Title
(EN) METHOD AND APPARATUS FOR REMOVING PHOSPHATES FROM WATER
(FR) PROCÉDÉ ET APPAREIL D'ÉLIMINATION DES PHOSPHATES DE L'EAU
Abstract
(EN) A method of removing phosphates from water in a continuous process, the method comprising the steps of: (a) passing the water through a first zone in which the pH is adjusted; and (b) passing the water through a second zone in which the water is contacted with magnesium ions; wherein the water is contacted with ammonia in the first zone and/or in the second zone.
(FR) L'invention concerne un procédé d'élimination des phosphates de l'eau dans un processus continu, le procédé comprenant les étapes suivantes : (a) le passage de l'eau à travers une première zone dans laquelle le pH est ajusté ; et (b) le passage de l'eau à travers une seconde zone dans laquelle l'eau est mise en contact avec des ions magnésium ; l'eau étant mise en contact avec de l'ammoniac dans la première zone et/ou dans la seconde zone.
