摘要: Abstract Polyvinylidene fluoride (PVDF) blended with polymethyl methacrylate (PMMA) was electrospun into nanofibrous membranes, which had a mean pore size of 0.45 μm. The pure water permeability the prepared membrane higher compared to previous reports in conventional cast membranes equivalent and contact angle were characterized for purposes domestic industrial uses. Microscopic diagnoses also conducted characterize physical morphological natures membrane, revealed that much smoother than membranes. increase resistance filtration negligible up 16 days without cleaning secondary effluent; however this not case when used bioreactors. Suspended solids effluent completely removed, 48% removal chemical oxygen demand achieved. Pilot-scale testing PVDF–PMMA on from Seoul Zoo wastewater treatment plant (12 m 3 d − 1 ). Our results has potential become mainstream application post-treatment effluent, could lead us explore use diverse applications.
