Abstract
Ultrafiltration (UF) membrane was prepared using the Manjikian process via phase inversion from casting five increasing polymer concentrations (cellulose acetate at 15, 16.5, 18, 19.5 and 21 wt.%), acetone and formamide (2:1) (v/v). The synthesized membranes were tested by Fourier transformed infrared spectroscopy, scanning electron microscopy, contact angle and porosity. The permeability was determined and the molecular weight cut-off was evaluated by the retention of polyethylene glycol. The results showed that the higher polymer concentration enhanced hydrophilicity of the membranes as well as decreased the molecular weight cut-off. The membranes demonstrated greater potential to retain pathogenic and epidemiological UroPathogenic Escherichia coli (UPEC) at higher polymer concentrations. The highest polymer concentration membranes were able to retain a total discharge of 8U-log bacteria.
