Title
(EN) MEDIA FOR A ROTATING BIOLOGICAL CONTACTOR
(FR) ELEMENTS DESTINES A UN CONTACTEUR BIOLOGIQUE ROTATIF
Abstract
(EN)
A random media member (120) for a rotating biological contactor. The media member (120) has a concave hemispherical shaped body (132) with an inner tube with redial plate like ribs and an outer tube with radial plate like ribs, all molded together as an integral part. In one embodiment, a hollow cylinder is molded to the outside of the body. In another embodiment, parallel spaced legs (140) are substituted for the outer cylinder. The tubes and ribs provide surfaces for bacteria to attach.
(FR)
Elément (120) non maintenu en place, destiné à un contacteur biologique rotatif, et comprenant un corps (132) de forme hémisphérique concave pourvu d'un tube intérieur ainsi que d'un tube extérieur possédant tous deux des nervures radiales de type plaque, toutes ces parties étant moulées ensemble afin de former une pièce monobloc. Dans un mode de réalisation, un cylindre creux est moulé sur l'extérieur du corps. Dans un autre mode de réalisation, des pointes (140) parallèles et espacées remplacent le cylindre extérieur. Les tubes et nervures constituent des surfaces de fixation pour les bactéries.
