Improvements in the Structure of Electrospun Polyurethane Nanofibrous Materials Used for Bacterial Removal from Wastewater

While the properties of electrospun nanofibrous materials appear promising for filter applications, the ideal material parameters for water filtration are still being investigated. Polyurethane (PU) nanofiber layered on a supporting polypropylene (PP) textile is a good candidate for pathogen removal from water. Here, we show experimentally that pathogen removal from wastewater up to log 4.86 can be achieved using electrospun PU nanofibers. Materials with different area weights (0.3, 0.5, 1.9 and 3.8 g/m 2 ) were used for filtering E. coli from artificial wastewater. Tests were carried
