The present invention provides an improved distributor including a conduit having an inlet end to receive incoming slurry and an outlet end to feed slurry onto a treatment apparatus such as a filter. A plurality of spaced apart diverter rows are arranged within the conduit between the inlet and outlet ends including a first diverter row comprising one adjustable diverter that is selectively adjustable to divide incoming slurry into either two slurry streams or into three slurry streams. A last diverter row is provided adjacent the outlet end, and the last row includes a plurality of spaced apart non-adjustable diverters make a last division of the slurry before it is discharged onto the filter. At least one intermediate diverter row is provided between the first and last diverter rows, and the intermediate diverter row may include either spaced apart adjustable diverters that can be selectively adjusted to subdivide slurry streams into either two or three additional slurry streams, spaced apart non-adjustable diverters that subdivide slurry streams into two additional slurry streams, or a combination of both adjustable and non-adjustable spaced apart diverters. The each intermediate diverter row contains at least one more spaced apart diverter than the a previous diverter row and one less spaced apart diverter than a following diverter row.
