Biocide Modification of Ultrafiltration Membranes Using Nanofiber Structures

Popis výsledku v původním jazyce

Membrane biofouling has a negative effect on membrane performance. Commercial ultrafiltration (UF) membranes were therefore modified using polymeric nanofibers in order to gain additional water treatment functionality. In this case, membrane surface wasmodified using biocidal electrospun polyurethane nanofibers. It has been found that the inorganic silver in form of reduced silver nitrate is a feasible modification of nanofiber structure, and electrospinning conditions were optimized to maximize silverparticle content. Two possible methods were verified for preparing composite UF membranes with antibacterial properties using: (a) direct nanofiber deposition and (b) thermal pressure lamination. Hydrodynamic properties of the developed membranes were tested on an AlfaLaval M10 unit. It has been found that the added functionality comes at the expense of lower permeability. Biocide properties over both short- and long-term operation were confirmed through cultivation techniques and respi
