An empirical approach is reported to reduce fouling through surface modification by rf-cathode sputtering and plasma deposition. Different effects on ultrafiltration and microfiltration membranes have been found. In a second approach, by application of pulsatile flow the transmembrane flux of ultrafiltration membranes could be improved up to 50%.enfiltrationMembranOberflächenmodifikationPolarisation610620660541journal article
