摘要：

This paper presents filtration results obtained with commercial acetate membrane with a pore diameter of 0.45 mu m, unmodified and modified with TiO2, bearing in mind drinking water treatment. The experimental filtration set-up that was used consisted in the gravitational filtration system, whereas the accomplished tests that were endured consisted of hydraulic permeability of the modified and unmodified membranes, treatment of polluted water with E. coli bacterium, color removal, turbidity and free chlorine. The results of hydraulic permeability showed similar flux for all membranes at the end of the experiments, between 25 and 30 kg.m(-2).h(-1). The retention results for color, turbidity and E.coli bacteria are comparable.
