Beschreibung
Zusammenfassung:	The invention relates to a method for producing gaseous dihydrogen and ammonium sulfate from an aqueous liquid effluent containing organic and mineral matter or from a mixture of aqueous liquid effluents, said method comprising the following steps: - nanofiltration of said aqueous liquid effluent or of said mixture of aqueous liquid effluents so as to obtain a permeate; stripping of the ammonia from the permeate resulting from said nanofiltration step in an ammonia stripping unit so as to obtain an ammonium sulfate; - treating, via reverse osmosis, at least one portion of the permeate extracted from the ammonia stripping unit after said ammonia stripping step, so as to obtain an osmosed aqueous solution; - electrolysis of at least one portion of said osmosed aqueous solution so as to decompose said portion of said osmosed aqueous solution into at least gaseous dihydrogen.
