Title (EN) REMOVING AMMONIA FROM WATER
(FR) ÉLIMINATION DE L'AMMONIAQUE DE L'EAU
Abstract:
(EN) A system for removing ammonia from wastewater includes a series of interconnected reactor tubes that each comprise an outer cathode and an inner cathode that is centrally positioned within the outer cathode to form a spacing through which wastewater may flow. At least one of the reactor tubes includes an electrode having a MMO coating. Hypochlorite or another chlorine based element can be supplied to wastewater prior to passing through the reactor tubes. The presence of the hypochlorite within the wastewater and the generation of chlorine by the MMO coated cathode result in an increased level of hypochlorite being present in the wastewater which speeds the breakdown of ammonia. A portion of the wastewater processed through the reactor tubes can be diverted through a feedback path to the input to the reactor tubes to increase the amount of hypochlorite present in the unprocessed wastewater.
(FR) L'invention concerne un système d'élimination de l'ammoniaque des eaux usées comprenant une série de tubes réactionnels reliés les uns aux autres, chacun d'eux comportant une cathode externe et une cathode interne qui est placée de manière centrale dans la cathode externe pour former un espace par lequel les eaux usées peuvent circuler. L'un des tubes réactionnels au moins comporte une électrode recouverte d'un revêtement à base d'oxyde métallique mixte (MMO). De l'hypochlorite ou un autre élément à base de chlore peut être introduit dans les eaux usées avant de circuler dans les tubes réactionnels. La présence d'hypochlorite dans les eaux usées et la génération de chlore par la cathode recouverte de MMO entraîne l'augmentation du taux d'hypochlorite qui accélère l'élimination de l'ammoniaque. Une partie des eaux usées traitées par les tubes réactionnels peut être déviée par un conduit de retour vers les tubes réactionnels pour augmenter la quantité d'hypochlorite présente dans les eaux usées non traitées.
