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.

Monolithic membrane filtration structure

A filter element, a particle filter, a method for marking a filter element, a method for producing a particle filter and the use of a filter element are described. With such methods and filter elements, individual filter elements can be securely adhered in a simple manner to form a filter. An identification means is applied to the end surfaces of each filter element for producing a particle filter, thus enabling the defined orientation of the filter elements for the adhesive process and preventing erroneous adhesion.
