ABSTRACT:
A uniform area shower for use with a disc filter. The disc filter includes at least one disc and moving showers that periodically remove a precoat layer of solids from the surface of the disc. In one embodiment the uniform area shower comprises a oscillating shower that is pivotly mounted and travels radially over the disc. In an alternative embodiment the uniform area shower comprises a traversing shower that mounts to a carriage and travels radially over the disc. Each shower includes a controller controlling the drive mechanism to vary the speed of transport of the shower across the surface of the disc such that time spent by the shower cleaning the disc at each radial cleaning position is generally proportional to the radial distance of the cleaning position from the center of the disc so that a wash liquid is applied to a uniform area of 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.
