Abstract

Contacteur biologique rotatif constitue de couches en feuilles (1), par exemple en plastique, qui sont pourvues de nombreuses saillies (2) permettant de conserver un certain ecartement entre les differentes couches et d'offrir une surface plus importante pour la culture de microorganismes. Certaines des saillies (2) ou chacune d'entre elles portent a leur sommet des dents (3) qui peuvent s'engager dans des rainures (4) correspondantes d'une couche adjacente, ce qui permet d'obtenir une structure rigide et facile a fabriquer. Les differentes couches peuvent etre identiques et decalees de telle sorte que les rainures (4) se presentent en rangees entre les saillies (2).
