AB This work aims to study the characterization of several membrane filters by using capillaryflow porometry (CFP) and liquid extrusion porometry (LEP) to obtain their pore size distributions(PSD) and mean pore diameters (davg). Three polymeric membranes of di erent materials namely,polyethylene (PET), cellulose nitrate (CN), and FM (face mask), and one inorganic (namely, aluminaAl2O3) from ultrafiltration (UF)/microfiltration (MF) and particle separation were analyzed usinga pressure constant fluid/liquid extrusion porometer, developed at institute de la filtration ettechniques séparatives (IFTS). Several porosimetric fluids have been used to wet and penetrate intothe porous/fiber structure. The results show the accuracy of the setup on characterizing membranesin the UF/MF range by CFP, with reasonable agreement with nominal data of the filters. Additionally,LEP extension of the equipment obtained good agreement with nominal data and the CFP results,while filters presenting a microstructure of highly interconnected pores (face mask) resulted in cleardi erences in terms of resulting PSD and average sizes when CFP and LEP results are compared.
