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 ...

The importance of wastewater treatment is growing rapidly with the populationпїЅs need of access to pure water and industrial process water. Different wastewater treatment technologies are available worldwide but the membrane treatment technology has earned popularity in the last decades because of cost/efficiency reasons. Polymeric membranes lead the market in membrane manufacture because they are very competitive in performance and economics. Polysulfone is one of the most used membrane material and has advantag...

Membrane processes used in wastewater treatment are categorized as the best techniques available at this time because it has advantages in terms of quality and costs. The membranes have different properties depending on the obtaining parameters. Their properties can be influenced throughout the membrane fabrication steps: when the polymer solution is prepared, when the polymer solution is applied in form of a thin film and also even after the thin film membrane is removed from the coagulation bath. Some important ...
