Described is a gas-introduction device designed to introduce a gas into a liquid. The device comprises at least one gas-feed manifold (10) and a multiplicity of tubular feed-in elements (12) which are open at the free end. Each feed-in element is surrounded by a perforated tubular membrane (14). A gas-supply line in each feed-in element terminates in the vicinity of the membrane. Each feed-in element comprises two support elements (46, 48) extending out from a central element. The central element has a flange which is designed to be fastened to the outside of the gas-feed manifold. A gas-supply line leads from a bore in the gas-feed manifold, via a central line (26) and two branch lines (28) leading off the central line (26), into longitudinal grooves behind the membrane. The central line and the branch lines are located in the central element. The feed-in element is a monobloc construction including the central element and the membrane-support elements.

An aeration device which introduces a gas into a liquid, especially waste water which is to be treated, with at least one gas distributor (10), a number of supports (46, 48), each of which is open at their free ends and covered by a perforated, hose-shaped membrane (14), whereby each support (46, 48) is provided with at least one gas outlet which terminates near the membrane (14), whereby the supports (46, 48) project from a central body (24) attached to the gas distributor (10) and to which the gas can flow from the gas distributor (10) through a bored hole (34) and whereby the supports (46, 48) form a single piece as an inlet body (12), characterized in that the gas outlet is a gas feed channel (16) in the shape of longitudinal grooves in each support (46, 48), that the central body (24) is provided with a central channel (26) and two secondary channels (28) extending from it and the latter lead to the gas feed channels (16) in the shape of longitudinal grooves, and that the gas can flow from the gas distributor (10) to the central channel (26) through the bored hole (34).
