Activated Sludge

RoadTrain® packaged plants can be designed using continuous activated sludge process and configured for nutrient removal if tighter discharge limits are required.

RoadTrain® has been installed in over 150 sites around the world, and is well suited to remote locations where a high level of both process and mechanical robustness is required.

The system is fabricated and assembled offsite to minimize site installation times. Typically the design includes:
  • Inlet screening system
  • Equalization
  • Anoxic zone (if required)
  • Aeration Reactor with diffuser system
  • Aeration Blowers
  • Secondary clarifiers with sludge airlift
  • Disinfection
  • Sludge management
