Microfltration nanofibrous membrane for wastewater treatment

Pilot testing of nanofiber membrane module demonstrated long-term stability of the filtration process in activated sludge and showed the applicability in real-world conditions at the wastewater treatment plant. Microbial contamination of samples of the filtrate reached log removal 2 CFU/mL. Filtration in combination with UV irradiation resulted in a reduction of microbial contamination under required legislative standards. These results supported our assumptions to use nanofibre membranes in membrane bioreactor. Regeneration, optimization and antifouling surface treatment will be another step to increase the competitiveness of nanofiber membranes for water treatment
