EXPERIMENTAL STUDY ON BACTERIA REMOVAL FROM ARTIFICIAL AND REAL WASTEWATER BY NANOFIBROUS FILTERS

Unique properties of electrospun nanofibrous materials could be utilized in various environmental technologies, e. g. bacteria removal from water. Recent studies show various removal efficiencies of bacteria and particulated matter by nanofibrous filters. Our article presents results from filtration tests through polyurethane nanofibrous material on short-term scale with artificial wastewater and also results from tests with real wastewater. We determined E. coli abundances in artificial and real wastewaters and the amount of the other hygienically important bacteria in real wastewater samples only. The results show possibility of long-term full-scale application of those materials; however some material modifications are needed to be accomplished.
