Title: | Elektrisch leitfähige Umkehrosmosemembranen zur Verminderung des Biofoulings | Other Titles: | Electrically conductive reverse osmosis membranes for the reduction of biofouling | Language: | German | Authors: | Nolte, Mathias C. M. | Keywords: | reverse osmosis;membrane;reduction;biofouling;carbon nanotube;electrical conductivity | Issue Date: | 2009 | Examination Date: | 3-Aug-2009 | Abstract (german): | Umkehrosmosemembranen auf der Basis von Celluloseacetat sowie aromatischem Polyamid wurden mit Carbon Nanotubes elektrisch leitfähig modifiziert. Durch Beaufschlagen mit einem positiven elektrischen Potential wurde die Belegung der Membranoberfläche mit dem Bakterium Staphylococcus warneri in etwa halbiert. Elektrostatische Kräfte wurden als hierfür ursächlich identifiziert. |
Abstract (english): | Reverse osmosis membranes based on cellulose acetate as well as aromatic polyamide were modified to be electrically conductive by utilising carbon nanotubes. By applying a positive electrical potential onto the membrane surface the amount of attached bacteria Staphylococcus warneri was reduced by about 50 %. Electrostatic forces were identified as the cause for the anti-fouling effect. |
