Title (EN) AMMONIUM/AMMONIA REMOVAL FROM A STREAM
(FR) ELIMINATION D'AMMONIUM/AMMONIAC D'UN FLUX
Abstract: front page image
(EN)In one embodiment, an ammonium removal method can comprise: removing a multivalent cation from a stream comprising ammonium to form a treated stream; converting the ammonium in the stream to ammonia by increasing the pH of the stream; and separating the ammonia from the treated stream to form a separated stream and gaseous ammonia. In another embodiment, an ammonium removal method can comprise: a multivalent cation from a stream comprising ammonium to form a treated stream comprising a total of less than or equal to about 50 ppm by weight of multivalent cations; increasing the pH of the stream to a conversion pH; converting the ammonium to ammonia; and separating the ammonia from the treated stream to form a separated stream and gaseous ammonia.
(FR)Dans un mode de réalisation, un procédé d'élimination d'ammonium peut consister: à éliminer un cation polyvalent d'un flux comprenant de l'ammonium, de manière à former un flux traité; à convertir l'ammonium dans le flux en ammoniac par augmentation du pH du flux; et à séparer l'ammoniac du flux traité, de manière à former un flux distinct et un ammoniac gazeux. Dans un autre mode de réalisation, un procédé d'élimination d'ammonium peut consister: à utiliser un cation polyvalent provenant d'un flux comprenant de l'ammonium, afin de former un flux traité comprenant un total égal ou inférieur à environ 50 ppm en poids de cations polyvalents; à augmenter le pH du flux en un pH de conversion; à convertir l'ammonium en ammoniac; et à séparer l'ammoniac du flux traité afin de former un flux distinct et un ammoniac gazeux.
