Wärtsilä Vacuum Collection System

The Wärtsilä vacuum collection system uses differential air pressure to transport sewage from the toilet bowls, and other sanitary fittings, to the Sewage Treatment Plant (STP) or independent collection tank.

Ejectors can be mounted direct to the STP for modular construction without the need for a separate collection tank, and only a small amount of flush water is needed compared to conventional gravity systems.

    Features
    • Ejectors can be mounted direct to the STP for modular construction without the need for a separate collection tank
    • Only a small amount of flush water is needed compared to conventional gravity systems
    • Vertical Lift capability
    • Smaller diameter piping, independent of slope
    • Reduced peak loadings allow use of smaller sewage treatment plant than for gravity systems
    • Ejector performance optimised using Computational Fluid Dynamics (CFD)
