Chitosan/Polyethersulfone Composite Nanofiltration Membrane for Industrial Wastewater Treatment

Chitosan/polyethersulfone (CS/PES) composite membrane was prepared from casting chitosan solution on polyethersulfone substrate membrane. The Substrate membrane was prepared by phase inversion technique using polyethersulfone (PES) and dimethylacetamide (DMAc) as solvent with and without the addition of polyvinylpyrrolidone (PVP) as pore-forming agent. The effects of the composition of the c...

An Autopsy of Nanofiltration Membrane Used for Landfill Leachate Treatment

Komurcuoda leachate treatment plant, Istanbul, which consists of membrane bioreactor (MBR) and nanofiltration (NF) system, faced rapid flux decline in membranes after 3-year successful operation. To compensate rapid flux decline in membranes, the fouled membranes were renewed but replacement of the membranes did not solve the problem. To find the reasons and make a comprehensive analysis, membr...
