MRI on a new polymeric multichannel membrane for ultrafiltration

Membrane ultrafiltration in new polymeric multi-channel membranes designed for in-out filtration was investigated to get insights into structure, flow and properties. The apparent novelty of the membrane concerns geometry configuration feed channels. In-situ magnetic resonance imaging (MRI) allows non-invasive non-destructive investigations with adequate spatial time resolution. structure measured an in-plane resolution 35 µm/pixel revealing first polymer density distribution over 19-channel second wettability fiber its cavities different dimensions. MRI also used answer questions about consequently Finally, in-situ aqueous solution sodium alginate observed which led deposit formation at channel’s inner surfaces. kinetics this quantified. Backwashing flushing gave insight cleanability
