PROCEDE ET DISPOSITIF POUR LE TRAITEMENT EN CONTINU DE LIQUIDES

摘要

Polluted liquids are treated by a bioflocculation process and the thus obtained floccular suspecsion is separated by filtration in a perfectly floating sludge blanket, whereby prior to filtration, the suspension, created in the course of the bioflocculation process, is subjected to a sedimentation, whereby a first stream obtained by sedimentation containing a diluted suspension is passed to be filtered in the perfectly floating sludge blanket and a second stream containing a concentrated suspension is returned into the bioflocculation process.
