A monolithic membrane-type filtration structure for filtering liquids, includes a support formed of a porous inorganic material of permeability K, the support having a tubular overall shape with a main axis, an upstream base, a downstream base, a peripheral wall delimiting an internal part and a plurality of passages parallel to the main axis of the support, formed in the internal part of the support, a membrane of permeability Kand of mean thickness tcovering the internal surface of the passages; the external hydraulic diameter of the structure satisfying the relationship &#xd8;=&#x3b1;&#xd7;[A+B&#xd7;log(K&#xd7;t/K)]; in which &#x3b1; is a coefficient between 0.85 and 1.15, and A=&#x2212;21570&#xd7;ent&#x2212;18.6&#xd7;D+19.0&#xd7;e&#x2212;2.5&#xd7;e+0.1244 B=&#x2212;11760&#xd7;D&#xd7;e+9.7&#xd7;e+3.1&#xd7;e+0.04517. Dis the mean hydraulic diameter of the passages, eis the minimum thickness of the internal walls between the passages, eis the minimum thickness of the peripheral wall of the filter.
