Abstract
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 Ø=α×[A+B×log(K×t/K)]; in which α is a coefficient between 0.85 and 1.15, and A=−21570×ent−18.6×D+19.0×e−2.5×e+0.1244 B=−11760×D×e+9.7×e+3.1×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.
