fouling ability was
examined for two dyes with different molecular weight: Congo red dye and Methylene
blue dye. Based on the results obtained, it is reported that the membranes with the high polymer concentration shows the highest retention, a well-defined top dens layer, lowest fouling and higher molecular cut-off.
