Exceptional performance as a filter underdrain system utilizing Johnson Screens’ world-renowned Vee-Wire® screen technology. Available in stainless steel and in PVC, Triton® underdrains offer maximum surface area to optimize filtration efficiency with the lowest headloss and backwash pump power consumption. The unique bi-directional flow design provides improved bed fluidization – resulting in better media cleaning, longer filter runs and better overall water recovery.

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.

Advantages:
For Operators –
• Lower energy costs due to reduced headloss and
backwash power consumption
• Longer filter runs due better cleaning of filter media
• Better water recovery due to less backwash water
required
• Lower life cycle costs due to the cumulative effect of all of
the above
• Ease of installation compared to other underdrain
designs
• No leveling of laterals
• No grouting
• No special tools or handling
• 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.
• Proven design that delivers operational benefits for clients
• Ease of installation for contractors
• Computer modeling to insure installation operates as designed
• Process optimization after installation based on computation fluid dynamics analysis throughout the design process
