Title (EN) METHODS OF REMOVING AND RECOVERING PHOSPHORUS FROM AQUEOUS SOLUTIONS
(FR) PROCÉDÉS D'ÉLIMINATION ET DE RÉCUPÉRATION DE PHOSPHORE À PARTIR DE SOLUTIONS AQUEUSES
Abstract:
(EN) Described are methods of removing phosphorous from aqueous solutions using copper-substituted aluminosilicate materials. The copper-substituted aluminosilicate materials are copper-substituted zeolites that are recyclable and have desirable recovery efficiencies. Also described are methods of making copper-substituted aluminosilicate materials, using copper-substituted aluminosilicate materials, systems using copper- substituted aluminosilicate materials, and methods of using these systems.
(FR) L'invention concerne des procédés d'élimination du phosphore à partir de solutions aqueuses à l'aide de matériaux d'aluminosilicate substitués par du cuivre. Les matériaux d'aluminosilicate substitués par du cuivre sont des zéolites substituées par du cuivre qui sont recyclables et ont des rendements de récupération souhaités. L'invention concerne également des procédés de fabrication de matériaux d'aluminosilicate substitués par du cuivre, d'utilisation de matériaux d'aluminosilicate substitués par du cuivre, des systèmes faisant appel à des matériaux d'aluminosilicate substitués par du cuivre et des procédés d'utilisation de ces systèmes.
