Abstract

Hose for aeration of a flow medium, such as in biological sewage processing is free of perforations at the free ends of the hose (1) in the zone (T) around its periphery where it is connected to a tail end (2). Other sections have wall zones free of perforations, which lie diametrically opposite when the hose (1) is pressed together into a kinked point.
