Abstract

Um eine Flüssigkeit feingasig zu begasen, werden im Bodenbereich eines Beckens (10) Belüftungselemente (12) angeordnet, die über eine Gaszuführungsleitung (14) mit Gas beaufschlagt werden. Die Belüftungselemente sind Teil der Gaszuführungsleitung. Das Gewicht der Belüftungselemente mit der Gaszuführungsleitung ist so gewählt, daß besondere Befestigungen für die Gaszuführungsleitung nicht erforderlich sind.
