On the Determination of Local Reverse Osmosis Membrane Properties from Optical Boundary Layer Measurements

227 Seiten, Dissertation Technische Universität München (2019), Softcover, A5

Zusammenfassung / Abstract

The performance data of Reverse Osmosis membranes can vary significantly. The main reasons are local variations of material properties and membrane testing conditions. To determine membrane performance parameters with high local resolution, a new methodology was developed and validated. The inverse method combines conventional lab-scale membrane tests with optical boundary layer measurements visualizing mass transfer through the membrane. The combination of the experimental methods with computational fluid dynamics (CFD) and optical ray tracing makes the investigation of local mass transport phenomena possible.
