ProTechtor® Traveling Grit & Grease Bridges

The traveling bridge system utilizes a dual basin configuration consisting of an aerated grit chamber and grease collection chamber. The energy baffles contain the grit and promote settling in the grit basin floor. The grit is then collected via a submerged grit pump attached to the traveling bridge. The grit slurry is fed to a grit classifier, or grit washer, for further cleaning prior to discarding. The grease accumulates within the quiescent grease zone and is positively collected along the entire basin via a skimmer mechanism and pushed into a grease pit or removed via a screw conveyor. The system is fully automated and operates intermittently, run times can be easily adjusted by plant personnel.

Removal Efficiencies
Grit removal efficiency depends on the design dimensions and design peak flow rate. At maximum design flow, the grit removal efficiency will be:

  • 95% of grit greater than, or equal to, 50 mesh in size
  • 85% of grit greater than, or equal to, 70 mesh in size
  • 80% of grit greater than, or equal to, 100 mesh in size
  • 60% of grit greater than, or equal to, 150 mesh in size
  • 15% of grit greater than, or equal to, 200 mesh in size
