Title (EN) ORGANICS AND NUTRIENT RECOVERY FROM ANAEROBIC DIGESTER RESIDUES
(FR) RÉCUPÉRATION D'ÉLÉMENTS ORGANIQUES ET NUTRITIFS À PARTIR DE RÉSIDUS DE DIGESTEUR ANAÉROBIE
Abstract:
(EN) Sludge from an anaerobic digester is treated to recover one or more of fibers, or solids or liquids with a high nutrient content. The solids or liquids can be used as a fertilizer. The fibers can be used in a plant growing medium. Solids are separated from liquids in the sludge and dried. The solids may be dried to produce a flake or pellet. Ammonia in the liquids is recovered and used to produce a concentrated acidic ammonium salt solution. This solution may be mixed with the solids to produce a nitrogen enhanced solid. The fibers and solids or liquids can also be used in combination to produce an enhanced plant growing medium. A device and process for removing ammonia from a liquid can be used in the system or separately.
(FR) L'invention concerne le traitement de la boue d'un digesteur anaérobie pour récupérer une ou plusieurs fibres, ou solides ou liquides ayant une teneur élevée en éléments nutritifs. Les solides ou les liquides peuvent être utilisés en tant qu'engrais. Les fibres peuvent être utilisées dans un milieu de culture de plantes. Les solides sont séparés des liquides dans la boue et séchés. Les solides peuvent être séchés pour produire des paillettes ou des pastilles. L'ammoniac dans les liquides est récupéré et utilisé pour produire une solution concentrée de sel d'ammonium acide. Cette solution peut être mélangée avec les solides pour produire un solide enrichi en azote. Les fibres et solides ou liquides peuvent aussi être utilisés en combinaison pour produire un milieu de culture de plantes amélioré. Un dispositif et un procédé pour éliminer l'ammoniac d'un liquide peuvent être utilisés dans le système ou séparément.
