✦ Synopsis

In this paper the main techniques (microscopy observations, molecular weight cut-off determinations, porosity measurements) for characterizing ultrafiltration membranes are critically reviewed and discussed . Particular attention is devoted to the problem of evaluating the porosity of the membrane skin layer .

Porosity results obtained by testing some commercial ultrafiltration membranes with an automatic instrument based on the combined bubble pressure and solvent permeability method are reported .

Surface-charge-mosaic-modified ultrafiltration membranes with charged domains of various sizes (500, 100, or 50 mm) were prepared by two-step laser-induced surface graft polymerization using a striped photomask. First, the surface of an ultrafiltration membrane was treated with 4-vinylpyridine after

Several membranes have been tested in a test loop especially built in order to achieve well-defined flow conditions at the membrane surface. A test solution of dextran was ultrafiltrated at 0.5 MPa and 25°C at five circulation velocities from 5 m/s to 1 m/s. This corresponds to Reynolds numbers of 2
