Abstract:
1. A method for simultaneous elimination of orthophosphate and ammonium from an effluent and enabling the production of struvite, wherein the effluent is a wastewater from industrial source, a wastewater from agricultural source or manure, the method comprising the steps of: performing a first electrolytic treatment to said effluent in a first electrolytic reactor, the first electrolytic reactor comprising at least one cathode and at least one anode and being adapted to perform the first electrolytic treatment, thereby eliminating organic matter and calcium present in the effluent that impact on nucleation of struvite; separating a solid fraction from the effluent, performing a second electrolytic treatment to said effluent in a second electrolytic reactor, the second electrolytic reactor comprising at least one cathode and at least one magnesium anode and being adapted to perform the second electrolytic treatment, for producing Mg
