Abstract
A filter segment disc of a segment filter comprises a support and drainage plate with slots radiating from the filter hub toward the filter edge. The slots are configured to provide a substantially uniform fluid flow over the filtering medium of the filter segment, reduce residence time of filtrate in the filter, eliminate dead spots in the flow, and facilitate cleaning of permanent filters.
