Abstract (en)
[origin: WO2023006760A1] The present invention relates to a device for extracting phosphorus and nitrogen nutrients contained in a liquid effluent, said effluent being preferably derived from the dehydration of a digestate of a mixture of an organic fraction of municipal waste, sludge and optionally manure and fats, comprising a first reactor comprising a means for extracting CO2; a second reactor comprising a fluidized-bed reactor; a third reactor comprising a means for extracting ammonia and a gas scrubber; the first, second and third reactors being arranged in series.
