Enhanced anti-fouling behavior and performances of nano hybrid PES-sio2 and pes-zno membranes for produced water treatment

This research is implemented primarily to obtain the enhanced performance in terms of permeability,solute rejection and anti-fouling behavior of pes membrane towards produced water treatment by incorporating nano-sio2 and nano-zno as nano inorganic filler. the fabricated membrane was modified through uv irradiation and immersion in acetone-ethanol mixture. the effect of several modification treatments is investigated in this study. nano hybrid pes-sio2 and pes-zno membrane were prepared using loeb-sourirajan methods (nips phase inversion). the casted membrane was exposed under uv lights for 2 min and followed by immersion in acetone-ethanol mixture for 24 h. the result of sem and ftir analysis confirmed that the nano particles incorporation change the membrane surface structure,while uv treatment and ac-et immersion significantly enhanced the hydrophilicity of membrane material. nano hybrid membrane displayed high efficiency of oil removal up to >99%,the immersion in the ac-et increased the water permeability about 20% and caused slightly decrease in solute rejection. the modified nano hybrid membrane performed an anti-fouling behavior in produced water filtration process. © 2017 penerbit utm press. all rights reserved.
