The invention concerns a method and a device for treating and upgrading raw manure. The method and the device comprise steps which consists in promoting agglomeration of solid constituents of the manure and precipitating the agglomerated particles using a sedimentation agent. More particularly, the sedimentation agent used is based on natural stone powder and/or industrial derivatives. The sedimentation of the agglomerated particles enables the solid phase and the liquid phase to be separately treated, leading optionally to the production of solid fertilizer, liquid fertilizer and water corresponding to environmental standards and capable of being released into the environment or readily recycled.
Un procédé et un dispositif permettant le traitement et la valorisation de lisier brut. Le procédé et le dispositif incluent les étapes de favoriser l~agglomération des composantes solides du lisier et la précipitation des particules agglomérées en utilisant un agent de sédimentation. Particulièrement, l~agent de sédimentation utilisé est à base de poussières de pierres naturelles et/ou de dérivés industriels. La sédimentation des particules agglomérées permet le traitement séparé de la phase solide et de la phase liquide, menant éventuellement à la production d~engrais solide, d~engrais liquide et d~eau répondant au normes environnementales et pouvant être rejetée dans l~environnement ou simplement recyclée.
