Abstract

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.
