Microfltration nanofibrous membrane for wastewater treatment
Lev, J. ; Holba, Marek ; Došek, M. ; Kalhotka, L. ; Detvanová, L. ; Dostálová, L. ; Přichystalová, J. ; Vincent, I. ; Kimmer, D.
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.
Can Nanofibers Replace Current Microfiltration Materials?
Lev, J. ; Holba, Marek ; Došek, M. ; Kalhotka, L. ; Kimmer, D.
The electrospun nanofibrous material M247 can be used as antimicrobial filter. Laboratory tests show high removal value (up to 6 log10 CFU/mL) and similar filtration efficiency compared filter Pragopor 6, presently used for sterilization of liquids in laboratories. Semi-pilot test confirmed good mechanical endurance and high removal efficiency. Our study showed high removal value with non-functionalized nanofibrous material despite of other cited studies. These results confirm our expectations, that nanofibrous material can replace the current filtration materials for laboratory use.
