    摘要: A method of extracting a liquid phase from a suspension, the method comprising: injecting said suspension into a duct presenting a first section that is straight and a second section that is curved; and at the outlet from said curved section of the duct, extracting a liquid-enriched fraction of said suspension that is spatially separated from a particle-enriched fraction of the suspension; the method being characterized in that the injection flow rate of the suspension and the geometry of the duct are selected in such a manner that: in the straight section, lift forces cause particles to be superconcentrated in a ring around the longitudinal axis of the duct; and in the curved section, Dean secondary flows deform said ring and give rise to spatial separation between said liquid-enriched fraction and said particle-enriched fraction. A device for implementing such a method.

    摘要: Process for the production of asymmetrical microporous membranes by double irradiation.A membrane (5) is exposed to two irradiations, whereof one has an inadequate energy level to pass through the same, whereas the other passes through membrane (5).The irradiations produce molecular defects, which are attacked or etched in preferred manner by certain chemical agents. Thus, two networks of pores are obtained, one network being of large diameter and of a non-issuing nature (26), the other being smaller (27, 28, 29) and which issue on to the two surfaces (31, 32) of membrane (5).Application to filtration and sterilization.
