Activated sludge
Activated sludge is a process dealing with the treatment of sewage and industrial wastewaters. Basically atmospheric air or pure oxygen is forced into raw sewage (or industrial wastewater) combined with organisms to develop a biological floc which reduces the organic content of the sewage. The combination of raw sewage (or industrial wastewater) and biological mass is commonly known as Mixed Liquor. In all activated sludge plants, once the sewage (or industrial wastewater) has received sufficient treatment, excess mixed liquor is discharged into settling tanks and the treated supernatant is run off to undergo further treatment before discharge. Part of the settled material, the sludge, is returned to the head of the aeration system to re-seed the new sewage (or industrial wastewater) entering the tank. This fraction of the floc is called Return Activated Sludge (R.A.S.). Excess sludge which eventually accumilates beyond what is returned is called Waste Activated Sludge (W.A.S.). W.A.S is removed from the treatment process to keep the ratio of biomass to food supplied (sewage or wastewater) in balance. This is called the F:M ratio. W.A.S is stored away from the main treatment process in storage tanks and is further treated by digestion, either under anaerobic or aerobic conditions prior to disposal. Sometimes another term for W.A.S is S.A.S (Surplus Activated Sludge), both terms have the same meaning.

Boue activée
Le procédé dit « à boues activées » utilise l'épuration biologique dans le traitement des eaux usées. C'est un mode d’épuration par cultures libres. Dans une filière de traitement des eaux (i.e. les différentes phases d'épuration pour une station donnée), le procédé à boues activées fait partie des traitement secondaires

Belebtschlamm
Belebtschlamm oder belebter Schlamm nennt man die Ansammlung an Mikroorganismen, die bei der aeroben biologischen Abwasserreinigung organische Stoffe abbauen. Er besteht vor allem aus BakterienPilzen und Protozoen.Der Belebtschlamm ist in der Kläranlage beim Belebtschlammverfahren für die Nitrifikation zuständig. Wichtig ist vor allem, ihm genügend Sauerstoff zur Verfügung zu stellen. Der Belebtschlamm wird nach dem Reinigungsvorgang vom Abwasser getrennt und als Klärschlamm wieder verwendet.

Активный ил
Активный ил — один из методов биологической очистки сточных вод. Данный метод был изобретён в Великобритании в 1913 году. Биологическая очистка сточных вод осуществляется с целью удаления из них органических веществ, в том числе соединений азота и фосфора.
