An oscillating shower (30) for use with a disc filter. The disc filter includes at least one disc (2) and oscillating showers that periodically remove a precoat layer of solids from the surface of the disc. Each oscillating shower (30) moves over the surface of the disc (2) at a varying speed so that water is uniformly applied to the interior and exterior of the disc. At the interior of the disc, where there is a smaller surface area, the oscillating shower moves faster than at the exterior of the disc where the surface area is greater.
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.
