Riser Tubes, Standpipes, Distributor Tubes for Structural & Clack

A distributor tube consists of a plastic or stainless-steel tube.  Attached to it is a distributor also called a diffusor, collector, strainer or basket.  Its purpose is to produce even flow through an ion exchange or filter media bed.  It also functions as a retainer of the media in the tank.

The screen size of the basket should be appropriate to the media being used.  The tube length is cut to match the tank size and valve.

When to Use Gravel Sub-Fill

Hub & Lateral Systems

For equipment incorporating tank sizes above 14” a hub and lateral design distribution system is used.  Hub and laterals are available in PVC, ABS, Polyproylene and Stainless Steel.Hub-Lateral

Valve size dictates the size of the distributor which in turn dictates the size of the hub. Laterals for filters and ion exchange systems differ in slot size.  Filter media type and backwash rates vary and generally require a slightly larger slot opening from ion exchange resin. Ion exchange laterals usually have .010” slots whereas filter laterals slots are .020”.

Performance of large commercial and industrial systems is impacted by distribution design. Please contact Urbans Aqua for more information about standard and custom distribution systems.
