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
