<p>A packing element, for use in chemical and biological treatment apparatus, comprises a plurality of open-ended tubular members (1) symmetrically disposed about a central open-ended tubular member (3), the axes of all the tubular members being substantially parallel, and connected to the central tubular member by planar ribs (2), the planes of which are substantially parallel to the axes of the tubular members; each tubular member being provided with internal radial ribs (4) extending inwardly from their walls, and adjacent tubular members in the outer array being connected one to the other by webs (6) of generally V-shaped cross-section (as viewed along the axes of the tubular members) the apices of the V-shaped webs pointing outwardly from the central tubular member.</p> |
