triton

The Triton underdrain is designed for the collection and backwash distribution of water and air and includes direct retention of filtering media.

With large open area and the lowest headloss, U-shape channel rods and Vee-Wire® filtering media support profiles, the Triton™ underdrain system offers fine slots to suit any filter media specifications.

Vee-Wire® surfaces are part of all the Johnson Screens® underdrain products. Slot widths can be designed and constructed to handle all types of media to suit different needs.

Triton™ underdrains arrive at the project site fully assembled and require no grouting, special handling or special equipment. With a simple installation and the low headloss, Triton™ underdrains are less expensive to install, operate and maintain.
