Abstract
La présente invention concerne un procédé de traitement, et de récupération de composés phosphatés d'eaux usées contenant des phosphates. Le procédé comprend les étapes consistant à : (a) éliminer les fluorures des eaux usées ; (b) récupérer les composés phosphatés des eaux usées en maintenant des conditions de sursaturation pour les composés phosphatés ; et (c) clarifier les eaux usées. Une étape d'élimination de la silice peut éventuellement être réalisée après l'étape (a) et avant l'étape (b).
