Abstract
The invention relates to an aerator for introducing gas into liquids, in particular compressed air into waste waters (effluents), having a housing which encloses a distributor space provided with a connection nozzle, above which distributor space is arranged a plate or membrane. To improve the gas introduction and avoid deposits, such as sludge, according to the invention it is provided that not only the housing having the distributor space, but also the plate or membrane, are designed to be ring-like, preferably annular, having a central through-hole. <IMAGE>
