The Effect of Polyethelene Glycol on The Performance of Polysulfone Membrane Blend with Silica From Rice Husk

Abstract

In the present work, the effect of rice husk silica (RHS) on the performance of polysulfone (PSf) blended with polyethylene glycol (PEG) membranes were investigated. The hybrid ultrafiltration membranes were prepared by phase inversion technique. The membrane performance was analyzed by using pure water flux, humic acid for the rejection test and followed by the membrane characterization. Results showed that PEG increased membrane pure water flux to 621.212 LMH and rejection humic acid at and 98%. The analysis of SEM revealed that PEG obviously changed the microstructure of the membrane especially at the top and sub layer.
