Description	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/m2) were used for filtering E. coli from artificial wastewater. Tests were carried out at 50 and 100 kPa pressure. Bacterial contamination was analyzed by both cultivation in nutrient agar medium and by flow cytometry (FCM). Both methods showed low pathogen removal efficiency (log 0.88 to 0.98) using filter materials ranging from 0.3 to 1.9 g/m2, and high removal rates (log 4.10 to 4.86) using filters of 3.8 g/m2 area weight, results comparable with the best commercial microfiltration membranes.
