Abstract

Bei einer Vorrichtung zur Durchführung einer pneuma­ tischen Flotation bestehend aus einer Trennzelle mit einem Austrag für die Flotationsabgänge und mit einer Schaumfangrinne und zugeordnetem Austrag sowie aus wenigstens einem außerhalb der Trennzelle angeordneten und mit der Trennzelle verbundenen Begasungsreaktor für die zu flotierende Trübe sollen die in der Trennzelle beim Trübeeintritt auftretenden Turbulenzen vermieden werden. Hierzu ist vorgesehen, daß zwischen Begasungs­ reaktor (17) und Trennzelle (11) zum Abbau der Strömungs­ energie der belüfteten Trübe eine Beruhigungsstrecke (18) eingeschalten ist.
