Digester mixing and effluent discharge is achieved by using biogas produced in the digester
- no external energy is required.
No moving internal parts such as agitators are necessary. Digestion of feed substrate with high dry solids content (DS up to 12 %) is possible.
Two section system
Two in-series cascades (two section system) prevent short circuiting.
Sediments and scum layers are avoided through special tank design and are continuously removed with adequate tank equipment. Consequently, clogging and sedimentation problems are reduced to a minimum.
Cycles of operation
Before mixing (feeding)
mixing
after mixing
Integration into overall biogas plant
Of particular importance is careful adaptation and integration of the hydraulic mixing system into the overall plant design. The AAT design can be optimally adapted to the local conditions.
