PRINCIPLE
A collector and distributor is an assembly utilising a header pipe or a hub to which several filtering tubes are attached to enable collection or distribution of a gas or liquid, within a media. The purpose is to eliminate dead zones, wall effects or channelling in order to maximise efficiency.

DESIGN
Assembly - The purpose of the top or bottom, distributor and collector assembly is to collect or distribute a uniform flow within the media or for intermediate collection or distribution in mixed-bed processes. Attention must be applied to the need for backwashing or regeneration. Designs include a hub with spokes or parallel laterals.
Laterals - The smallest diameter is 21 mm and the finest slot is 30 microns. Each lateral consists of either a single wedgewire screen or screen jacket with an internal perforated pipe to control distribution and to add to mechanical strength where required.
Materials - stainless steel 304, 316, 904, hastelloy C276, Inconel 600 and 800 series, titanium T40, Duplex and Superduplex alloys etc.
