Abstract

L'invention concerne un système réacteur biologique et un procédé de traitement d'effluents comprenant un réacteur sous forme de tambour ou de rotor (5) formé par juxtaposition d'une pluralité de plaques lamellaires circulaires parallèlement disposées (1) présentant des ondulations circulaires parallèles (2) et des canaux de collecte (3) le long de la périphérie desdites plaques, ledit tambour ou rotor (5), qui est suspendu par un axe central (9) de rotation, traversant les centres desdites plaques, de manière à être partiellement immergé dans un volume d'eau comprenant ledit effluent, la partie émergée étant en contact avec l'air atmosphérique. Ladite rotation est produite par des forces tangentielles (15) générées dans le tambour lui-même, en conséquence de l'interaction desdits canaux de collecte (3) avec le courant (17) ou avec l'air insufflé inférieurement et de l'un des côtés du tambour par un appareil de soufflage (22, 23).
