An apparatus which consists of a series of vertical surfaces in the form of a number of thin discs spaced closely together and mounted on a common shaft.

  • Traitement des eaux
CONT

Les disques biologiques. Cette technique [...] remonterait au 19e siècle [...] La biomasse est fixée sur des disques tournant autour d'un axe horizontal et baignant en partie dans l'eau à traiter. De par la rotation, la biomasse se trouve donc alternativement en contact avec l'eau à traiter et l'oxygène de l'air.
