Erna Yuliwati,Ahmad Fauzi Ismail +1 more
TL;DR: In this paper, the effect of pore-forming hydrophilic additives on the porous asymmetric polyvinylideneflouride (PVDF) ultrafiltration membrane morphology and transport properties for refinery produced wastewater treatment was investigated.
Journal ArticleDOI
Effect of modified PVDF hollow fiber submerged ultrafiltration membrane for refinery wastewater treatment
Erna Yuliwati,Ahmad Fauzi Ismail,Takeshi Matsuura,Takeshi Matsuura,Mohd. Azraai Kassim,Mohd Sohaimi Abdullah +5 more
TL;DR: In this article, LiCl·H2O and TiO2 contents were used to study the effects of surface properties on membrane performance and the results showed that interactions between the membrane surface and suspended solid constituents strongly influenced membrane fouling.
Journal ArticleDOI
Characterization of surface-modified porous PVDF hollow fibers for refinery wastewater treatment using microscopic observation
Erna Yuliwati,Ahmad Fauzi Ismail,Takeshi Matsuura,Takeshi Matsuura,Mohd. Azraai Kassim,Mohd Sohaimi Abdullah +5 more
TL;DR: In this article, the surface structure of porous polyvinylidene fluoride hollow fiber membranes was investigated using microscopy and atomic force microscopy to determine the average pore sizes and surface roughness parameters and nodule sizes.
Journal ArticleDOI
