The plant of the present invention includes three reaction vats (100, 200, 300) in series, each containing an aqueous phase and a specific bacterial population. The vats are used for sequentially solubilising the liquid feedstock to be treated by enzymatic hydrolysis, and biodegrading the resulting effluent by biological digestion, and finally reducing the residual bacterial components. The vats are isolated from each other by tangential filters (108, 208, 308) and centrifugal separators (212, 312) for filtering the biomass from the reaction products. The result is an essentially inorganic final liquid effluent (EFF/N), and the biomass filtered downstream is an ultimate organic waste (DU) having a reduced volume.
L' installation comprend trois cuves de réaction (100, 200, 300) en série, chacune contenant une phase aqueuse et une population bactérienne spécifique. Elles permettent, successivement, de solubiliser la charge liquide à traiter par hydrolyse enzymatique, puis biodégrader l'effluent résultant par digestion biologique, et enfin réduire les composants bactériens résiduels par action biologique. Les cuves sont isolées entre elles par des filtres tangentiels (108, 208, 308) et des séparateurs centrifuges (212, 312) pour filtrer la biomasse des produits de réaction. Le résultat est un effluent liquide final (EFF/N) essentiellement non organique, la biomasse filtrée en aval constituant un déchet organique ultime (DU) de volume réduit.
