<p>A device (1) for introducing gases into liquids, especially air into waste water, having gas distributors (2) consisting of a longitudinal chamber (20) covered with a porous foil (19) arranged beneath the surface of the liquid, to which gas is fed through a supply pipe (5) and emerges into the liquid through the foil in the form of fine bubbles. The gas distributors (2) are connected to supply pipes (5) intended for a group of gas distributors (2) which have a base wall of rigidly stable material, preferably metal, forming one side of the chambers (20) covered with the porous foil (19). It is furthermore preferable for the gas distributors (2) to be fitted longitudinally on at least one side to bearers (7, 7a) arranged on the bottom of a tank or container holding the liquid.</p> |
