Anaerobic biogas reactor
SEAD®
Veolia Water STI
The SEAD® (Shear Enhanced Anaerobic Digestion) Process is a high rate, short HRT, completely-mixed anaerobic digestion process that is particularly suited for the digestion of sludge and other biodegradable solid wastes and slurries.
The SEAD® reactor typically operates in a once-through mode when treating sludge or slurry with total solids content of 4 percent weight or greater.
A large contact area between the liquid phase and the bacteria is created by the simultaneous disintegration of sludge into small flocs.
The SEAD® reactor is a tall reactor, which is mixed by circulating a large flow of mixed liquor from the bottom of the reactor via one or more high-shear nozzles in the top of the vessel downward into one or more draft tubes.
