FLOTTOER-LUFTARE.

摘要

The invention relates to a floating aerator for introducing air into a stretch of water, in particular an activated sludge plant, having at least one air supply line extending over the water surface and at least one base aerator which is suspended below the water surface by means of a float mounted on the air supply line and at least one connecting line branching off from the air supply line and which introduces air into the stretch of water at that point. To simplify mounting and to improve the operation of such floating aerators, the invention proposes that the air supply line is constructed as a continuous hose line (3) and that the float comprises at least two shaped parts (6, 7) which form a float and which are mounted on the hose line and enclose the hose line (3) completely or partly in a through opening formed by the shaped parts. ……
