Abstract

« Conception d'un réacteur gazosiphon à boucle externe (external-loop airlift reactor) pour le traitement des effluents liquides par Electrocoagulation/Electroflotation ». Inventeurs : Essadki Abdel hafid et Bennajah Mounir La présente invention concerne un appareil de traitement des rejets liquides (eau de lavage, défluorisation, déphosphatation, dénitrification, élimination du Crome, élimination du Cadmium et d'Arsenic, récupération du Cobalt, eaux urbaines, eaux industrielles...). La technologie du procédé repose sur l'introduction de deux électrodes (cathode et anode) dans un réacteur gazosiphon à boucle externe. La dépollution de l'eau s'effectue par voie électrochimique. Les polluants sont récupérés sous forme de flocs à la surface libre du réacteur (de l'appareil). Les bulles d'hydrogène produites au niveau de la cathode, à l¿issu de l'électrolyse de l'eau entraînent les particules déstabilisées du polluant, vers le haut du réacteur formant un floc, facilement récupérable. L'énergie mécanique qui sert pour l'agitation et même pneumatique pour la flottation ont été remplacées par la seule l'énergie électrique qui sert en même temps à l'agitation, la flottation et l'électrocoagulation.
