Title (EN) METHOD FOR RECOVERING N, K, AND P FROM LIQUID WASTE STREAM
(FR) PROCÉDÉ PERMETTANT DE RÉCUPÉRER L'AZOTE (N), LE POTASSIUM (K) ET LE PHOSPHORE (P) À PARTIR D'UN FLUX DE DÉCHETS LIQUIDES
Abstract:
(EN) The present invention relates to a method for recovering N, K, and P from liquid waste stream, preferably from a stream of urine, or from a stream comprising excreta (e.g. faeces, manure, digestate, fertilizer), or from (concentrated) wastewater, for example, municipal (e.g. sewage, septic) and/or industrial wastewater (e.g. food and feed industry, agriculture, mining, etc.); more preferably from urine, such as human or animal urine; most preferably from human urine.
(FR) La présente invention se rapporte à un procédé permettant de récupérer l'azote (N), le potassium (K) et le phosphore (P) à partir d'un flux de déchets liquides, de préférence à partir d'un flux d'urine ou à partir d'un flux comprenant des excréments (par exemple des matières fécales, du fumier, du digestat, de l'engrais), ou à partir d'eaux usées (concentrées), par exemple des eaux usées municipales (par exemple des eaux d'égout, des fosses septiques) et/ou des eaux usées industrielles (par exemple l'industrie agroalimentaire et alimentaire, l'agriculture, l'exploitation minière, etc.) ; de préférence encore, à partir de l'urine, telle que l'urine humaine ou animale ; mieux encore, de l'urine humaine.
