Multiple configurations

Filter solutions under-drain assemblies for sand filters, carbon filters, and ion exchange units are offered seen in multiple layouts and configurations. Wedge wire screen laterals and pipe based laterals can be connected to distributor and drain headers by fabricated custom bolt patterns, standard NPT threaded flanged, ANSI connections or welded as one assembly. Laterals are available in all standard pipe and tube diameters for both Header Lateral and Hub Lateral type of assemblies. 

For the most demanding applications

The combination of both wedge-wire having its unique internal support rod structure and ability to be constructed out of stainless steel or many exotic alloys, makes it an easy choice when designing an under-drain system. Incorporating these factors has resulted in a higher collapse strength allowing the design to handle most demanding load applications. Header-Lateral or Hub-Lateral Collector/Distributors fabricated with wedge wire has been seen as a  superior option for retaining media in vessels of all types, i.e. ion exchangers, carbon towers, clay filters, sand filters, and numerous other liquid-solid retention applications in comparison with wire mesh and perforated metal.

Main reason being that wedge wire offers a continuous slot, more open area, precision slots offered (up to 0.002+/- tolerance), and stronger, more durable, reduction in clogging and reduce media abrasion. 

Benefits of our Under-Drains & Ion Exchange Internals include:

  • Continuous slot design provides increased open area for better collection
  • Highly resistant to plugging Stronger and more durable then mesh
  • Choices of fitting types and sizes are available from standard or custom styles
  • Design flexibility
  • High-precision slot sizes slot sizes are available to meet customer's requirements
  • Economy built into designs making them less expensive than other screen
  • Resistant to extreme pressure and temperature variances as well as corrosion
    (depending on the material selection)

Spools
Wedge wire screen has long been considered the most effective media for uses in underdrains/ion exchange systems due to wedge wire having an inherent even pattern of open area that allows for accurate flow distribution.


Standalone Hub
Each system is designed specifically for your application which serves both as a collector of down-coming service flow and a distributor of incoming backwash water. 


Hub & pipe base laterals
Each system is designed specifically for your application which serves both as a collector of down-coming service flow and a distributor of incoming backwash water.
