Anordning för luftning av vattendrag eller avfallsvatten.

摘要

An apparatus for aerating water bodies, such as ponds, or of wastewater contained in a bioactive sludge basin, said apparatus comprising at least one air supply duct floating on the water and anchored as by means of a rope to opposite banks, and a plurality of spaced aeration units branching off of said air supply duct and extending down into the water, each aeration unit including an aeration body for instance in the form of a ceramic "candle" for introducing the air into the water, and a connection duct attached to the air supply duct for connecting it to said "candle". The invention enables an apparatus of this type to be readily installed and universally employed without impairment of its function by providing that each of said connection ducts is formed as a flexible hose.
