Abstract
An apparatus for introducing gases in the form of fine bubbles into a fluid is described, in which a diffuser pipe for a perforated distributor hose is mounted on a gas supply pipe. The diffuser pipe is constructed in one piece, extends transversely across the gas supply pipe, and is attached to the same by means of clamping elements. An opening for the passage of the gas is provided between the diffuser pipe and gas supply pipe. A pair of plugs positioned in the diffuser pipe define a flooding chamber at each end of the pipe and a gas-carrying chamber positioned medially therebetween. The apparatus is particularly suitable for the aeration of activation tanks for waste water.
