UPFLOW SLUDGE BLANKET [3 records]

Record 1 2015-03-30

English

Subject field(s)
  • Wastewater Treatment
DEF

Advanced anaerobic digester in which the cells form flocs which are kept in suspension in the lower part of the reaction tank in the form of a bed.

OBS

The system is used with a liquid feed for waste material in solution. The feed stream is introduced at the base of the fermenter so that it passes slowly up through the bed.

French

Domaine(s)
  • Traitement des eaux usées
DEF

Type de digesteur en continu dans lequel la biomasse méthanique est maintenue dans le digesteur grâce à des caractéristiques exceptionnelles de floculation et à une grande vitesse de sédimentation.

Record 2 2001-08-20

English

Subject field(s)
  • Biochemistry
  • Wastewater Treatment
CONT

UASB [Upflow Anaerobic Sludge Blanket] is a process used for the biological treatment of effluents. It is based on the principle of an upflow anaerobic sludge blanket digester... Main advantages :-Sludge blanket improves contact between waste water and biomass, therefore efficiency of decomposition process-Improved product quality-Increased biomass concentration in reactor by formation of pellet sludge-Direct reuse of biogas calorific value is possible-No generation of secondary waste or concentrate streams.

CONT

Water Treatment Plants and Operations. Improvement of the Turbidity Removal by Internal Pellet Recirculation in a Pelletisation Process.

French

Domaine(s)
  • Biochimie
  • Traitement des eaux usées
DEF

Forme particulière de floc.

OBS

Ce support (le support des microorganismes de lits fluidisés) peut être : - des particules fines (sable) - des microparticules - ou les microorganismes eux-mêmes sous forme de «pellets». (Le traitement des rejets par voie anaérobie, 1980, p. 14).

DEF

An anaerobic digester which combines an upflow granular sludge blanket(UASB) and plastic ring media.

French

Domaine(s)
  • Sciences biologiques
  • Énergie de la biomasse
DEF

Type de digesteur en continu combinant un lit de boues granuleuses à flux ascensionnel et un filtre à supports plastique (anneaux).
