ABSTRACT:
The invention relates to a packing device for an installation for the biological treatment of waste waters, of the type comprising an assembly of sheets (1) having corrugations and separated by flat sheets (2), said corrugated sheets (1) defining, in conjunction with the flat sheets (2), channels (7;8) which extend from top to bottom, and in which the waste water trickles countercurrently to an oxygen-containing gas. This device is characterized in that the crests of the corrugations have crenellations (9) which in conjunction with the adjacent flat sheet (2) bound passages establishing communication between two channels (7, 7 or 8, 8) lying on the same side of a corrugated sheet.
