FIELD: process engineering.
SUBSTANCE: invention relates to lattice structure with crosswise and lengthwise webs, and to filter cartridge incorporating said structures. Lattice structure 1 for passage first fluid at resistance of second fluid incorporates crosswise webs 20 and lengthwise webs 10. Note here that lattice holes 4 with inner width < 300 mcm are arraged between crosswise webs 20 and lengthwise webs 4. At least lengthwise or crosswise webs on one lattice structure side 2, 3 have system of ribs 8, 8a, 8b extending perpendicular to lattice plane 6 of ribs 31, 32, 41, 42. Note here that, at least one first group 30 and one second group 40 of ribs 31, 32, 41, 42 that differ in at least their height H1, H2, at H1 > H2. Invention relates also to container 50 with at least one water feed opening 54 and one air exhaust opening 55, both being provided with lattice structures 1.
EFFECT: higher efficiency of filtration.
