Abstract
Un nouveau système de traitement deau biologiquement actif pour éliminer les contaminants des effluents industriels et un procédé associé sont décrits. Un nouveau système bioréacteur à flux ascendant doté dune configuration de lit expansé et un procédé permettant de créer un lit expansé pour la libération de gaz sans la libération dun précipité important sont également décrits. Un nouveau système bioréacteur à flux descendant pourvu dun système de dégazage et de lavage à contre-courant automatisé est aussi décrit.
