ANORDNUNG ZUM ENTFERNEN DES AUSFLOTIERTEN SCHLAMMES BEI BIOLOGISCHEM AKTIVATIONSREINIGEN VON ABWAESSERN UNTER ANWENDUNG DES FLUIDEN FILTRIERENS

摘要

Arrangement for biological activating cleaning of waste waters having a separating space and an activating space, the separating space being disposed above the activating space in a single container. The arrangement permits a surface take-off of cleaned water without reduction of the capacity for water treatment of the arrangement. In case part of the biocenology of the activated sludge becomes extinct or impaired, the arrangement permits an easy removal of sludge separated by floating from the surface of the content of the separating space.
