Abstract

In this study, the behavior of a Polyvinyl chloride (18 wt % PVC) hollow fiber ultrafiltration (UF) membrane for methyl green (MG) dye removal from aqueous solution was estimated by studying the influence of varying the operation conditions (the concentration of the dye and volumetric flow rate) to determine their impact on the separation processes (permeate flux and rejection coefficient) at constant pressure and temperature. The PVC membrane was characterized by scanning electron microscopy. Furthermore, tests of the UF were carried out with pure water and MG aqueous solutions as feed. Outcomes explained a notable influence of feed concentration and flow rate on the rejection and permeate flux, with the highest rejection coefficient value close to 75.2% of the membrane system, at neutral pH.
