Filler bodies for the biological purification of, for example, waste water are fitted together from individual filler-body blocks. In this case, these have to be releaseably connected to one another. In known filler bodies, adapters are used for this purpose which obstruct the ability of the waste water to flow through or around the filler body. As a result, the cleaning capacity is also reduced. The filler body according to the invention has at least one tube of one or each filler-body block (21, 22, 23, 36, 40, 45) as a tube (31, 37, 38, 39, 56) which extends over a plurality of filler-body blocks (21, 22, 23, 36, 40, 45). As a result, the individual filler-body blocks (21, 22, 23, 36, 40, 45) are connected to one another in a positive-locking manner without the ability to flow through or around the filler body being obstructed. The filler body according to the invention is particularly suitable as a substrate for a so-called biological lawn for the biological purification of waste water or gases.

Filler body and method for its manufacture

Packing material for biological waste water treatment, and process for the production of such packing material. Packing material made of tube-shaped base members with net structured outer surface are provided with at least one water-impermeable surface-increasing element arranged on the outer surface of each base member and directly connected thereto, for increasing the specific growing surface for biofilm.
