Abstract
Cette invention se rapporte à un rinceur oscillant (30) destiné à un filtre à disques. Ledit filtre à disques comporte au moins un disque (2) et des rinceurs oscillants qui retirent périodiquement une précouche de solides de la surface du disque. Chaque rinceur oscillant (30) se déplace à la surface du disque (2) à vitesse variable de telle sorte que l'intérieur et l'extérieur du disque se trouvent uniformément recouverts d'eau. Du côté intérieur du disque, où l'aire surfacique est relativement plus faible, le rinceur oscillant se déplace plus rapidement que du côté extérieur où l'aire surfacique est relativement plus importante.
