TritonTM is a filter underdrain system totally made of stainless steel. It’s a direct retention of the filtering media. The Tritonä underdrain design is based on Johnson screens technology of the stainless steel wedge-wire welded to “U” shaped channel rods.. These channel rods are perforated in order to allow uniform distribution of air/ air+water/water during washing.
Its main functions are:
- Maintain media filter bed (sand, activated carbon, anthracite,…)
- Drain and collect filtered water
- Ensure homogeneous distribution of air and water during backwash phases
Its principal advantages are:
- Low height profile: 130 mm approx.:
* more water volume can be cleaned (increasing capacity)
* more media can be applied (increasing efficiency)
- Wedge-wire technology:
* reduces clogging
* provides the highest open area and lowest headloss
* longer cleaning cycles
* superior filter performance
- Direct media retention:
* eliminates the need for support gravel (saving labour&material costs and increasing media depth)
* slot opening fitted to size of sand and tight slot openings maintained (increasing effectiveness of filter bed)
* fine, mixed media can be directly applied: granulated activated charcoal can be directly applied
- Channel rod technology:
* provides thorough air/water distribution, circulation and mixing when backwashing (eliminating dead spots and mud balling)
- Unique curved scallop design:
* very strong and able to withstand heavy loading
* increases surface collection area to 108% of the filter basin (providing superior cleaning and backwashing and reducing dead zones)
- Adaptable:
* can fit any basin configuration
* adapt to any floor condition (not impacted by a surface that is not completely level)
* adapt to any type of backwashing system
- Lightweight and simple design:
* quick and easy installation
* no special tools, grouting, field assembly or adhesives required
- No filter bed upset and filter media leakage:
* eliminates costly basin shutdown and repairs
* decreases replacement of underdrains and media
