Abstract

Das Verfahren dient zur Entfernung von Feststoffen mit Hilfe von Gasblasen (4) aus einer wässrigen Faserstoffsuspension (S), insbesondere Altpapiersuspension, wobei der Fasersuspension (S) in mindestens einer Mischvorrichtung (1) Gas (6) zugeführt und Gasblasen gebildet werden. Danach wird die begaste Suspension (S') aus der Mischvorrichtung (1) über einen einstellbaren Strömungswiderstand, insbesondere durch eine Drossel (4), in einen Flotationsbehälter (3) geführt, indem die Abscheidung von Feststoffen durch Flotation erfolgt. Das Verfahren ermöglicht die Einstellung des Luftgehaltes der begasten Suspension (S').
