Recent Studies from Korea University Add New Data to Desalination (Electrospun nanofibrous PVDF-PMMA MF membrane in laboratory and pilot-scale study treating wastewater from Seoul Zoo)
By a News Reporter-Staff News Editor at Journal of Technology -- Data detailed on Desalination have been presented. According to news reporting originating from Seoul, South Korea, by VerticalNews correspondents, research stated, "Polyvinylidene fluoride (PVDF) blended with polymethyl methacrylate (PMMA) was electrospun into nanofibrous membranes, which had a mean pore size of 0.45 mu m. The pure water permeability of the prepared membrane was higher compared to previous reports in which conventional cast membranes with equivalent mean pore size and,contact angle were characterized for the purposes of domestic and industrial uses. Microscopic diagnoses were also conducted to characterize the physical and morphological natures of the nanofibrous membrane, which revealed that the prepared membrane was much smoother than conventional cast membranes."
Our news editors obtained a quote from the research from Korea University, "The increase in resistance to filtration was negligible up to 16 days without membrane cleaning for filtration of the secondary effluent; however this was not the case when the membranes were used for bioreactors. Suspended solids in the secondary effluent were completely removed, and a 48% removal of chemical oxygen demand was also achieved. Pilot-scale testing of the electrospun nanofibrous PVDF-PMMA membrane was also conducted on secondary effluent from the Seoul Zoo wastewater treatment plant (12 m(3) d(-1))."
According to the news editors, the research concluded: "Our results revealed that the nanofibrous membrane has the potential to become a mainstream application in post-treatment of secondary effluent which could lead us to explore the use of nanofibrous membranes for diverse applications."
