摘要 |
Arranged packings made of plastic are known whose strips have the same cross-section over their length and are joined together via a transverse holder web. The strips are arranged one above the other in a plurality of layers to increase the strip density. In the packing according to the invention, the strips are decreased in cross-section at least in the region of the holder web and preferably immediately to the left and/or right adjacent to the holder web. Thus the strips can be arranged in a layer with increased effective strip density. Packings formed in such a way serve for biological wastewater purification. <IMAGE> |
