Abstract (en)
[origin: WO8102570A1] Rotating biological contactor constituted by sheet layers (1) of for example plastic material which has been provided with numerous embossings (2) in order to keep a distance between the different layers (1) and in order to give an increased surface for the growth of microorganisms. In order to give a stiff and at the same time easily fabricated structure some or each of the embossings (2) are at their tops provided with protrading teeth (3) that can grip into corresponding grooves (4) in an adjacent layer. The layers can be identical and offset in order to allow the grooves (4) to be arranged in rows between the embossings (2).
Abstract (fr)
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).
